The proposed Shoreline Protection Structures (SPS) is a field of six groynes along the coastline of Mandaikadupudur & Neyyur ,situated in Taluk near Nagerkoil in the Kanyakumari district.

The project location is geographically located between 080 09’ 30.9” to 080 09’ 44.1” N Latitude and 770 16’ 35.5” to 770 16’ 58.8” E Longitude along the West Coast in Arabian Sea interface, adjoining to Kerala State Coastline.

Precisely, the coast of Kanyakumari district is learnt to have become more vulnerable to natural coastal calamities and the fear factor of Tsunami, made the shoreline protection structures as utmost necessary and implementation of such projects are planned with emergency priorities.

The project location of Shoreline, in the Nagercoil Taluk of Kanyakumari District, has been characterized for erosion prone, since Tsunami 2004. From several research studies, including the one by IIT-M, It is evident that this stretch of coastal line in Nagapatinam district needs protection from the on-set erosion processes and other natural calamities like storm surges.

The proposed shore line protection works for about 0.85 km stretch is envisaged for providing a field of six Groynes and financial allocation was made in 13th Finance commission to construct. This initiative of Government clearly indicated the seriousness of this coastal threat in the National Agenda.

The Public Works Department (PWD) , Anti Sea Erosion Division, Government of Tamilnadu is the implementing agency and perhaps already started the project in key areas of habitation in the 1 km stretch of coastal line..

The groynes are envisaged as a field to reduce long shore transport by trapping sand and causing the shoreline orientation to change relative to dominant wave directions.

Centre for Environment, Health and Safety ANNAMALAI UNIVERSITY SHORELINE PROTECTION STRUCTURES Mandaikaduputhur, KANYAKUMARI DISTRICT PUBLIC WORKS DEPARTMENT / ANTI SEA EROSION DIVISION RISK ASSESSMENT AND MANAGEMENT PLAN GOVERNMENT OF TAMILNADU Centre for Environment, Health &Safety (CEHS), Annamalai University was entrusted with consultancy for Environmental Impact Assessment Study.

Centre for Environment, Health & Safety (CEHS), Annamalai University is the 1 accredited EIA organization by QCI under NABET for Ministry for Environment , Forests & Climate Change, Government of .

Public Works Department, Anti Sea Erosion Division,Government of Tamilnadu has proposed to augment and upgrade the existing Shoreline Protection Structures (SPS) in the Mandaikadupudur and Neyyur Coastal lines, with a Groyne field. This project of SPS, along the coastline of villages is for about 1 Km stretch of Coastline. The project location has more valuable land and human settlement which have become vulnerable to erosion and sea level rise. The extent of proposed project is around 0.85 km of coastal stretch near Kolachal, Kanyakumari district that encompass coastal villages, Mandaikadupudur and Neyyur. The proposed SPS will have Groyne Structures constructed with natural stones without any cement or any other construction materials. The high strengthand inert stones will not pose any risk, except to human safety during construction and aftermath. There will not be any discharge or emission and that there will not be any environmental risk due to SPS. During construction or aftermath, the handling of Rubbles or its unlikely displacements or falls, there is no credible risk involved in the proposed project of PWD. There is no project or activity based risk. Anyhow, the location of the project is vulnerable for natural hazards. The handling of Rubble is vulnerable for risk to human health and minor injuries and accidents. Hence, a comprehensive RA was carried out for proper implementation of the project and maintenance of the structures.

I.INTRODUCTION

The scope and purpose of this report is to identify the main hazards which can threat the proposed SPS and assess the potential risk of the groyne field in order to achieve a state of preparedness, or implement mitigating actions, which will reduce the impact of them. A simple identification of the hazards would serve little purpose if they were not assessed and action taken on such assessment.

Any coastline and marine areas are vulnerable to natural disasters like cyclone, Storm, earth quake, Flood, Tsunami, rise in tides, etc. The proposed SPS is essentially to prevent erosion and protect shoreline in Mandaikaduputhur and Neyyur Villages, Kalkulam Taluk, Kanyakumari District.

Activities during construction and post construction pose little hazards, if any, due to human error and stone displacement or fall leading to injury and health impairment.

The Eroding coastline in the project location can be seen in Fig 1.1 to 1.4. It is the demand of nearby coastal community to construct SPS consists of Groynes. The risk assessment was initiated to evaluate identification of hazards, prevention techniques, mitigation strategies and emergency preparedness plans.

