MODEL STUDY OF RESERVOIR RIPRAP STABILITY

Etienne P.D. Mansard, Michael H. Davies, Octave Caron

Abstract


A series of large scale (1:15) experiments have been undertaken to assist the Societe d'Energie de la Baie James (SEBJ) in the development of new design guidelines for riprap. The stability of revetments resting on 1:1.8 and 1:2.25 (V:H) slopes is considered. In an attempt to quantify the relative roles of stone size, gradation and armour layer thickness, these tests were undertaken with stone gradations varying from (Mmax/Mmin ranging from 1 to 10) and with armour layers both 2.2Dn50 and 2.7Dn50 thick.
