A case study of the river training work of Padma river: Assessment of local slope protection measures

Authors: Md. Enayet Chowdhury, Ahmed Hossain, Hussain Muhammad Muktadir


This study aspires to represent a wholesome advertence on the River Training Work (RTW) of Padma River (Bangladesh) based on an in-situ observation, scrutinizing the process weighing it against various river slope protection criteria. Geotextile bags and Cement Concrete (CC) blocking are the main features for slope protection in this project where selection of proper gradation of fine aggregate (to be used inside the bags, D50>O90), selection of coarse aggregate and fine aggregate to be used for CC Blocking, proper placement of geotextile bags and CC blocks along the slope with varying depth from the river bank are important parameters to be fulfilled with respect to Standard C.F values. Based on the sieve analysis and Atterberg limit test, identification of fine sand (to be used inside the bags) and river bank soil type was made respectively. A mathematical model is used to observe the stability of slope using these slope protection measures against adverse embankment failure. The result shows the methodology adopted by Bangladesh Water Development Board (BWDB) partially meets the standard criteria for river bank protection (when wave velocity ≤3ms-1).
