River bank erosion risk with regards to rainfall erosivity

A fast flowing river erodes its banks more seriously than the slow flowing one. With higher velocity and discharge, the river bank erosion risk potential increases and this affects its sediment carrying capacity too. Rainfall impact to a river will significantly force it to overflow to the bank. The rainfall erosivity and the flowing water have been the prime governing factors in causing erosion. The aim of this study is to evaluate the degree of rainfall erosiveness at Hulu Langat district of Langat River, Selangor, Malaysia and this valuable information would certainly enable the concerned government and private authorities to plan, design and construct the most suitable preventive measures in preventing the river bank erosion
