1- Discuss the effect of both recession and advance curves on the inigation uniformity in surface irrigation 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 22 minutes, and for the 2nd 60 m is 40 minutes, find the time required to cover the 3rd 60 of the irrigation run. 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 the water 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 like sprinkler irrigation and trickle irrigation is important to improve irrigation management.
