WebTable 1. Empirically derived values of the drag coefficient (at 1m above the bed) for different bottom types. From Soulsby 1997. Before use within a depth averaged 2D model, the suggested values of C100 must first be converted to equivalent values of depth averaged Cd. A relatively simple method is Cd = (Mh ) g 1/ 6 2 1 WebHenri Philibert Gaspard Darcy (1805–1858) was a French civil engineer. He performed numerous experiments of flow resistance in pipes ( Darcy 1858) and in open channels (Darcy and Bazin 1865 ), and of seepage flow in porous media ( Darcy 1856). He gave his name to the Darcy-Weisbach friction factor and to the Darcy law in porous media.
