You have plotted the stream profile of a rural catchment and determined the area the under the steam profile as 1,500 m². What is the equal area ordinate (m) if the length of the stream is 2.5 km? Write your answer correct to two decimal places.

The reservoir's water flow traverses a 15-meter-long spillway, lowering the water's height from 83 meters to 81.5 meters, with the crest elevation at 80 meters, in 30 minutes. Apply C = 1.84. A) What is the reservoir's area?B) How long does it take to extract water from an elevation of 83 m/80.2 m? C) After 20 minutes, what is the water's ultimate elevation?

answer is given just give the solution and right answer.

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.
