Abstract

|
|
|
A reservoir located at Chollanam-do province was selected to estimate annual deposition rate, volume of annually deposited material, and annual soil loss from the watershed using Cs-137 redistribution. Sediment profiles of the reservoir indicated an average annual deposition rate of 1.56 ㎝ yr^(-1) and the total deposited volume of 166530 ㎥since 1963/64. Annual soil loss from the watershed was 25 ton ㏊^(-1). Particle size analysis showed that most of the particles were silt-sized ones.
