The Horton's infiltration equation for a basin is given by f= 6 + 16e-2t, where 'f' is in mm/hr and tis in hours. What are the values of fo, f and k? If a storm occurs on this basin with an intensity of more than 22 mm/hr, determine the depth of infiltration for first 45 minutes and the average infiltration rate for the first 75 minutes?
If the rain starts at 8.00PM on 10November 2015, use Horton's Equation to solve for the infiltration capacity of the soil (mm per hat 12:30AM the next day. Given the initial infiltration capacity of the soil is 0.0386 cm per min, the time constant as 0.1018 per hour, and the capacity of soit for hrial infiltration is 0.6683 cm per hour. Detailed solution step by step
Q3. It was rained on a basin, where the soil has a k constant of 1.7, an initial infiltration rate of 3.2 mm/hr, and an infiltration rate of 2.3 mm/hr minutes later. The precipitation depths versus time are tabulated below: t, hr 600 615 630 645 700 715 730 745 800 815 80 845 900 915 | ΣΡ, cm 0.0 0.4 2.0 3.8 5.0 5.0 5.0 UH, (m/s)/cm o 10 35 65 85 75 50 35 25 18 12 6. 2 a) Obtain Horton's infiltration equation (10 points), b) Calculate the depth of total infiltrated water, the depth of surface runoff, and the runoff coefficient (20 points), c) 30-minute unit hydrograph (UH) ordinates are also tabulated above. Obtaining 15-minute UH and neglecting the losses except for the infiltration, determine the direct runoff hydrograph. (30 point).
IQ4// [A]: For a small drainage area, the infiltration rate at the start of rainfall storm was record to be 90 mm/hr and declined exponentially to a constant rate of 8 mm/hr after 2.5 hr. The total infiltration during 2.5 hr was 50 mm. Develop the Horton's equation for the infiltration rate at any time t<2.5 hr. [B]: Find the required discharge of irrigation water at the headwork of the distiriburatry, if the gross area is 20000 mishara, the irrigation intensity is 65%, and the water duty is 1600 hectare/m/sec.
the dmd of the line BC is equal to 426.20. The departure of the line AB is 117.56m. What is then the departure of line BC
A drainage basin has a area of 7322 km2. The average annual precipitation for this area is 909 mm. The average surface water flow at the outlet of the catchment is 21.4 x 108 m3/year and the average groundwater flow out of the basin is 94.6 mm/year. Assume trailing zeros are significant if present. Determine the annual average evaporation in mm/year. (give your answer to one decimal place)

Exercise [1] For a small drainage area, the infiltration rate at the start of rainfall storm was record to be 90 mm/hr and decreased exponentially to a constant rate of 8 mm/hr after 2.5 hr. The total infiltration during 2.5 hr was 50 mm. Develop the Horton's equation for the infiltration rate at any time t < 2.5 hr.
