The Annual Report 2016 portrays an overall picture of IWM activities in 2016 to our valued clients, well-wishers, stakeholders and fellow professionals in a systematic manner. The year 2016 has been yet another year of continued success in the milestone of our accomplishments, depicting the completion of number of significant projects. This year we have provided our services to around 47 different clients and number of projects were around 87. It reflects IWM’s activities in a credible manner for its services to its valuable clients and development partners. Our emphasis was on new areas of knowledge generation through research and studies. We remain grateful to our valued clients for their generous feedback on IWM services through short interactive seminars & consultations that we arranged during the period. CPE Division has been involved in many diversified projects in 2016. Some of them are Formulation of Bangladesh Delta Plan 2100, Assessment of potential effect of surface water withdrawal in the Delta region on water flow and salinity level considering various climate change scenarios, Environmental and Social Impact Assessment study for the Dhaka-Chittagong- Ashuganj Regional IWT Corridor Project (Bangladesh Regional Waterway Transport Project 1), Hydrological and Morphological Study for Installation of 33KV Submarine Cable from Chittagong to Sandwip, Feasibility Study of Capital Dredging in Pussur River from Mongla Port to Rampal Power Plant, Study to prioritize the proposed inland waterways routes for dredging financing and to undertake detailed feasibility study bid packages, Cox’s bazaar airport extension project, feasibility study of LNG terminals etc. WRP Division has been involved quite extensively in various urban water management and drainage related study projects in Bangladesh.

08 Annual Report 2016 RESEARCH ON ASSESSMENT OF EFFECTIVENESS OF MANGROVE FORESTS FOR COASTAL PROTECTION AGAINST CYCLONIC STORM SURGE : BANGLADESH
The study area covers three coastal districts namely mangrove species are available in the selected sites. In Bagerhat, Borguna and Patuakhali located at the eastern this study, mangrove species are short listed based on local people experience and multi-criteria analysis, the criteria are salinity level, tidal characteristics, local availability and economic value for the selected study sites. In this study, Keora and Baen are selected based on the multi-criteria analysis.
In this research work, upgraded and updated hydrodynamic model (water flow model) for Bay of Bengal is used to assess the effects of mangrove afforestation effects. From 1960 to 2015, cyclone SIDR was most devastating for the south-west region of Bangladesh. Therefore, cyclone model is developed for the cyclone Sidr (2007).

The flow of effects of mangrove afforestation during the period of water through the mangrove forest is obstructed by the cyclone. matrix of roots/trunks of the mangrove trees, which creates bed resistance. This bed resistance is represented Mangroves can reduce storm surge water levels by slowing by equivalent Manning number. For calculation of the the flow of water and reducing surface waves (McIvor et equivalent Manning number of mangrove tree, both the al., 2012). It is observed that 50m/100m width of trunks and the roots of Keora (Sonneratia apetala) and afforestation by Baen trees reduces surge level by 3cm to Baen (Avicennia officinalis) species have been considered. 5cm and Keora trees can reduces the surge height by 4cm Manning roughness is calculated based on water depth for to 6cm in the selected site-1 and site-2.

It indicates root system and Eq-2 is used for calculating the manning that the surge attenuation of different widths of roughness both for root and trunk system of mangrove mangroves is non-linear (Zhang et al., 2012).

The river enters into Development of Bhairab River would be technically and socially complex intervention that needs comprehensive analysis of the hydro-morphological scenarios of the river system. IWM was contracted by Bangladesh Water Development Board (BWDB) on the 7th of August 2016 to carry out hydro-morphological mathematical modelling for the Bhairab River.
The main objective of the mathematical modelling study is to assess the feasibility of the envisaged re-excavation of 57km reach of the Bhairab River (from Rashikpur to Subalpur) from technical point of view, and find out The Bhairab River at Karpashdanga (in Chuadanga District) feasible options for water resources development and Bangladesh near Kathuli in Meherpur district, then flows management including flood control and drainage along east-south direction – over Meherpur Sadar and improvement as well as improvement of navigability in Mujib Nagar upazillas of Meherpur district, and Damurhuda the study area. and Jibon Nagar upazillas of Chuadanga district, then The model results will be utilized in finalizing the hydraulic finally meets the Mathabhanga River near Subalpur.

About a decade or so, a regulator was constructed by the Indian Government at her own jurisdiction over the Bhairab River – at about 5km upstream from the India-Bangladesh border. Owing to controlling the river flow by the regulator, the Bhairab started to lose its flow inside Bangladesh. The trans-boundary river suffers severely from scarcity of water for irrigation and farming in the dry season for quite KM 0.00 Kathuli some time. With the prolonged adverse situation, the socio-economic and environmental conditions have deteriorated gradually.

As a result, it had been the demand of local people for Subalpur at KM 86.00 quite some time to make suitable arrangement so that the river water would be available for dry season irrigation and domestic purposes.

22 Annual Report 2016 Survey and Data Management Survey and Data Division
Survey and Data Division (SDT) of IWM conducts hydro- graphic and topographic surveys including collection of water quality and sediment data to support scientifically based management of river erosion, flood and irrigation, water supply and sewerage system. SDT also supports planning and implementation of infrastructure in the communication sector, urban development, industry and energy sectors. The specific areas of SDT activates are: hydro-morpho- logical survey including water quality and sediment sampling and analysis in the rivers and estuaries, flood plain topography and engineering survey. SDT uses the latest survey equipments like Robotic Total Station, RTK-GPS, DGPS, Echosounder, Turbidity Sensor Land level survey by using Total Station and Acoustic Doppler Current Profiler (ADCP) along with the specialised computer software and facilities to conduct the surveys. Addition of new equipment has increased the capacity of conducting Offshore measure- ment like longterm current & wave monitoring in the sea and Measurement of Turbidity and relating with Suspended Sediment Concentration. The surveyed data is promptly processed and analysed in the field and thus maintains a near-online quality control procedure. In the office the data is further verified by the senior professionals before transmitting it to the users and archived in the database for future applications. In addition to collecting data to support modelling activates, SDT also supports different Government Agencies in implementation of dredging activates in the major rivers. Sentinel V ADCP for current & wave data A set of motivated staff comprising highly skilled professionals and field surveyors are engaged for the jobs. The knowledge and skills of the staff are continuously updated and upgraded through on-the-job training, discussions, seminars and workshops at home and abroad.

It has been observed that the potential char WEST BENGAL land in this study area is 2709 Sq. km (average (INDIA) area in 2016-17 period). Generally, this charland is in increasing trend. From four different time spans (2013-14, 2014-15, 2015-16 and 2016-17) the Pearson’s Correlation Coefficient has been found as 0.89 which represents a strong uphill positive linear relationship between area and time. In 2016-17 time span, average permanent char land has been found 1496 Sq. Km and average transitional char land has been found 1213 Sq. Km. The result of this study could be useful for different groups of professionals including policy makers in order to utilize transitional char lands for growing suitable crops. They can also be used for grazing lands for animal Project Area Map
