Padma Multipurpose Bridge Project

ProjectComponentsConstructionYardLeft Bank (Mawa)This CY1 in Mawa side is agri-charland,separated with the mainland by a narrowshallow channel at Vill. Kumarbhog.Agriculture crops such as paddy (roppa)and peanut are cultivated on thisCharland. It is a stable and floodplain charand not submerged during normal flood.Only during high floods (1988, 1998, and2004 floods), this char is submerged at thewater depth of about 1.5m. Nosettlements, water bodies, and trees arelocated on this Charland.Right Bank (Janjira)plantations. There are several waterbodies (such as Rivers, khals andponds) that cross the RTW area. Anumber of cultural institutes such asschool, mosque, eidgah, familygraveyard etc are located within the300m of RTW. Two ferry ghats(Kewrakandi and Kathalbari) andseveral boat ghats are also there withinRTW area.CY2 in Janjira side is located at d/s ofthe RTWs at Painpara, Naodoba Mouzain Upazila: Janjira, District: Shariatpur.CY2 is located at about 400m from theMazirkandi Ferryghat-Shariatpur Roadtowards west. It is mainly agriculturebased area and fertile. It is an unstablefloodplain and not submerged duringnormal flood. Only during high floods(1988, 1998, and 2004 floods) this areais submerged at the water depth ofabout 1m. Almost every year, this areais eroded by the Padma River at the rateof about 100m. Many homesteads(about 1000 households), water bodies(mainly fish ponds) and homesteadtrees (mainly mango, coconut, palm,papaya, guava, cotton tree, koroi,shegun, mehegoni as well as bananaand bamboo bushes are located withinthis area.3.1.4 Climate23. The Project area is located in a typical monsoon climate with three main seasons, summer(March to May), monsoon (June to October) and winter (November to February). The summer isgenerally hot with occasional moderate to heavy rainfall. The Monsoon is generally humid with 80% ofannual rainfall. The winter is generally cold with less humidity. Meteorological stations (of BangladeshMeteorological Department, BMD) located closest to the Project areas are: Dhaka (42 km from leftbank on north-eastern side) and Madaripur (35 km from right bank on southern side). Weather datafrom these two stations is collected from 2005 to 2008.24. Temperature: Mean monthly rainfall data of Dhaka and Madaripur stations are given inFigure 3-8 and Figure 3-9, respectively. December and January are the coldest months with averagemonthly temperature of about 18 0 C, while April to September are the hottest months with averagemonthly temperatures ranging from 28 to 30 0 C. The maximum daily temperatures recorded at Dhakaare 38.5C and at Madaripur is 39.5C. The minimum daily temperatures recorded at Dhaka are9.6 0 C and at Madaripur is 9.3 0 C.25. Rainfall: Annual rainfall of the Dhaka varies from 1,991 to 2,885 mm, while the annualrainfall of Madaripur varies from 1,503 to 2,061 mm during 2004 to 2008. June to October is therainfall season. Monthly rainfall data of Dhaka and Madaripur are given in Figure 3-10 and Figure3-11, respectively. July is the wettest month with monthly rainfall of 331 to 753 mm at Dhaka, and 223to 556 mm at Madaripur. December is the driest period with almost no rainfall. Maximum daily rainfallrecorded at Dhaka is 190 mm (September 2008) and in Madaripur is 150 mm (September 2006).3-11
