- A small catchment area 300 km2received a rainfall of 15cm in 1 hour, due to a storm draining thecatchment was dry before the storm and experienced a runoff lasting for 5 hours with an averagedischarge Value of 3 m3/sec. The stream was given dry after the runoff event.(a) What is the amount of water in cm3 which was not available to runoff alone to combined effectof infiltration, evaporation and transpiration.(b) What is the ratio of total and direct runoff to precipitation.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 4-hour rain of average intensity I cm/hr. falls over the fern leaf type catchments shown in Fig. below. The time of concentration from the lines AA. BB, CC and DD are 1, 2, 3and 4 hours, respectively, to the site 0 where the discharge measurements áre made. The value of the runoff coefficient C are 0.5, 0.6, and 0.7 for the 1st, 2nd and 3rd hours of rainfall respectively and attains a constant value of 0.8 after 3 hours. Determine the discharge at site O and draw the discharge hydrograph at O?
- please show steps and explain If the rainfall excess consists of two bursts of 3.3 in./hr and 1.8 in./hrs, each for 20 minutes, and the 20-minute UH (1”) hasordinates of 15, 40, 25, and 10 ft3/s, compute the distribution of direct runoff.Assuming that you have gaged rainfall and streamflow data for a given basin: (a) Illustrate and name one baseflow separation method, and explain why the streamflow hydrograph has an initial recession, which defines the beginning of direct runoff. (b) Illustrate and name one infiltration separation method, and explain the assumptions for the application of the method including calibration of the infiltration parameters.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
- A direct-runoff hydrograph due to isolated storm was triangular in shape with a base of 80 h and peak of 200 m^ 3 / s . If the catchment area is 1440 km ^ 2 the effective rainfall of the storm isA lake of surface area 500 Acres received a daily average rainfall equals to (R) mm for a whole month. Direct inflows to this lake during this month were; R, 2R, 1.5R and 3R (in cusecs). Daily evaporation loss during this month was 1R cm/day. Later it was found that the rain gauge was inclined at an angle of 10 degree with the vertical. Direct outflow during this month was 0.25R cusecs/day. Assume the sides of the lake as vertical with initial water depth of 100ft at start of the month. Find the final storage of the lake at the end of the month. Also find the change in storage of the lake and rate of change of storage? Find Your answers in Acre-ft and Acre-ft/month, respectively Note R= 7A small catchment basin with an area of 1.93 square miles received a rainfall of 105 mm in 90 minutes due to a storm. At the outlet of the catchment, the stream draining the basin was dry before the storm and later experience a runoff lasting for 10 hours with an average discharge of 1.45 cms when rainfall occurs. The stream was then again dry after the runoff event. a) determine the amount of water that was not available to runoff due to the combined effect of infiltration, evaporation, and transpiration, b) what is the ratio of runoff to precipitation?
- 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 hrGiven the rainfall excess hyetograph and the 1-hr UH below: Time (hr) 0 1 2 3 4 5 6 7 8 Excess rainfall (in) 1 2 1 0.5 Direct runoff (cfs) 0 100 200 400 300 200 100 50 0 Compute the resulting storm hydrograph and assume no losses to infiltration and evapotranspirationA storm occurred and lasted for 3 hours giving a total rainfall of 45 mm. If initial infiltration rate is 15 mm/h and final infiltration rate is 10 mm/h, find the total infiltration depth if value of ‘k’ is 1. If other losses are negligible, find the effective depth of rainfall.
