RELATIONSHIPS FOR NON-DARCY FLOW IN ROCKFILL

This paper describes a synthesis of various studies on non-Darcy flow in rockfill material. Based on pipe theory and Taylor's (1948) definit ion for mean hydraulics radius in rockfill material, theoretical relat ionships between friction coefficient and Reynolds number and relation ships between hydraulic gradient and bulk seepage velocity have been o btained. The new relationships between hydraulic gradient and bulk vel ocity are then compared to the various formulas for rockfill available in the literature by computer simulation.
