Demonstration of earth berms and drop inlet structures
A series of three berms with drop inlet structures leading to a subsurface tile were constructed or improved in the lower end of the Avon River drainage basin during 1981. The purpose of these projects was to demonstrate cost-effective means of controlling soil erosion with minimum interference to the agricultural practices in the area. The structures control rill and gully erosion while causing a portion of the sediment load in the surface runoff to settle out in temporary pounds behind the berms. Landowner acceptance and local reactions have been favourable to the projects. Further surveillance of these structures will reveal the degree to which they have succeeded in controlling soil erosion.
