Relationships for Non-Darcy Flow in Rockfill
Publication: Journal of Hydraulic Engineering
Volume 124, Issue 2
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 between friction coefficient and Reynolds number and relationships between hydraulic gradient and bulk seepage velocity have been obtained. The new relationships between hydraulic gradient and bulk velocity are then compared to the various formulas for rockfill available in the literature by computer simulation.
