Stability Analysis of Riverbank Erosion
Riverbank erosion is a hydraulic process that is caused due to riverbank instability. The erosion process is often observed in alluvial rivers. The mighty river Brahmaputra in Assam, having alluvial riverbanks, is mostly unstable. A comparative study of the stability analysis of different riverbanks in upper Assam including Majuli Island is represented herein. Soil parameters such as grain size analysis, plasticity index, shear parameters, and permeability are studied for the analysis of bank stability and to find the critical angles for each case. Different soil samples are collected from the Dikhow, Dhansiri, and Lohit river banks and are tested in the laboratory to find out the geotechnical and engineering properties. Culman type of stability analysis for steep, homogeneous, and cohesive river banks proposed by Osman and Thorne in 1988 is selected for the study. The analysis is done using the standard formulas that are based on the results obtained from different laboratory tests. Critical bank angles are calculated from the analysis along with the factor of safety. The work can act as a vital keyway for taking the precaution against the failure of the riverbanks and thereby to mitigate flooding in the rainy season.
