The Marine-drive road project connecting Cox's Bazaar with Teknaf began in 1993-94; Phase-I of the road from Kalatoli to Inani (24 km) was completed in 2008. In Phase-II, another 24 km road extending Inani to Shilkhali is under construction from July 2008 and is scheduled to be completed by 2013. The project has been taken to facilitate tourism, regional connectivity and fishing activities. Since commencement of the project, few locations of the Marine-drive road has been damaged from wave action of sea as reported by the . The Roads & Highways Department commissioned IWM along with BUET, DHI and EML to carry out the study to find a cost effective sustainable solution to the erosion problem. The main objective of the study is to investigate coastal erosion processes along the Marine-drive road, review existing protective measures and devise immediate & long-term mitigation measures. Installation of Workhorse Sentinel ADCP IWM carried out comprehensive survey viz. topography, bathymetry, suspended sediment, bed sample, velocity profiling & level measurements. IWM also deployed Workhorse Sentinel ADCP in the sea, use of first ever such equipment in Bangladesh to collect wave height measurements. IWM also carried out analysis on historical bank line changes using satellite images of 1974, 1980, 1989, 2000 and 2012 to indentify vulnerable locations and shifting characteristics of shoreline in Phase-I & Phase-II of the project area. Monitoring surveys at vulnerable locations were carried out 4 times in 2012 and 2 times in 2013 to analyze & assess changes in near bank slope in vulnerable areas and erosion- deposition pattern. Based on these monitoring data IWM Temporary Protective Works Along The Marine Drive Road provided an immediate temporary protection design in Situation in specific locations are extremely severe and subjected to consultation with BUET for the vulnerable locations. severe shoreline erosion. Considering existing situation it is urgent The modelling work is continuing in consultation with DHI to devise immediate protective measures against shoreline erosion. experts and selection of proper protective works and design The Bangladesh Army successfully used geo-bags as immediate is being carried out by IWM and BUET in consultation with measure to protect the marine drive road from erosion however, an experts from DHI and EML.

Data Collection & Bathymetric Survey using ADCP for Regional Cooperation and Integration Project (RCIP)

A Joint Communiqué was signed in 2010 between the Government of Bangladesh and India in connection with sub- regional and Trans-Asian Railway (TAR) connectivity with assistance from ADB. Under the project, the RCIP, Rail Component, involves design of new or upgraded railway crossings over number of major rivers. In this regards, hydro- technical investigations are being undertaken to derive hydraulic design parameters for rail bridge crossings of major waterways, establishing river training works and bank protection requirements. To support the design works through field investigations, CANARAIL Consultants Inc. of Canada requested Institute of Water Modeling (IWM) to undertake and document river bathymetry, bank line location & topography and flow characteristics using RTK GPS. The survey was done in the Modhumati, Arial Khan, Dhaleswari, Buriganga and Gumti River. Under the program, IWM successfully completed field data ADCP observation using RTK-GPS in the Dhaleswari River collection activities in August and September, 2013.

02 Hydro-geological Investigations & Groundwater Modelling for the Northern Part of the Barapukuria Coal Mine Basin Area

The Barapukuria Coal Mine in Dinajpur district in North-West Bangladesh is the only underground coal mine in Bangladesh. The coal deposits is underlain by a thick water bearing strata (Aquifer; Avg 107 m) . The coal reserve was discovered by Geological Survey of Bangladesh (GSB) in 1985. The U.K. based firm "MIS Wardell Armstrong" and China based organization "China National Machinery Import and Export Corporation (CMC) carried out some feasibility study in Barapukuria area and confirmed about 390 MMT reserve of coal in an area of 6.68 sq kms. The quality of

Barapukuria coal is also better compared to imported coals. Barapukuria Thermal Power Plant This gives Barapukuria coal competitive advantage over imported coals. Barapukuria coal is also low in ash and Barapukuria Coal Mine Area extremely low in Sulphur content which meets international Phulbari Coal Mine Area environmental standards. On completion of supplementary INDIA geological survey and basic design of the mine by CMC and approval by Petrobangla, physical works of the project commenced on 1st June 1996.

The present underground mining area covers the central 3 sq Dighipara Coal Mine Area km out of 6.68 sq km reserve area. No coal extraction is carried out from Northern 2.81 sq km (Reserve 135 MMT Approx.) area where coal exists in relatively shallow depth.

On the other hand, there will be a noticeable increase in PA-1 increases from 1743 Mm3 under base condition to in post monsoon recharge under climate change condition 1815 Mm3 and 1860 Mm3 in 2030 and 2050 respectively. compared to the base case. In PA-2 it increases from 304 Mm3 under base condition to 327 Mm3 and 319 Mm3 in 2030 and 2050 respectively. Availability of surface water resources were assessed at the upstream and downstream chainage of 4 major rivers, and were found to have sufficient flows. Surface water salinity remains below 1.0 ppt in 3 rivers namely Biskhali, Bureswar and Tetulia. However at downstream of Baleswar river, salinity becomes more than 1.0 ppt during dry seasons and reaches to about 6.5 ppt maximum. Under average hydrological conditions, potential groundwater recharge in PA -1 varies from 183 mm to 291mm and in PA -2 it varies from 396 mm to 522 mm. In PA -1, during dry season GW salinity remains below 1.0 ppt only in a small part of Bamna, Amtali and Kalapara upazilas and in rest of the area, salinity remains above 1.0 ppt. In the wet season, the situation noticeably improves. In PA -2, in dry Map Showing : Location of the Pilot Areas Monitoring of Hydraulic & Morphological Conditions of the Jamuna River for Safety of River Training Works of Bangabandhu Bridge for the Period 2013 to 2017

