Abstract:

Erosion and sedimentation by water includes the process of detachment, movement, and deposition of soil particles (14). Under irrigated conditions, the erosive process is water flowing over soil, either as concentrated flow, or water drops from sprinklers impacting on the soil. This erosion process is similar to rainfall caused-erosion. The purpose of this paper is to: summarize the results of selected studies to show erosion under irrigated conditions can be excessive; provide some indication of the impacts of erosion and sedimentation; summarize some of the significant conclusions reached in these studies; and provide a background for the five other papers on the topic of erosion from irrigated land.
