Abstract: Non-Darcy flow conditions can develop for flow over a rockfill dam with a wide profile (e.g., a high rockfill dam under construction in a flood period), flow in gravel river reaches, and overland flow. Non-Darcy flow can ...

Abstract: This paper describes a synthesis of various studies on non-Darcy flow in rockfill material. Based on pipe theory and Taylor's (1948) definition for mean hydraulics radius in rockfill material, theoretical relationships ...
