Road/bridge infrastructure management Hot water dispersion and cooling water intake in rivers for Power Plants.

The division inherits its strength from its involvement, for more than 15 years, in the field of morphological modelling of more than 1,500kms of large, meandering and braided rivers of Bangladesh including 3 major rivers - the Ganges-Padma, the Brahmaputra-Jamuna and the Meghna.

06 Mathematical morphological modelling for the Ganges Barrage Project

In order to utilize the Ganges water under India-Bangladesh treaty, for benefit of the people living in Ganges Dependent Area and to offset the negative impacts of the withdrawal of water upstream of Farakka on agriculture, fisheries, and ecology of the south-western region of Bangladesh, it is rather imperative to construct a barrage across the Ganges within Bangladesh.

Engaged as sub-consultant, Institute of Water Modelling carried out mathematical modelling for the feasibility study and detailed engineering design.

With a view to assess the changes due to construction of the large structure, comprehensive morphological modelling has been carried out to develop two-dimensional (2D) morphological models with different extents using the State-of-the-Art modelling tool MIKE21C.

Techno-economic feasibility and environmental study for the development of sea port at Rabnabad channel in the Patuakhali district

For a smooth and balanced economic growth as well as social development in the central coastal zone, establishment of a sea port was felt essential. IWM carried out a techno-economic feasibility and environmental study in this respect. IWM study included site selection analysis of the project to select and recommend the most preferable site for the new sea port. Between the two sites, Rabnabad channel was found more suitable for the sea port. The selection was based on weighted scoring system. The best suitable alignment for an approach channel is selected considering dominant current direction, available navigation depth and requirements for capital and maintenance dredging. Planning and design of approach channel and harbor were carried out considering 9m draft vessel. Although some negative impacts were identified in the study, proper mitigation measures were Assessment of the impact of anticipated suggested to address them. The sea port study was found environment friendly, socially acceptable and external drivers of change on water economically viable. resources in the coastal zone

1919 Coastal polder improvement in the changing climate

The coastal embankment system has been gradually built during the last 50 years for intensification of agriculture and socio-economic development of coastal area. The embankments were designed with no regard to cyclone surges, and very little regard to waves. Crest height of the Marine-drive road in Cox's Bazar embankments was determined as "the maximum normal high tide" (as recorded during 1960-1968) plus a freeboard of 5 feet. Coastal hydraulics and morphological study and design of protection measures for In the Coastal Embankment Improvement Project (CEIP- marine-drive road in Cox's Bazar 2012) of BWDB, the design crest level and side slope of embankment for selected 17 polders were established considering storm surge level of 25 year return period, In order to improve regional connectivity, fishing monsoon water level of 25 year return period, freeboard activities, tourism and socio-economic development allowing 5 l/m/s overtopping, sea level rise, increase of Marine-drive road was constructed from Cox's Bazar precipitation and wind speed in the changing climate and to Shilkhali in two phases. Since commencement of land subsidence. this project, few locations of the Marine-drive road were damaged due to sea wave action. Road & All 139 polders are not exposed to cyclonic storm surges, Highways Department entrusted IWM along with some interior polders are susceptible to overtopping by BUET, DHI (Denmark) and EML (Sri Lanka) to devise a monsoon water level. Considering this fact, sea facing long-term erosion protection measures. polders are designed considering storm surge level and interior polder based on monsoon water level. Resilience of the present drainage system of polders against climate change was assessed and adaptive measures were devised and suggested for implementations. Bangladesh Water Development Board has under taken a project for implementing climate resilient measures for 17 coastal polders.

The main knowledge gap is to know the response of the puerperal rivers and sediment distribution in the coastal area in the changing climate.
