Steady/Unsteady Flow Through Small Earthfill Dams

Open access


Small earthfill dams, without permanent water storage, are simple operation constructions without any outlet operation or control systems, and which provide water storage in flood wave periods. From the seepage point of view, these simple constructions have a specific complex behavior. Even if generally the body of the dam can be considered to be homogeneous, infiltration through partially saturated materials is unsteady. The water level rapidly increases from the minimum to the maximum level as the water storage volume is relatively low.
