Abstract
Majuli, the largest inhabited riverine island of world has been facing a major problem of soil erosion. The current research study attempts to estimate potential soil erosion rates of Majuli by applying Revised Universal Soil Loss Equation Model in addition to other important factors of soil erosion. The mean annual soil loss of Majuli is found to be 268.75 t ha-1 yr-1 with total potential soil loss of 0 to 806.66 t ha-1 yr -1. Ujjani Majuli physiographic region had the highest mean annual soil loss of 312.71 t ha-1 yr -1. By severity, 27.41% of area had recorded highest rate of soil erosion of >357 t ha-1 yr -1. Appropriate use of soil erosion information generated in RUSLE model can help to design suitable land management practices and also improve earlier ones to control and reduce soil erosion in Majuli.
