A catchment has the Horton infiltration parameters: fo= 150 mm/h, fc = 50 mm/h, and k = 3 min¹. The design storm is given below. Estimate the time when ponding begins. Interval (min) Average rainfall (mm/hr) 20 40 80 170 90 20 0-10 10-20 20-30 30-40 40-50 50-60
Estimate the constant flow rate of withdrawal from a 15 km² reservoir in a month (30days) during which the reservoir level dropped by 1 m despite an average inflow into the reservoir of 0.95 * 10 m³ /day. During the month, the average seepage loss from the reservoir was 4.5cm, the total precipitation on the reservoir was 19.5cm, and the total evaporation was 7.5cm.

Question- A peak flow of a flood hydrograph due to a 6 hour storm is 470 m³/s. The corresponding average depth of rainfall is 8 cm. Assume an Infiltration loss of 0.25 cm/hour and a constant base flow of 15 m³/s. What is the peak discharge of 6 hour unit hydrograph for this Catchment?
2. You're designing a stilling basin and you need to know the minimum length of that basin and also how much energy loss will be achieved before flow is released into the downstream channel. Given the basin width is 10-feet, the flow rate is 240 CFS, the upstream froude number is found from hydraulic modeling to be 4.0. Solve the following: • Minimum length of the stilling basin. • Energy loss within the stilling basin (Calculate both energy loss in feet and in tons). • The depth of water being released outside of the stilling basin. • The Froude Number being released from the Stilling Basin. • Look at USBR Design of Small Dams and Write a paragraph (4-5 sentences) of the recommended stilling basin you would propose for the hydraulic scenario.
Given the earth dam and flow net shown, calculate the seepage loss under the dam if the water height behind the dam is 15ft. The soil has a hydraulic conductivity of 100 ft/year.
