- The Chezy coefficient is 80 for flow in a rectangular channel that has a width of 3 m and normal depth of 1.5 m. What is the velocity in the channel if the bottom slope is 0.016? a. 2.19 m/s b. 7.16 m/s c. 8.76 m/s d. 39.44 m/s4. A river stage is readily measured by reading a USGS stream gage placed in the riverbed. During a storm event, the stage can be measured directly. From this, a discharge hydrograph can be inferred.The following stage levels were measured during a storm event: Analysis of this river revealed adischarge-stage correlation of Q = 12.43h2.658, where Q = discharge (m3/s) and h = stage (m).Provide both a stage hydrograph and a discharge hydrograph for this storm event.Clearly mark all axes and give each graph a title.For the following data on speed and density, determine the parameters of the Greenshields' model (U, Uf, Kj) . Also find the maximum flow and density corresponding to a speed of 30 km/hr.
