Consider a prismatic trapezoidal channel carrying a discharge of 40m³/s. The channel is lined in concrete with a roughness coefficient 0.014. The channel has 2 different segments with a slope of 0.4% along the first 1000m and a slope of 1% along the following 500m. The trapezoidal channel is prismatic and the geometry of the transversal cross section at the station 2500 is presented in the figure below.

Review the lectures that correspond to the analysis of Gradually Varied Flow (Theory and solved problems) 2. Estimate the critical depth of flow at the reference station 2500 and the normal depth upstream and downstream of this station. 3. Identify the type of water surface profile (slope and zone) and the flow regime for the flow depth at the cross sections located 100 m upstream and 100m downstream of the reference cross section (2500 m). 4. Using the direct step method compute the distance at which you will find the normal depth of flow upstream and downstream of the station 2500. Use at least three uniform segments upstream (yo, y₁, y2, Y3) and two uniform segments downstream (yo, y₁, y₂) for the calculation. 5. Using the standard step method estimate the depth of flow 100 m upstream and 100m downstream of the station 2500. 6. Repeat the example worked in class for Culvert Design, using 3 ft diameter round corrugated metal pipe culvert with an n=0.024. Determine the minimum number of culvert barrels needed to convey the flow without compromising the road. 7. The mean annual and the maximum daily runoff are given in the Table. The values were estimated at a river cross section for a 30-year time period. a. Fit and plot the log-Pearson distribution for the peak flow discharge (include observed values). b. Determine the exceedance probability associated to a flow discharge of 750 m³/s Consider a prismatic trapezoidal channel carrying a discharge of 40m³/s.
