The feasibility of a sediment trap immediately upstream of the reservoir to trap bed load was examirted. A computer model for transient scour and deposition was used to examine the effects of downstream scour. Several problems were encountered in using this model and its value was in giving an overall impression of where scour would occur for various downstream controls rather than giving absolute depths o scour. 3.2 Transport Relationships Both floods in 1965 included flow at G.S. 006047. Table 1 shows estimated flow volumes at gauging stations. TbIe 1 ESTIMATED FLOW VOLUMES (1965 STORHS) Gauging Station G.S. 006009 G.S. 006046 G. S. 006047 7/3/65 0.83 0.45 0.13 Mm 3 18-19/3/65 0.69 0.51 0.34 It is known flow occured for the 1979 storms at each or the gauging stations G.S. 006009, G.S. 006046, G.S. 006 047, but flow volumes are not yet available.
