Can you help me solve this homework problem

|Q4|// |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.

Determine the required area (in ft ) of a bioretention basin to service runoff from a shopping complex with 4   .2 acres of paved parking,   1.1 acre of sidewalks,   0.5 acre of landscaping.   The 24-hr design storm is 1 inch. Use the empirical coefficients in Small Storm Hydrology method. There is no underdrain pipe for the bioretention basin. Use the following guidelines for the design:   Ponding depth = 12 inch   Media bed: 36 inches deep, porosity = 0.30   Gravel bed: 24 inches deep, porosity = 0.36

This is a cross-section of a groundwater situation. Label the location of the: Zone of Saturation, Zone of Aeration, Water Table, and Perched Water Table. Examine the diagram and tell me if the Winiecke River will gain water from the groundwater system or will it contribute water to the groundwater system.

Along a day, precipitation is monitored four times with equal time intervals. The recorded data were 10, 12, 16, 8 mm for a catchment has an area of 3000m2. If the measured runoff in this day was 90m3, the infiltration rate is equal to

3. A 5-acre apartment complex receives 1.25 in./hr. of rain for 6 hours. During the storm event, 0.1 in/hr. of water evaporates, and a volume of 15 acre-inches accumulates on the lot. The rest leaves the lot as runoff. Assume that there is no infiltration in this scenario. a. Using a water balance, determine the total volume of runoff generated by the storm. b. Calculate the runoff coefficient.

If the ratio between the length of the tape to its width is 45, the number of tapes used to irrigate a field 300 tapes, the irrigation time per tape is 55 minutes, and the available irrigation current is 30 L / sec, calculate the length of the tape and the design flow rate in units of M '/ hr if you know that the irrigation efficiency is% 70, the effective root zone depth is 1.5 m, the moisture depletion rate is 60%, and the water holding capacity is 1.3 mm / cm.

Be quick sir. Please.