The layout of the proposed SPS is given in Fig 1.5. The Satellite Imagery of the proposed SPS in the project location is presented in Fig 1.6.

There is no project specific- credible risk. However, the project location, which is an eroding shore with coastal processes do require evaluation of risks of the proposed SPS – location specific.

Kanyakumari and more specifically, Mandaikaduputhur is disaster prone to natural calamities like Cyclone, Storm Surge, Earth Quake, Sea level rise, etc,. The construction materials of Rock Mounds are risky to handle and would require proper maintenance to prevent and protect any unlikely displacements or fall.

This report delineated the location specific risks to SPS and drawn a detailed scheme for effective management to provide risk-free environment to fisher folk in the post project scenario.

II. METHODOLOGY OF RISK ASSESSMENT

Risks are emanating from either project activity or the location of the project. The proposed project of Groyne Field has no risk except the following:

 Human error in handling Rock or Rubble Mounds

 Displacement or fall of Rock Mounds

These two are very unlikely events and with less credibility to happen to lead an accident or an injury.

However, the project location is vulnerable to coastal extremes like Cyclone, Storm Surge, Earth Quake and including Tsunami. Hence, the following methodology was adopted for identifying and listing of risk scenarios.

Identification Listing the main hazards

Assessment Assessing the probability of an incident and its consequences

Assessing which hazards should be awarded priority consideration Prioritisation for mitigation/emergency planning

Considering the actions which could be taken to mitigate the effects of a potential incident. This will usually mean the Mitigation preparation of an emergency plan or identifying existing plans which are relevant

Taking action as appropriate taking into account the processes set Management Plan out above

There are several methods by which hazards can be assessed leading to a formal “Risk Assessment”. However, many of the methods do not lend themselves readily to the type of hazards that are being considered here. The emergency management assessment is looking at hazards over which local authorities or indeed any other organisations have little or no control. In such cases, arrangements to reduce the impact on the community are necessary.

Centre for Environment, Health and Safety ANNAMALAI UNIVERSITY SHORELINE PROTECTION STRUCTURES Mandaikaduputhur, KANYAKUMARI DISTRICT PUBLIC WORKS DEPARTMENT / ANTI SEA EROSION DIVISION RISK ASSESSMENT AND MANAGEMENT PLAN GOVERNMENT OF TAMILNADU

Such hazards include severe weather, transport accidents, etc. Those activities or hazards over which there is an element of control, however small or remote have been assessed to determine any actions could be taken to mitigate the effects or likelihood of an incident.

In this project activity, there is no credible cause for any risk scenario from the proposed structures. The human error during construction is the only credible cause for an accident which could lead to injuries and the impact is temporal and retrievable.

III. HAZARD AND RISK IDENTIFICATION

This section will aim to identify the hazards, which may have the potential to cause disruption, damage to property, or endanger life in and around the SPS. The section will list the hazards in three categories, Natural, Technological and Others. A brief description of each hazard’s characteristics will be given.

“A hazard is best viewed as a naturally occurring or human induced process or event which has the potential to create loss.” The hazards covered in this section are ones viewed as most prominent to the Project location of SPS and are not an exhaustive list of all known hazards. In this section each hazard will be viewed as a primary hazard. This chapter therefore provides the understanding of hazards in an attempt to increase the accuracy of the risk assessment.

3.1 Natural Hazards

3.1.1 Extreme Weather (Cyclone/Storm/Storm Surge)

In this report, severe weather includes heavy rain, cyclone, and storm surge. These types of weather storms usually result in the disruptions to transportation routes, power and utility failure, immobilizing fishing activity. The India Meteorological Department (IMD) provides a certain amount of warning for these types of hazards and they rarely cause lengthy disruptions apart from in extreme cases when severe damage is caused to infrastructures.

Any incidence of depression in the Arabian Sea region is not a frequent affair and least so in the North East monsoon. Storms are least frequent from January to March and most frequent in the months of October and November. Storms are also as frequent in May and in August. Severe storms are most frequent in May and in October and November. During October, the entire region to the north of about Latitude of 80N is liable to be affected. This is one of the three months where storms are most likely to be severe. In the month of November, severe storms are more frequent and the whole region is likely to be affected.

