Movement and deposition of sediment in the vicinity of debris‐barriers

Abstract

Accelerated erosion and the scour and deposition of sediment in streams have had, in many instances, harmful effects on the use of valley‐floors as residential areas and for farming and grazing. Perhaps the outstanding significance of streams carrying a relatively large sediment‐load is the effect on the silting of large reservoirs, the silting‐rates of which determine not only the life of these reservoirs for flood‐control purposes, but also the perpetuity of agriculture, cities, and industries, which are dependent on the water stored.
