Example Problem Water budget for a lake provides following observations: Precipitation, P = = 43 in./yr. Evaporation, E = 53 in./yr. Inflow to Lake, Qin = 1 in./yr. Outflow from Lake, Qout = 173 in./yr. Change in Lake storage, AS = -2 in./yr. Find the net groundwater flow. Solution: E SWIn GWin PPT Evap SW Out GWout
A discharge of 0.15 cumecs is supplied into a canal at the head and 0.1 cumecs is delivered to field having an area of 1.5 hac. The Irrigation is started at a moisture extraction level of 60% of the available moisture and then extends for 10 hours. Determine the following efficiencies: water conveyance, water application, water storage, and water distribution. The following information are known: effective depth of r.z. = 1.7 m, runoff loss in the field = 425 m3 , water penetration depth varies linearly from 1.7 m at the head end of the field to 1.1 m at the tail end, W.H.C. = 25cm/m depth of soil.
Please answer question 2
QI. (a) Describe the Rational' method of designing surface water drainage systems. Define fully any terms used in the description. Discuss the assumptions made in applying the rational method, and comment upon the procedure used to predict the peak flow for a given return period. (b) At the beginning of the month of June, water level of a reservoir with surface area of 7km? was at 20m (Refer to reservoir characteristic curve in Figure Qla). Average longterm monthly rainfall for the month of June recorded at five raingages is summarized in Table Q1 (assuming the same average amount of rainfall is also recorded in the reservoir). The inflow to the reservoir X, located at the downstream catchment outfall, resulted from that rainfall can be estimated as Qin = 0.65PA where P is mean areal rainfall (to be estimated by Thiessen Polygon) from a 36km? catchment area A, schematically shown in Figure lb. An average monthly withdrawal of 6MCM from the reservoir is required for water supply…