The effect of extreme weather would most likely be a disruption of vital services such as water, sewer, power and transportation; damage to and disruption of emergency response facilities, resources and systems. As per the Vulnerability atlas of cyclone frequency and wind hazard map, Mandaikaduputhur falls in the Moderate Damage Risk Zone-B (Figure-3.1).

Centre for Environment, Health and Safety ANNAMALAI UNIVERSITY SHORELINE PROTECTION STRUCTURES Mandaikaduputhur, KANYAKUMARI DISTRICT PUBLIC WORKS DEPARTMENT / ANTI SEA EROSION DIVISION RISK ASSESSMENT AND MANAGEMENT PLAN GOVERNMENT OF TAMILNADU

Hence, a “worst case scenario” would affect the port and also the entire community to a significant level.

3.1.2 Coastal Erosion

Coastal erosion is the gradual removal of sediments (including beach sand and topsoil) in coastal areas due to wave and tidal action. Wind, wave and tidal action can impact large portions of the shoreline, including beaches and small cliff areas. Erosion may cause damage to roadways, residences, and other structures, and it may also lead to a loss of vegetation. The impacts of erosion on coastal areas are generally gradual, although dramatic coastal erosion may occur following a storm or flood event.

The present project is Engineered Structures Viz., Groynes. The proposed structures are essentially to prevent such erosion and to protect the shoreline.

3.1.3 Flooding

Floods constitute one of the most potentially serious hazards facing the District. Flooding occurs when abnormally high water levels overtop the natural or artificial banks of a river or other watercourse. The project location of SPS has no estuary or river. The District is not having any major river line or fluvial flooding which can result from either long durations of rainfall causing watercourse to rise above their normal level (usually winter scenario) or short intense rainfall events causing the watercourse to rise rapidly due to overland flow (typically a summer scenario). The magnitude of flooding is influenced by the following factors, precipitation amount, intensity and distribution, soil moisture, seasonal variation in vegetation and infiltration capacity of the ground surface – influenced by the degree of urbanisation. The inundation caused by river line or fluvial flooding may vary from a few hours to many days.

3.1.4 Earthquake

An earthquake is the sudden motion or trembling in the earth caused by an abrupt release of slowly accumulating strain. This sudden release results in ground shaking, surface faulting, and/or ground failures.

The Indian subcontinent has a history of devastating earthquakes. The major reason for the high frequency and intensity of the earthquakes is that the Indian plate is driving into Asia at a

Centre for Environment, Health and Safety ANNAMALAI UNIVERSITY SHORELINE PROTECTION STRUCTURES Mandaikaduputhur, KANYAKUMARI DISTRICT PUBLIC WORKS DEPARTMENT / ANTI SEA EROSION DIVISION RISK ASSESSMENT AND MANAGEMENT PLAN GOVERNMENT OF TAMILNADU rate of approximately 47 mm/year. Geographical statistics of India show that almost 54% of the land is vulnerable to earthquakes. A World Bank & United Nations report shows estimates that around 200 million city dwellers in India will be exposed to storms and earthquakes by 2050. The latest version of seismic zoning map of India given in the earthquake resistant design code of India [IS 1893 (Part 1) 2002] assigns four levels of seismicity for India in terms of zone factors. In other words, the earthquake zoning map of India divides India into 4 seismic zones (Zone II, III, IV and V) unlike its previous version which consisted of five or six zones for the country. According to the present zoning map, Zone V expects the highest level of seismicity whereas Zone II is associated with the lowest level of seismicity. The latest seismic zoning map released by the India Meteorological Department website is shown in the Fig-3.2. According to the seismic zoning map, the proposed project location of SPS falls in the Zone II.

As per the National Disaster Management Authority of India, the Geographical areas which fall under seismic zones III, IV and V, which are vulnerable to potential impact of earthquakes, landslides, rock falls or mudflows. Though the project location of SPS comes in the Zone II, the risks involved due to earth quake cannot be ruled out.

3.1.5 Tsunami

Tsunami is a series of travelling ocean waves of great length and long period usually generated by submarine geophysical displacement. May or may not be preceded by an earthquake.

Tsunamis are also generated by volcanic eruptions and submarine landslides, nuclear explosions, and even due to impact or fall of large size meteorites, asteroids, and comets from outer space. Tsunami genic zones that threaten the Indian Coast have been identified by considering the historical tsunamis, earthquakes, their magnitudes, location of the area relative to a fault, and also by tsunami modelling. Both the east and west coasts of India and the island regions are likely to be affected by tsunamis from the five potential source regions, viz., the Andaman-Nicobar- Sumatra island arc, Indo-Burmese zone, Nascent Boundary (in the central Indian Ocean), Chagos archipelago and the Makransubduction zone.