Bangabandhu Bridge is a nationally important structure in Bangladesh built on the mighty river Jamuna. An average 13 kms section of the river discharges 60,000 m3/s which is guided through a 4.8 kms section between 2 Guide Bunds of the bridge; river responses due to the constriction needs to be attended intelligently for safety of the bridge. The Jamuna is one of the world's great rivers, ranking the top three in terms of both sediment & water discharge. The figure on the right shows constriction at the bridge location; variable flow and sediment along with Sirajgonj Hard Point Bhuapur Hard Point upstream condition plays major role in governing morphological processes that can endanger stability of the Guide Bunds and the bridge. In order to protect and face Bangabandhu Bridge adversities, every year before onset of the monsoon, the Bangladesh Bridge Authority (BBA) East Guide Bund adopts preparatory works to update its West Guide Bund monitoring plan with forecast on critical hydraulic & morphological conditions in the vicinity of bridge location and specifically for river training works (RTW) under the framework of preparedness program. The RTWs consists of two Guide Bunds and Bhuapur Hard Point. Figure showing plan form of the Jamuna River

05 Climate Change Impact on Urban Drainage System and Adaptation Measures

It is now commonly accepted that climate change is occurring. For Bangladesh, this means increased variability in rainfall in terms of amount and also frequency (CCC 2006). There is growing evidence that this is already happening with extreme monsoon events (e.g. in Dhaka the heavy rainfall events that occurred in 28th July 2009 and 14th September 2004), which never occurred since records began in 1957 (BWDB, Banani Station). Climate scientists also say that the increased variability in rainfall also means longer drier spells (no rainfall days) in between rain events. Again, there is growing evidence that this is also happening. Often it is heard that monsoon rainfalls does not occur like it used to be earlier - 3 or 4 days of continuous rainfall. The changing rainfall pattern creates challenges for drainage engineers as the system was designed for a different pattern. Performance of drainage system also depends on other factors: solid waste management, sediments blocking drain inlets, wastewater entering drainage pipes, unplanned & uncontrolled urbanization filling up low lands and khals, etc. For a city like Dhaka, the on-the-ground realities create more of an impact than climate change, i.e. local effects can dominate climate change impacts. Despite this notion, it is clear that climate change is going to make existing bad situation worse. IWM has shifted its focus from impacts to adaptation. Advanced mathematical tools, such as MIKE URBAN and MIKE FLOOD, are being tested on their effectiveness of such innovative ideas. IWM is presently looking at outside-the-box solutions, which involve multi-purpose or multi-functionality of infrastructure & land use in urban context; such as, lowering of the Dhopkhola Play ground to act as a "dry pond" which can reduce urban flooding in Old Dhaka area. Presently, important Master Plans for Dhaka are being prepared/ updated. IWM was involved in Wastewater Master Plan, which proposed disconnecting sewerage pipes from drainage system. Also Dhaka Detailed Area Plan (DAP) and Drainage Master Plan (DWASA) are currently being updated. Hence, there are clear opportunities to introduce systematic changes that can markedly improve urban drainage in Dhaka City. Similar opportunities also exist for other urban centres of Bangladesh, e.g. Chittagong, Narayanganj, etc. Expertise of IWM in the area of urban drainage design, modelling & analyses is providing effective support to practitioners (e.g. DWASA) and planners (e.g. NCC) to reduce urban flooding problems. The solutions being proposed are not only robust to the impacts of climate change but are also MIKE Urban Drainage Model of Goranchatbari System, north-west Dhaka. cost effective, socially acceptable and environmentally friendly.

06 Master Plan for Water Supply & Sewerage System of Dhaka

Dhaka city's water supply source's pattern is conjunctive use of groundwater & surface water. In order to decrease the 5,453 24.53 dependency on ground water Dhaka WASA is planning to 5,000 25 harness surface water from the Rivers Padma and Meghna. To 4,573 improve efficiency and minimize loss of water DWASA is 19.65 4,000 20 establishing District Metered Areas (DMA)'s.

As a part of the project 1,000 5 IWM has undertaken a comprehensive assessment of existing situation, developed strategies with stakeholder consultation 0 0 and devised short-term, medium term and long term plan. 2011 2015 2020 2025 2030 2035 Residential Slum Other Fire Fighting Loss population The final recommendation will include financial analysis of the proposed developments, organizational structure, policy Water Demand and Production Requirement for Dhaka City and regulatory framework, water rates, operation and maintenance and strategic environmental assessment.

In order to provide sufficient sanitation coverage in Dhaka City, DWASA undertook the sewerage master plan project at Banasri SPS the same period. The plan had a design horizon up to year 2035. The design of infrastructure for priority investments included rehabilitation of the trunk sewer, collection sewer in Gulshan, Banani localities, 4 pump stations along the trunk main and augmentation of Pagla STP. The priority investments are earmarked for the first phase of the Master Plan (2013 - 2015). Together with Grontmij A/S of Denmark, IWM worked towards a decentralized, equitable master plan. The master plan introduced trickling filter technology of wastewater treatment for its simplicity and low cost operation and maintenance. Sewer model was developed the first time for Dhaka City and IWM independently designed 120 km length of sewer collection pipe network using SewerGEMS for different localities of Dhaka.
