Athirapally Hydel Electric Project
Athirapally Hydel Electric Project drishtiias.com/printpdf/athirapally-hydel-electric-project Why in News Recently, the Kerala government has approved the proposed Athirapally Hydro Electric Project (AHEP) on the Chalakudy river in Thrissur district of the state. There are already five dams for power and one for irrigation and it will be the seventh along the 145 km course of the Chalakudy river. Chalakudy River It originates in the Anamalai region of Tamil Nadu and is joined by its major tributaries Parambikulam, Kuriyarkutti, Sholayar, Karapara and Anakayam in Kerala. The river flows through Palakkad, Thrissur and Ernakulam districts of Kerala. It is the 4th longest river in Kerala and one of very few rivers of Kerala, which is having relics of riparian vegetation in substantial level. A riparian zone is the interface between land and a river or stream. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. It is the richest river in fish diversity perhaps in India as it contains 85 species of freshwater fishes out of the 152 species known from Kerala only. The famous waterfalls, Athirappilly Falls and Vazhachal Falls, are situated on this river. It merges with the Periyar River near Puthenvelikkara in Ernakulam district. Key Points 1/3 The total installed capacity of AHEP is 163 MW and the project is supposed to make use of the tail end water coming out of the existing Poringalkuthu Hydro Electric Project that is constructed across the Chalakudy river. AHEP envisages diverting water from the Poringalkuthu project as well as from its own catchment of 26 sq km. -

International Journal of Scientific Engineering and Research (IJSER) ISSN (Online): 2347-3878 (UGC Approved, Sr. No. 48096) Index Copernicus Value (2015): 62.86 | Impact Factor (2015): 3.791 Tourism Impact Assessment in Forested Land Using Geo Informatics Subin K. Jose*, Radhulakshmi V S Christ College (Autonomous), Thrissur, Kerala, India Abstract: The environment is being increasingly recognized as a key factor in tourism. The main purpose of tourism activities is the deployment of recreational facilities in an area with tourism potential. Tourism in Athirappilly is the largest industry, that providing several benefits to government and rural peoples. Tourism emergence, which lead naturally or consciously to the degradation of tourist heritage are represented by the natural disturbance of the surface areas of tourist interest and forest cover. The study focused on the impacts of tourism on forest area in Athirappilly region by comparing Landsat images from 1985 and 2012.The work was mapping the affected areas of forest as a result of tourism introduction based on physical characteristics. These are landscape or naturalness (land use/cover), topography (slope, drainage) and settlement size. At First, a list of tourism related criteria were developed. In present study raster based weightage method was carried out for the preparation of tourism disturbance map. GIS based techniques were used to measure the ranking of different criteria according those with the best potential for the study data utilized include survey of India to geographic maps. Subsequently, the forest disturbance map was created based on the combination of criteria and factors with their respective weights. The disturbed area of forest was classified as very high, high, moderate and low. -

Irrigation Department Government of Kerala PERFORMANCE PROGRESSION POLICIES Irrigation Design and Research Board November 2020 PREFACE Water is a prime natural resource, a basic human need without which life cannot sustain. With the advancement of economic development and the rapid growth of population, water, once regarded as abundant in Kerala is becoming more and more a scarce economic commodity. Kerala has 44 rivers out of which none are classified as major rivers. Only four are classified as medium rivers. All these rivers are rain-fed (unlike the rivers in North India that originate in the glaciers) clearly indicating that the State is entirely dependent on monsoon. Fortunately, Kerala receives two monsoons – one from the South West and other from the North East distributed between June and December. Two-thirds of the rainfall occurs during South West monsoon from June to September. Though the State is blessed with numerous lakes, ponds and brackish waters, the water scenario remains paradoxical with Kerala being a water –stressed State with poor water availability per capita. The recent landslides and devastating floods faced by Kerala emphasize the need to rebuild the state infrastructure ensuring climate resilience and better living standards. The path to be followed to achieve this goal might need change in institutional mechanisms in various sectors as well as updation in technology. Irrigation Design and Research Board with its functional areas as Design, Dam Safety, Hydrology, Investigation etc., plays a prominent role in the management of Water Resources in the State. The development of reliable and efficient Flood Forecasting and Early Warning System integrated with Reservoir Operations, access to real time hydro-meteorological and reservoir data and its processing, etc. -

