Sedimentation, flow velocity and discharge data from coastal rivers in Southwest Bangladesh

Bangladesh’s Delta Plan 2100 identified river sedimentation and associated water-logging as one of Coastal Bangladesh’s main water security issues. 1.3 million people in Coastal Bangladesh have been impacted by severe waterlogging since the early 1990s, restricting key livelihood activities, reducing agricultural yields, and affecting drinking water quality. As part of the REACH programme, a research team from the Bangladesh University of Engineering and Technology and the Bangladesh Water Development Board (BWDB) have characterized hydrodynamic processes and sediment transport dynamics in the area, with potential implications for different types of interventions. This dataset comprises the measurements of suspended sediment concentration, flow velocity and discharge along a 70km reach of the Hari-Ghengrail-Sibsa river system in Southwest Bangladesh that were used in this analysis. The data is in 3 Excel files Sediment data_Saif_PhD_Bangladesh; Flow_velocity_Saif_PhD_Bangladesh and Discharge_Saif_PhD_Bangladesh. The location of the data collection points is provided in the form of GIS Shape files.
