Abstract

Irrigation erosion and subsequent sediment losses to rivers and
streams continue to be serious problems confronting irrigated agriculture.
The seriousness of these problems depends upon user concerns which in turn
depend upon geographic area and populations. Erosion problems are less severe
in California than in Idaho, but the concern for controlling water quality can
be greater in parts of California because of subsequent water uses. Basin
irrigating rice can reduce suspended sediment loads in water because the basins
serve as sediment retention basins. Furrow erosion causes significant suspended
sediment loads in return flows in California, but the problem is much more
severe in Idaho. Topsoil redistribution by furrow erosion and sedimentation
has reduced potential crop yields by approximately 25%. Several sediment loss
control practices have been developed and evaluated, and are effective, but
costs deter their application. Research is presently directed toward controlling
erosion along irrigation furrows. Methods to increase soil cohesion and utilize
residues in minimum tillage and no-till systems have high potential for
controlling erosion and sediment loss during the next decade.