The publication of this TProgress Report seeks to fulfil that assurance. The Government has been publishing such Annual Progress Reports every year. People have the right to know how many of the election promises have been implemented. The Progress Report upholds and justifies such a democratic viewpoint. And with this act, the state of Kerala, which has served as a model to the rest of India in several fields, has taken another step forward. The formulation of an Election Manifesto on the basis of opinions solicited from the people was itself a progressive initiative. Needless to say, it was influenced largely by the views and needs that had crystallized during those circumstances. -
District Survey Report of Minor Minerals Malappuram District
GOVERNMENT OF KERALA DISTRICT SURVEY REPORT OF MINOR MINERALS (EXCEPT RIVER SAND) Prepared as per Environment Impact Assessment (EIA) Notification, 2006 issued under Environment (Protection) Act 1986 by DEPARTMENT OF MINING AND GEOLOGY www.dmg.kerala.gov.in November, 2016 Thiruvananthapuram 1 DISTRICT SURVEY REPORT OF MINOR MINERALS MALAPPURAM DISTRICT (This report is to be submitted along with application for Environmental Clearance (EC) for mining of all minor minerals except river sand) 1 Introduction Malappuram district forms part of Malabar region of Kerala, which is predominantly a landof hills and valleys. Malappuram literally means an elevated place on the top of hills. The district has a unique place in the geological history in view of the fact that Laterite, first identified in the area near Angadippuram by Francis Buchanan is the o o type area of Laterite. The district lies between North latitudes 10 40’ and 11 32’ and o o East longitude 75 50’ and 76 36’. The Nilgiris of Tamil Nadu in the east and Lakshadweep Sea in the west provide natural boundaries. In the north it is bounded by Kozhikode and Wayanad districts and in the south by Palakkad and Trichur districts. The district has a geographical area of 3550 sq.km, which is 9.13 % of the total area of the State. In 2011, Malappuram had population of 4,110,956 of which male and female were 1,961,014 and 2,149,942 respectively. There was an increase of 13.39 percent in the population compared to population as per 2001. The initial provisional data suggest a rd density of 1,158 in 2011 compared to 1,021 of 2001. -

Evaluation of Water Quality of Thuthapuzha Sub-Basin Of
Applied Water Science (2019) 9:70 https://doi.org/10.1007/s13201-019-0937-5 ORIGINAL ARTICLE Evaluation of water quality of Thuthapuzha Sub‑basin of Bharathapuzha, Kerala, India P. Manjula1 · C. Unnikrishnan Warrier1 Received: 4 January 2017 / Accepted: 15 March 2019 © The Author(s) 2019 Abstract Hydrochemical investigation of open well and river water samples of Thuthapuzha Sub-basin of Bharathapuzha, Kerala, was carried out to determine the spatial and temporal variations in the physico-chemical parameters. The suitability of water for drinking and irrigation purposes and the processes controlling the water chemistry were also assessed. The study area experi- ences a humid tropical climate and heavy rainfall of ~ 3830 mm/year. Thirty-fve open well and nine river water samples were collected during the pre-monsoon, monsoon and post-monsoon seasons. The chemical properties of the river water samples were dominated by alkaline earths and weak acids (CaHCO3 type). Even though majority of the open well samples belonged to CaHCO3 type, few samples belonged to NaCl, mixed CaMgCl and mixed CaNaHCO3 water type. The groundwater and river water chemistry of the region was infuenced by the chemistry of the host rock rather than precipitation and evaporation. Except pH and the total iron concentration, all other physico-chemical parameters of the open well samples of the study area were within the acceptable limit of drinking purposes. The physico-chemical parameters of the entire river water samples were within the acceptable limit for drinking purpose. The entire open well and river water samples were suitable for irrigation purposes. Keywords Hydrochemistry · Thuthapuzha Sub-basin · Kerala · India Introduction these studies reveal that both rivers and groundwater in India are facing water quality issues.