According to the latest seismic zone map of India (Figure-3, IS: 1893, 2002), about 59 percent of India’s land area is vulnerable to moderate or severe seismic hazard. The present project district has already experienced a Tsunami in 2004.

Tsunami 2004, which heavily affected the project location, is the reason for proposing the SPS. Hence, the proposed project will reduce the risk or hazard out of this attribute.

3.2 Technological Hazards

The proposed SPS has no process or manufacturing activity. This will only stand as a physical barrier to regulate the erosion or accretion and protect the shoreline.

3.3 Other Hazards

Fire, Terrorism or any public disorder will have no cause of any risk in the post project scenario.

IV. RISK ASSESSMENT

Risk is a function of the probability (likelihood) of particular hazards arising and the potential impact which would result from these. Therefore, risk is the level of perceived exposure of people, services or processes to the effects of identified hazards. Risk assessments are part of everyday life. People, and what they value, are the essential point of reference and basis for all risk assessments.

4.1 Probability (Likelihood) and potential Impact

The risk of each hazard has been calculated on two criteria - probability and consequences. Probability is the likelihood of a particular event occurring. Consequences are the expected number of lives lost, persons injured, scale of damage to property and disruption of essential services and economic activity resulting from the impact of a particular natural or manmade hazard. The probability and consequences of the hazards identified in the previous section were assessed on a scale 1-5. Very unlikely probability or very minimal consequences being rated at 1, with very likely probability and very severe consequences rated at 5. The probability and consequences are then multiplied to determine the risk category. The Risk Category’s are illustrated in the Table-4.1.

Centre for Environment, Health and Safety ANNAMALAI UNIVERSITY SHORELINE PROTECTION STRUCTURES Mandaikaduputhur, KANYAKUMARI DISTRICT PUBLIC WORKS DEPARTMENT / ANTI SEA EROSION DIVISION RISK ASSESSMENT AND MANAGEMENT PLAN GOVERNMENT OF TAMILNADU

This section identifies the calculated risk of each hazard and subsequently places each hazard within a suitable risk category. Risk is constantly changing, which is why the reviewing of risk assessments is essential to ensure that when risks develop appropriate amendments can be made. The risk associated with particular hazards in the project location of SPS area will fluctuate, however at the time of assessment the risk categories include the following hazards and are presented in the Table 4.3.

V. PRIORITISATION

To arrange or deal, the order of importance, prioritisation is essential. The hazards identified in this document have been prioritised according to risk and are presented in the Table-5.1

Hazard impact assessment is nothing but the consequences of an effect or disaster. The consequences of the various hazards are analyzed and presented. In order to understand the severity of the hazard or accident, it is necessary to know its impacts. In this section, the report seeks to know the various consequences of disasters that would need Mitigation strategies to minimize the property damage and or fatalities.

6.1 Extreme Weather (Cyclone/Storm/Storm surge)

Severe weather has the potential to cause major disruption to the project location of SPS in terms of property damage, pollution and threat to people’s lives. Some consequences include the following.

 Large numbers of casualties  Destruction of or damage to property including MFVs  Homelessness  Loss of a utility or utilities  Disruption of transport or communications  Increased requests for services i.e. property repairs  Loss of facilities or service provided by a premises  Reduced ability to provide normal services due to staff or other shortages  Increased public information requirements

The probability of the occurrence of severe weather in the Project location of SPS is high.

6.2 Coastal Erosion

The Coastal erosion has become a serious coastal threat in the project location as could be appreciated from Fig 1.1 to 1.4.

The probability of occurrence of coastal erosion in the Project location of SPS area is high.

6.3 Flood

There is no river in the project location. The incidences of flood and storm surges will not have impact on the project location.

Centre for Environment, Health and Safety ANNAMALAI UNIVERSITY SHORELINE PROTECTION STRUCTURES Mandaikaduputhur, KANYAKUMARI DISTRICT PUBLIC WORKS DEPARTMENT / ANTI SEA EROSION DIVISION RISK ASSESSMENT AND MANAGEMENT PLAN GOVERNMENT OF TAMILNADU The probability of the occurrence of river line flooding is NIL.

