Abstract

Flood submerges vast areas of Bangladesh every year. To protect agricultural lands and city areas from submergence due to flood, earthen embankments are provided. However, earthen embankments in Bangladesh are subjected to seepage and erosion. To protect embankments from seepage and erosion-Cement Concrete Blocks (CC Blocks) are usually provided. Provision of CC Blocks reduce erosion but cannot prevent seepage completely, which is one of the main causes of failure of earthen embankments in Bangladesh. In this study, five sections of Rajshahi City Protection Embankment (RCPE) are selected which are subjected to seepage and erosion during rainy seasons because they are not properly protected. Seepage analysis using Geo-Studio Software indicates that seepage through RCPE can be prevented completely, if the upstream surface of the embankment is protected by CC Blocks with joints between CC Blocks that are sealed properly.
