Document Summary
Propeller current meter, electromagnetic current meter (ecm), acoustic doppler velocimeter (adv), acoustic doppler current profiler (adcp) More accurate than rectangular weirs for low discharges. By using energy equation: yg : gate opening; cc : for vertical gate: 0. 61, and for radial gate: Lecture 14: initiation of motion of sediments. , then particles move: stabilization of channels. 2. 3 calculate the required grain size to cover the channel. Cvg 3116 hydraulics: design of stable trapezoidal channels. Multiply qs by the channel width (b) to get the sediment discharge. Cvg 3116 hydraulics gb is mass bed load per unit width per unit time (kg/m/s) Ss is the sediment specific gravity (~ 2. 65) ks=3d90, is the depth averaged water velocity, and y is the flow depth. Calculate fgr where dm=a/b (i. e. area/ top width), v is the depth averaged water velocity. Multiply qs by b to get the total sediment discharge.
