As part of a stream restoration project, a design engineer would like to create a nice little area for fish to hide behind. She contracted a 50-foot-wide stream by adding a root wads on one side and a large rock on the other sideof the stream. Both the root wad and the large rock take up 10 feet on each side of the existing stream and can be assumed that they form a 90-degree vertical wall on either side of the stream.The total approaching flows in the stream are 380 cfs where the impeded flows normal to the root wad and the large rock are 20% of the total flow on each side. The average depth of the approach section is 2 feet. A surveywas completed, and the Kinetic Energy Coefficient was found to be 3.0.Determine the backwater due to the stream restoration efforts

According to given Data A 50-foot-wide stream by adding a root wads on one side and a large rock on the other side of the stream.Both the root wad and the large rock take up 10 feet on each side of the existing stream The total approaching flows in the stream are 380 cfs where the impeded flows normal to the root wad and the large rock are 20% of the total flow on each side. The average depth of the approach section is 2 feet. A survey was completed, and the Kinetic Energy Coefficient was found to be 3.0. To, Determine the backwater due to the stream restoration effortsThe backwater due to the stream restoration efforts can be calculated using the formula: Backwater = (K * (Q^2)) / (2 * g * B * h) where K is the Kinetic Energy Coefficient,Q is the total flow, (q=380)g is the gravitational constant, (g=9.81)B is the total width of the stream, and (B=50)h is the average depth of the stream. (h=2) Therefore, the backwater due to the stream restoration efforts is: Backwater = (3.0 * (380^2)) / (2 * 9.81 * 50 * 2) = 223.3 feet ( Answer)

A rill channel is observed at two locations during a storm, 20 and 60 m from the top of the hill. The slopes are 5 and 4 percent, the rill widths are 150 and 220 mm, and the hydraulic radii are estimated to be 01 and 0.04 m, respectively. The sediment transport rate is measured and found to be 200 and 800 kg/m-s. The rill erodibility (Kr) is estimated to be 0.004 s/m, critical shear (τc) 2.5 Pa, and transport coefficient (B) 100. Calculate the sediment transport capacity and erosion rate for each position. Show complete solution.

As a result of the construction of a 4 m high bridge over a rectangular stream with a width of 8.6 m, the width of the stream under the bridge decreases to 5.8 m. In case of a flood flow of 132 m3/s in this stream, the roughness value of the Stream Manning was determined as 0.014 and the slope as 0.011. a. Calculate the uniform water height and regime of the flood current. b. Determine whether the bridge will be submerged as a result of the flood current.

The figure is a plan view of a confined aquifer showing two contaminated zones, 1 and 2. The aquifer has a saturated thickness of 80 ft, hydraulic conductivity of 42 ft/d, and the regional hydraulic gradient is 0.0075 from right to left as shown. A pumping well with a flow rate of 170 gpm is planned to run continuously at the location shown, and form a stable (equilibrium) capture zone.

A 927-acre catchment has been monitored for many years. It has been found that the average annual rainfall over the catchment is 37 inch and that the average streamflow is 1.0 cfs. Geologic investigations reveal a bedrock underlying the catchment that effectively prevents any deep seepage or groundwater recharge. Estimate the average annual evapotranspiration in inches for this catchment.
