【 摘 要 】

Problem statement: Embankment failure and riverbank erosion are common problem inBangladesh. Almost every year earthen embankments and riverbanks are facing problems like erosion,breaching or retirements. Among many reasons the major causes are considered due to the use ofgeotechnically unstable materials, improper method of construction, seepage and sliding. In this study theproblem is considered geotechnical point of view where the geotechnical properties of failed Jamuna riverembankment material and Padma riverbank material were investigated. Moreover, stability analysistechnique of embankment has been reviewed through a case study of Manu river embankement.Approach: Sample materials were collected during field investigation and tested at laboratory according toJapanese Industrial Standard (JIS). Limit equilibrium stability analysis and steady state seepage analysiswas conducted for Manu river embankment to review the existing design procedure of embankment.Results: Study results reveal that the soil of Jamuna river embankment is not well graded sand and thepermeability is found minimum of 1.29
