Q#3) What are various water efficiencies when applied and diverted for a field of crops

Q.5. Floods in a stream have the mean 600 m3/s and the standard deviation 400 m3/s. Pleaseanswer the following questions assuming normal distribution.a) What is the probability that the flood flow any year exceeds 700 m3/s?b) What is the 100-year flood discharge?

A hydraulic jump takes place in a rectangular channel downstream of a spillway. The flow in the channel is Q =900 cfs. The conjugate depth (y1) upstream of the jump was measured at 1.4 feet. The channel width is B = 15feet.   (a) Compute the conjugate depth y2 downstream of the hydraulic jump.(b) What type of jump are we looking at in this problem? Refer to the five types presented (in the figureabove) by Prof. Ven Te Chow, the father of watershed hydraulics and physical hydrology.(c) Evaluate the specific energies E1 and E2 at points 1 and 2 (upstream and downstream of the jump,respectively) and the specific energy Ec corresponding to the critical depth yc. Then annotate thespecific energy diagram below with the values of y1, y2, yc, E1, E2, and Ec.(d) How much is the head loss in the hydraulic jump? Explain your answer.

A catchment area is undergoing a prolonged rainless period. The discharge of the stream draining it is 4100 m3/min after ten days without rain, and 1200 m3/min after one month without rain. Find:a. The equation of depletion curve.b. Estimate the discharge after a period of four months, and a period of six months without rain.c. Draw depletion curve to scale

Please do not repost previous solutions given for this question! Will upvote if correct solution is given with calculations 3. Determine the 100 year flow of a 70 square mile watershed in Region 12 of Arizona at an elevation of 3500 feet. Comment on its accuracy, that is what are the upper and lower error estimates in terms of cubic feet per second.

A catchment area of 150 km2 received 150 cm of rainfall in a year. At the outlet of the catchment, the flow in the stream draining the catchment was found to have an average rate of (i) 2.0 m3/s for 3 months, (ii) 3.02 m3/s for 6 months, and (iii) 5.02 m3/s for 3 months. (a) What is the runoff coefficient of the catchment? (ii) If the afforestation of the catchment reduces the runoff coefficient to 0.35, what is the increase in the abstraction from precipitation due to infiltration, evaporation and transpiration for the same annual rainfall of 150 cm? please convert in m/s

Probability plotA bridge will be built over the Meherrin River near the site that the discharge measurements were taken for the log-normal probability plot below. The service life of the bridge is 40 years. If a design discharge of 23,000 cfs is used for the bridge: (a) what is the probability that the bridge will be flooded in any one year? (b) What is the probability that the bridge will be flooded at least once over its service life? (Note: just focus on the “theoretical line” in the plot)
