A catchment area of 150km 2 received a 150 cm of rainfall in a year. At theoutlet of the catchment the flow in the stream draining the catchment wasfound to have an average rate of 2.0m 3 /s for 3 months, 3.02.0m 3 /s for 6months and 5.02.0m 3 /s for 3 months. (a) what is the runoff coefficient of thecatchment? (b) If the afforestation of the catchment reduces the runoffcoefficient to 0.50, what is the increase in the abstraction from precipitationdue to infiltration, evaporation and transpiration, for the same annual rainfallof 150 cm.
Answer these both questions a. The total observed runoff volume during a 4 hr storm with uniform intensity of 2.8cm/hr is 25.2 x106 m3 from basin of 280km2 area. What is the average infiltration rate for the area. b. A volume of 3x106 m3 of groundwater was pumped out from unconfined aquifer uniformly over an area of 5 km2. The pumping lowered the water table from 102 to 99m. The specific yield of the aquifer is?
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.
A lake with a surface area of 3,250 acres was monitored over a period. During a three-monthperiod, the inflow was 52 cfs, the outflow was 41 cfs, and 5.25 in. of seepage loss was measured.During this same time period, the total precipitation recorded was 7.25 in. and evaporation losswas estimated to be 4.5 in. Estimate the change in storage for this lake during the time period,in inches
Subject: Hydrology Give me right solution Determine the 10-year period peak runoff for 80 hectare watershed having a runoff coefficient of 0.4. The maximum length of flow of water is 610 meters and the fall along this path is 6.0 meters. The rainfall intensity for that return period is 101.25 mm/hr having duration equal to the time of concentration.

Calculate the runoff from a watershed of (0.01 x 4737) ha. The following data are available: Depth of rainfall is 100 mm. Antecedent rainfall condition, AMC 1: Row crop, good condition in 40 ha (Soil group C) Woodland, good condition in 20 ha (Soil group B) The day after the rainfall of 100 mm, another rainfall of 50 mm occurred. Solve for the surface runoff from the watershed. [ NOTE: Where R is the last four digits of your Registration Number. R = 4737 ]