6.4 Earthquake

The Kanyakumari District does not have a history of earthquake. Though this area comes under the seismic zone II with a low seismicity, the following consequences may result in case of an earthquake. They are:

 Injury and fatalities  Damage to property  Loss of facilities or service provided by a premises  Distressed persons either effected directly or indirectly by the incident  Loss of one or more utilities  Disruption of the transport system  Loss of communications  Pollution  Public health issues  Economic disruption  Damage to structures  Evacuation  Media focus  Increased public information requirements  Disruption to infrastructure

The probability of the occurrence of earthquake within the District is Low.

6.5 Tsunami

The Indian Ocean Tsunami of 26th December 2004 is one of the most destructive Tsunamis known to have hit India and 13 other countries in the Indian Ocean region. With a combined toll of 238,000 casualties (including 51,500 people missing), and roughly more than 1.5 million people displaced in fourteen countries, this tsunami resulted in damage and destruction of property, assets and infrastructure in the coastal areas. In India 10,749 people lost their lives due to the tsunami and 5,640 people were missing in the Tsunami affected areas mostly in the coastal Tamilnadu. The consequences of the Tsunami are as follows:

Centre for Environment, Health and Safety ANNAMALAI UNIVERSITY SHORELINE PROTECTION STRUCTURES Mandaikaduputhur, KANYAKUMARI DISTRICT PUBLIC WORKS DEPARTMENT / ANTI SEA EROSION DIVISION RISK ASSESSMENT AND MANAGEMENT PLAN GOVERNMENT OF TAMILNADU  Injury and fatalities  Damage to property  Loss of facilities or service provided by a premises  Distressed persons either effected directly or indirectly by the incident  Loss of one or more utilities  Disruption of the transport system  Loss of communications  Pollution  Public health issues  Economic disruption  Damage to structures  Evacuation  Media focus  Increased public information requirements  Disruption to infrastructure

The probability of the occurrence of Tsunami in the District is Low.

6.6 Transport Incidents

The probability of the occurrence of incident due to transportation is Nil.

6.7 Fire

The probability of fire in within the Project location of SPS is Nil.

6.8 Terrorism and Public Disorder

The probability of Terrorism and Public Disorder is Nil.

Centre for Environment, Health and Safety ANNAMALAI UNIVERSITY SHORELINE PROTECTION STRUCTURES Mandaikaduputhur, KANYAKUMARI DISTRICT PUBLIC WORKS DEPARTMENT / ANTI SEA EROSION DIVISION RISK ASSESSMENT AND MANAGEMENT PLAN GOVERNMENT OF TAMILNADU VII. MITIGATION

Mitigation is the effort to reduce loss of life and property by lessening the impact of disasters. This is achieved through risk analysis, which results in information that provides a foundation for mitigation activities that reduce risk, and the consequences of disasters. In this section the report seeks to identify plans and systems to mitigate the effects of any hazard, and to identify further actions to be taken to reduce the risk to acceptable limits.

7.1 Extreme weather (Cyclone/Storm/Storm surge)

Action to prevent an emergency from happening or lessen the impact if it does happen (i.e. flood plain management, building codes, land use planning, strapping water heaters, etc) is known as mitigation. This is the most crucial component in any disaster management exercise. It may be in the form of creating awareness, building long term or short-term infrastructure in hazard zones, aid planning, etc… Mitigation opportunities may arise any time where the awareness of the disaster is high, e.g., disaster scare-however unfounded it seems, post disaster, during disaster or during such seasons in areas prone to disasters. Attention to such opportunities can help in tackling any future emergencies. The Mitigation measures to be considered before, during and after the Cyclone is summarized and presented in the Table-7.1

7.2 Costal Erosion

The present project of SPS with Groynes will reduce the vulnerability of the project location to erosion.

7.3 Flood

In case of Flood, the proponent should coordinate with the District level committees.

7.4 Earthquake

Earthquake mitigation is difficult because these events are not well predicted. Increased awareness and community-wide education about what do before, during, and after an earthquake are essential to mitigate this potential hazard. The following actions on mitigation strategies would reduce the damage and risk.

 Major Emergency Scheme  Evacuation routes and Rest Centre Plan  Media and Public Relations Plan  Help lines  Service Plans  Premises Plans  Liaison with other agencies such NDMA and DDMA, etc.  Social Services and Health  Counselling Plan  Cultural Services plan  Public education and awareness of these systems and rout
