I am happy to observe that IWM has come a long way to establish itself as a prime instute in the country as well as in the region, dealing with the complex technology of mathemacal modelling, computaonal 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 mathemacal modelling tools. Today’s success of IWM is backed by the dedicaon of its skilled human resources that has made possible to achieve the result-oriented soluons 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 organisaon 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 mathemacal modelling study for safe drinking water sources idenficaon in 148 pourashavas. Due to geographical locaon 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 connue to consider IWM as one of the most reliable instuons in devising sustainable soluons 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 mathemacal 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 aract and to retain human resources, IWM will be able to address the problem in the coming years. The Instute organised a number of naonal and internaonal seminars /workshops including climate change issues and the use of mathemacal modelling in IWRM which were aended largely by the user and the client community. It is encouraging to note that IWM has been connuously 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 educaonal and research instuons in the country and abroad is connuing. These famed instuons 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 contribuon and connuous support over the years. I also extend my best wishes to the commied staff of IWM for their efforts in enhancing the image of the instuon 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 variaon and geologi- cal characteriscs together with torrenal 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 resulng in the disrupon 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 quanty 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 conjuncve use. Eventually DWASA has developed a strategic development plan to use alternave 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.

Department of Public Health Engineering (DPHE) has taken up a project entled Groundwater Management and TPP for Survey, Invesgaon and Feasibility Study in Upazilla and Growth Centre Level Pourashava having no Piped Water Supply System. In this connecon, DPHE has appointed IWM to conduct Mathemacal Modelling Study for Safe Drinking Water Source Idenficaon in 148 Pourashavas. The Project is very relevant to the country policy for water supply and sanitaon. It, along with other sanitaon projects in neighbouring countries, will synergis- cally improve the regional environmental sanitaon situaon. The 148 Pourashavas selected for study are distributed all across Bangladesh. It involves people from various cross- secons of the country where different livelihoods prevail and also the living style and standards varies. On the basis of a baseline status of the 148 Pourashava by DPHE, review was done for selecon before the commencement of the study.

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 abstracon volume. Such situaon should be avoided either by decreasing depen- dency on groundwater or by gradually increasing the ground- water storage volume by arficial recharge to aquifer systems. Besides, Buriganga and Sitalakhya rivers are unsuitable Recharge Pit and Injecon wells as the source of water supply due to connued polluon. Considering the threat of groundwater mining, DWASA has decided to carrying out Dupila aquifer is the best depth locaon for making a pilot study on arficial recharge to aquifer through rain arficial recharge through gravity inflow in Upper Dupila water harvesng. Accordingly the study on “Arficial aquifer system.

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. Populaon of the city is constantly increasing along with rapid and unregulated industrializaon. 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 acvies 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. As one of the soluons to overcome the situaon, Bangla- pass and guide bundh have also been kept. desh Water Development Board (BWDB) took up the Instute of Water Modelling (IWM) has been engaged by Buriganga River Restoraon Project.
