Consider The Overflow Spillway Shown In Figure The Design Spillway Discharge Is Computed As Q 210 M S The Total Crest 1 (46.14 KiB) Viewed 20 times

Consider the overflow spillway shown in figure. The design spillway discharge is computed as Q=210 m/s. The total crest length of the spillway is 10 m. The approach channel stilling basin and downstream section are of rectangular cross-section having 10 m. There are two rounded nosed piers, each one-meter thick. Headwalls of rounded abutments makes angle less than 45 with the flow direction. Ignoring the head losses over the spillway and over a possible downstream end sill, determine: a) The design spillway head; b) The required lowering of the tiver bed for the stilling basin; and c) The type and dimensions of the stilling basin. 118 m f 113 m 108 m 108 m
