Subject: irrigation engineering a) What is field capacity and derive its relationship with water depth? b) Compare optimum moisture content with wilting point water content?
Monthly potential evapotranspiration (ET) rates Up and measured precipitation depths P in a basin are given below. It is assumed that the soil moisture is at the wilting point in the beginning of January is 80 mm. The soil can hold a maximum moisture of 80 mm until it reaches the field capacity. January U. = 12 mm P= 56 mm February U. = 8 mm P= 72 mm March U = 52 mm P= 192 mm April U = 102 mm P= 38 mm What is Runoff in March?
A stream of 135 L/s was diverted from a canal and 100 L/s were delivered to the field. An area of 1.6hectares was irrigated in 8 hours. The effective depth of root zone was 1.8 m. the runoff loss in the fieldwas 432 m3. The depth of water penetration varied linearly from 1.8 m at the head end of the field to1.2 m at the tail end. Available moisture holding capacity of the soil is 20 cm per meter depth of soil.Irrigation was started at a moisture extraction level of 50 percent of the available moisture. Determine;a. The water conveyance efficiencyb. The water application efficiencyc. The water storage efficiencyd. The water distribution efficiency

A recently irrigated field plots on Day 1 the total available soil moisture at its maximum value of 17 cm. If the reference crop evapotranspiration is 4 mm/day, calculate the actual evapotranspiration at Day 1, Day 4 and Day 6. Assume soil water depletion factor of p=0.20 and crop factor of K = 0.80.
Problem #2: A 700,000 m2 watershed is 30 percent Agricultural and 70 % urban. The agricultural land is 40 % cultivated with conservation treatment, 35 % meadow in good condition, and 25 % forest land with good cover. The urban area is residential: 60 % on 1350 m2 lots, 25 % on 1000 m2 lots, and 15 % streets and roads with curbs and storm sewers. The soil group is B. Determine a composite CN and the total discharge from a 150 mm for 24- hour storm duration.
