Runoff and soil loss as affected by land use, rainfall intensity and antecedent soil moisture under simulated rainfall conditions

摘要

Soil erosion is a severe problem in the world because of its threat to agricultural productivity and off-site effects through pollution and sedimentation. The major factors affecting the soil erosion are rainfall erosivity, soil erodibility, land slope and extent and nature of plant cover. Appropriate land use is the foremost consideration in soil erosion management. The adverse effects of inappropriate land use are more severe in harsh than in moderate climates (Lal 1990).
