1- Discuss the effect of both recession and advance curves on the inigation uniformity in surfaceirrigation system.2- Do you favorite that advance curve and recession curve are in parallel? Explain your answer.3- An irrigation run has a 180 m length. If the advance time for the 1st 60 m of the Inigation run is 22minutes, and for the 2nd 60 m is 40 minutes, find the time required to cover the 3rd 60 of the irrigationrun.4-for the same problem above, if the infiltration depth equation is:D=8r. Find: A- the depth at the beginning of that imigation run at the time that just reaching thewater to the run end, (180 m)Write the advantages and disadvantages of surface irrigation.Discuss the evaluation factors of irrigation, and explain why the moderate imigation systems likesprinkler irrigation and trickle irrigation is important to improve irrigation management.

: Water flows over a smooth submerged object in a channel of width 1.2 m. The water depth upstream of the object is 2.2 m and the water depth downstream is 0.5 m. i) Use the Bernoulli and Continuity equations to calculate the discharge within the channel, and sketch the energy grade line and hydraulic grade line for this problem. ii) The measured discharge in the channel is 2.4 m³/s. Calculate the discharge coefficient, and describe what this physically represents. iii) A pitot tube (or stagnation tube) is placed in the downstream part of the channel, where the water depth is 0.5 m. Calculate the height to which water will rise within this pitot tube (above the depth of water in the channel).
