Abstract
Soil erosion and accompanying sedimentation in the downstream areas are a continuing threat to the worlds land and water resources. Erosion is a serious problem of agricultural lands over a large part of Sri Linka. It is particularly acute on gentle to steeply sloping lands of the wet zone of the Island there the average annual rainfall exceeds 250Omm. Hasselo and Sikurajnpathy (6) estimated an average soil loss of 247 tons per hectare during a tee replanting period of years in the up-country tea estates. Department of Miner Expert Crops (3) reported that soils in majority of marginal ten and rubber estates were eroded and the land capability was poor. The importance of soil erosion in relation to loss of soil and productivity, sedimentation of streams find reservoirs and pollution of natural Waters needs no emphasis. There is an urgent need to unrest the rapid degradation of vulnerable agricultural lands and rehabilitate them through appropriate soil conservation measures.
