I am happy to observe that IWM has come a long way to establish itself as a prime ins tute in the country as well as in the region, dealing with the complex technology of mathema cal modelling, computa onal hydraulics and allied sciences, and addressing many water-related problems of the country. I also appreciate that IWM has expanded its services to Malaysia, Tajikistan, Nepal with its state-of-the-art mathema cal modelling tools. Today’s success of IWM is backed by the dedica on of its skilled human resources that has made possible to achieve the result-oriented solu ons to complex hydrological, hydraulic and morphological problems of the river systems of the country. Over the last few years, IWM has only grown in strength to become a unique organisa on in the country. I have been informed that the year 2010 was tagged as a year of success as the biggest ever project in IWM was entrusted by Department of Public Health Engineering for mathema cal modelling study for safe drinking water sources iden fica on in 148 pourashavas. Due to geographical loca on of the country, Bangladesh has to face frequently lot of water related challenges and the country has become vulnerable to flood, draught, cyclone, river erosion, and other natural disasters. IWM developed models by using state-of-the-art technologies, significant development has been made to address lot of these challenges as more government and non-government agencies of the country as well as donors con nue to consider IWM as one of the most reliable ins tu ons in devising sustainable solu ons to these complicated water-caused hazards. Being the Chairperson of IWM Board of Trustees, I am happy to know that new agencies and departments are considering IWM to use the mathema cal modelling service for their projects. At the same me I have also been informed that the resource constraint and a high turnover rate has now become a big challenge for IWM. I trust that, by devising sustainable mechanism to a ract and to retain human resources, IWM will be able to address the problem in the coming years. The Ins tute organised a number of na onal and interna onal seminars /workshops including climate change issues and the use of mathema cal modelling in IWRM which were a ended largely by the user and the client community. It is encouraging to note that IWM has been con nuously pursuing HRD to improve its staff resources with the latest update. I expect that the development partners will come up to fund the planned HRD programmes in the coming years. IWM’s linkage with other educa onal and research ins tu ons in the country and abroad is con nuing. These famed ins tu ons include BUET (Bangladesh), DHI (Denmark), AIT (Thailand), HR Wallingford (UK) and UNESCO-IHE, the Netherlands, Tuffs University and Tennessee Technological University (TTU), USA. I would like to thank the members of the Board of Trustees of IWM for their generous contribu on and con nuous support over the years. I also extend my best wishes to the commi ed staff of IWM for their efforts in enhancing the image of the ins tu on and country. I wish IWM a bright future.

Unstable steep slope, weak and fragile geological forma- on of young mountains along with heavy monsoon rainfall has made Nepal one of the most hazardous areas in the world. Because of its topographical varia on and geologi- cal characteris cs together with torren al rain during monsoon season, the country frequently suffers from different kinds of water induced disasters like soil erosion, land slide, debris flow, floods, etc. These disasters cause loss of life and property and pose severe hazards to physical infrastructure resul ng in the disrup on of the social and economic development of the country. Kathmandu valley frequently experience severe flash floods caused by heavy rainfall. A major flood disaster occurred in the Bagma river basin in 1993 which was caused by the intensive rainfall in the central region of Nepal. The floods caused heavy damages to Bagma barrage and the Kulekhani Hydropower Plant. Many villages and several bridges were washed away and the disaster claimed the life of 1336 persons and injuries to 163 persons.

It is a great challenge for DWASA to ensure water supply in adequate quan ty and quality round the year. In an effort to reduce the overwhelming dependence on groundwater resources for water supply, groundwater and surface water has been proposed for conjunc ve use. Eventually DWASA has developed a strategic development plan to use alterna ve surface water sources. The total water demand of the Dhaka city has been calculated approxi- mately at 2,470 MLD in 2009, which is predicted to increase to around 4,130 MLD in 2025. The “Feasibility Study of Pagla/ Keranigonj Water Supply Project’ was launched in April, 2010 and completed in Dec, 2010. A 900 MLD Surface water Treatment Plant, the largest in Bangla- desh was designed by IWM 10 for the project in two phases. In the first phase 450MLD treated water will be produced and in the 2nd phase 450 MLD water will be added to the system. The Proposed Infrastructure for major objec ve of the study is Pagla/Keraniganj WTP Project to carryout detailed feasibility study of the project which Legend includes (i) Op on study for River/Canal Waterbody Crossing Intake selec on & WTP (ii) Proposed Padma Bridge WTP Road Injection Point Assess dependable flow of Transmission Main Booster Pump Station Padma River (iii) Iden fica on DWASA Pipe Line Intake Pump Station of water treatment process (iv) Outline design of project Proposed Infrastructure of Pagla/Keraniganj Water Treatment Plant components (v) Es ma ng cost of the project. nent structures of the project including cost es mates Extensive use of 2-dimensional morphological model has were made; EIA, SIA and financial and economical been done to inves gate sedimenta on in the intake, analysis of the project shows that the project is economi- river bank stability and op ons for bank protec on works. cally viable with no major environmental and social Network models have been used to design the transmis- adverse impacts. sion lines and booster requirement.

Groundwater is the prime source of water supply in Dhaka city, which is about 87% of the present total supply. This unusual aquifer pumping is endangering the aquifer environment and also becoming a threat to sustainability of the city itself. This threat is being developed because of imbalance in groundwater recharge and abstrac on volume. Such situa on should be avoided either by decreasing depen- dency on groundwater or by gradually increasing the ground- water storage volume by ar ficial recharge to aquifer systems. Besides, Buriganga and Sitalakhya rivers are unsuitable Recharge Pit and Injec on wells as the source of water supply due to con nued pollu on. Considering the threat of groundwater mining, DWASA has decided to carrying out Dupi la aquifer is the best depth loca on for making a pilot study on ar ficial recharge to aquifer through rain ar ficial recharge through gravity inflow in Upper Dupi la water harves ng.

The dry season flow of the peripheral rivers of Dhaka City is declining day by day. The conveyance capacity of the surrounding rivers is reducing due to sedimenta- on and other hydraulic and morphological changes. Popula on of the city is constantly increasing along with rapid and unregulated industrializa on. Currently, more than 7,000 industries of various sizes operate within greater Dhaka area and produce more than one million cubic meter of heavily polluted industrial wastewater most of which is disposed to the rivers without treatment. With the increased socio- economic ac vi es and the reduced flow, the water quality of these rivers deteriorated significantly. 14 Specially, the water quality of the Buriganga (on the Silted up offtake of New Dhaleswari bank of which the capital city Dhaka stands) degraded beyond tolerable limit.
