Sediment carried in furrow irrigation return flows is a large contributor of sediment to
riparian areas in the Pacific Northwest (PNW). About 3.3 million acres are surface irrigated
in Oregon, Washington and Idaho, nearly two million in Idaho alone (Anonymous, 1991).
Furrow irrigation is an inherently erosive process, but sediment losses in the PNW are worsened
by the steeper slopes and high erodibility of typical furrow irrigated fields in the region.
Irrigation-induced erosion is one of the most severe threats to sustainability of agricultural
production in the region.
