Two-Dimensional Watershed-Scale Erosion Modeling With CASC2D

Abstract

Erosion is as ancient as our planet itself (or even older) and its role in shaping the earth’s surface and human history and development cannot be over-emphasized. In most inhabited regions of the world, erosion due to human activities is a significant issue affecting water quality, reservoir capacity, biodiversity, and agricultural sustainability. The scientific knowledge of factors that cause erosion is incomplete. Current models for predicting of the future impact of land surface activities on erosion are inadequate. There is a pressing need to develop erosion models that preserve spatial relations between watershed characteristics, rainfall, and factors that affect erosion.
