It refers to the composite parts of the irrigation system that divert water from natural bodies of water such as rivers, streams and lakes. My ganitong tanong din sa AE Board Recalled 2012 Answer: Headworks 2. The International Soil Science Society describes sand as a soil particle with a diameter of Answer: 0.02 mm to 2 mm 3. The locus of the elevation to which water will rise in a piezometric tube. Answer: Hydraulic gradient 4. Surface irrigation method where a much smaller area is enclosed by levees Answer: Basin Flooding 5. The ratio of water beneficially used on the project, farm or field to the amount of water delivered to the farm expressed in percent. Answer: Water-use Efficiency 6. The ratio of water stored in the root zone during the irrigation to the water needed in the root zone prior to irrigation, expressed in percent. Answer:Water Storage Efficiency 7. The ratio between water stored in the soil root zone during irrigation and the water delivered to the farm expressed in percent Answer: Water Application Efficiency 8. The ratio between the water delivered to the farm and the water diverted from a river or reservoir expressed in percent. Answer: Water Conveyance Efficiency 9. The sum of total static head, pressure head, velocity head and friction head. Answer: Total Dynamic Head 10. The water is directed to the base of the plant. Water is applied to the soil through small orifices Answer:Drip or Trickle Irrigation 11. The surface is rarely wet since the water is supplied from the soil underneath. This requires complete control of the water table so that the root zone is kept relatively free of excess water but is continually supplied with capillary moisture during the cropping season.hindi ganito ung question,pero my ganitong choices at sagot,basta basahin nyo n lng,marami kasing ganitong question sa type ng irrigation. Answer: sub-irrigation 12. It is accomplished by running water through small channels or furrows while it moves down or across the slope of the field Answer: Furrow irrigation 13. In Earth embankment, on structures less than 15 m high with average materials, the sideslopes should be steeper than_____on the upstream face Answer: 3:1 14. Same above question but on the downstream face. Answer: 2:1 15. Earth embankment question.What is the slope in blankets.eto lang natandaan ko.basta mgbasa na lang kayo about sa earth embankment.

What is the depth of water in a trapezoidal channel with a side slope of 2 and carrying a 2.5 m3/s water flow? The channel’s bottom width is 1.5 meters and the flowing water has a velocity of 0.8 m/s.maraming ganitong question kaya practice nyo na magcompute… 27. Trapezoidal weir computation,given the value of Q, b, s, R,P n,A,v.Find d? 3 question for this problem ang binigay,same ang mga values pero hahanapin m lang yung value ng b or v.kahit d ka na mgcompute,check m na lang sa problem na binigay.. 28. How many sprinklers with spacing of 7m x 7m are needed to irrigate a rectangular piece of land 125 m x 190 m if the laterals are set parallel to the longer side of the field? Answer: 486 29. One thousand two hundred and fifty cubic meters of water was delivered to a 10 ha farm for the month of June in which consumptive use is estimated at 8 mm/day. The effective rainfall for the period was 150 mm. What is the irrigation efficiency? Sample prob na my ganitong katulad na question s 2013 ae board exam.practice nyo na lang icompute yan..2 or 3 same question pero magkakaiba ang mga values na binigay. 30. Given a shallow tubewell with maximum discharge of 15 lps and a total dynamic head of 7 meters. Determine the power rating of the primemover for the pump if pump and primemover efficiencies are 60% and 55%, respectively.2 or 3 questions but different values were given. 31. Determine the irrigation interval for a farm with soil root zone having a field capacity of 200 mm and a wilting point of 105 mm. Assume that the consumptive use for June or August is 7.5 mm/day with

AGRICULTURAL ENGINEERING RECALLED BOARD EXAM QUESTIONS 2013 AREA 2 Soil and Water Conservation ,Irrigation and Drainage and Allied Subjects no rainfall and the allowable moisture depletion is 75%.basta try nyo na lang icompute,my ganitong sample na problem na binigay. 32. The recent monsoon rains have posted a nearly uniform rainfall intensity of 30 mm/hr over a 1,500hectare watershed area in Central Luzon. If the runoff coefficient is 0.15, what is the runoff in 3 m /sec? used the formula Q= CIA 33. Evapotranspiration in an 10 ha farm is 10 mm/day and percolation losses is 5 mm/day. What is the design discharge of a canal to be able to deliver a 5-day requirement of the farm in 24 hours if irrigation efficiency is 75%?2 questions yata ang may ganitong problem ang binigay.d ko sure ung mga values pero ganyan yung binigay na prob…. 34. Computation of Moisture content,given the value of FC ,PWP,AS and Moisture depletion 35. Computation,Given yung formula,pati mga values,substitute nyo na lang,2 to 3 problem,kaso ang hirap palabasin yung mga sagot kasi malilito ka sa mga values at unit na given,kaya try try lang hanggat mapalabas yung result,kung hindi naman, mgwild guess na lang kung saan malapit ung napalabas nyong sagot.basta bahala na kau kung anu like nyong gawin..hehe End Notes:maraming question sa Irrigation and drainage and soil conservation.more on terminologies and values at marami ang computation,maybe more than 50% questions Surveying 36.
