2. Discuss the factors affecting the infiltration capacity of an area.
Suppose the parameters for Philip's equation are sorptivity, S = 15 cm/hr!/2 and K= 5cm/hr. A uniform rainfall causes ponding after 20 minutes. Determine the infiltration rate at time t=1 hr. Also compute the cumulative infiltration for the first hour of the rain.
3) The actual infiltration rate is less than the infiltration capacity. * True False
PLS ANSWER ASAP THANKS!
instantaneous infiltration rate can be estimated by the equation, f= 0.5(a / +0.5) + b, where 'a' and 'b' are constants and 't' is the time elapsed from the beginning of the storm. find total infiltration during 10 hours if a=5 mm/hº.5 and b = 10 mm/h.

Infiltration Question 4: Calculate the volume of water (Mm³) evaporated from a catchment of an area of 60 hectares per year if saturation vapor pressure is 80mm of Hg and relative humidity is 70%. The velocity of wind at 25 m above the ground level is 21.5 km/hr. Take K = 0.4.
What do you understand by the term evaporation? If you’re a civil engineering technologist where do you apply this evaporation in your civil engineering related projects explain it? A class-A pan was setup adjacent to a lake. The depth of water in the pan at beginning was 77cm. in that week, a rainfall of 37mm came and 15 mm of water was removed from pan to keep the water level in the specified depth. If the depth of water at end of the week was 186.89 mm, calculate pan evaporation. Using suitable pan coefficient, estimate lake evaporation in that week.

Calculate the clean-bed head loss with Ergun Equation through a deep-bed anthracite filter with 1.8m of ES = 0.95 mm media at a filtration rate of 15 m/h and a temperature of 15 C. (Accept: KV = 228, Kl = 4.4, and ɛ = 0.50. Values of pW = 999 kg/m³ and µ = 1.14 ×103 kg/m • ).
Ex12.3 :the daily groundwater recharge 4mm/day, depth of covered drain 2m,the permissible depth of groundwater 1.2m below soil surface, radius of drain pipe 0.1 m. Find the spacing of drains under the following states: Drain is laid on the impervious layer. The soil is homogeneous with K=1m/day. Drain is 15m above the impervious layer. The soil is non-homogeneous ,the first layer have K=1m/day while the second layer have 0.5 m/day. Drain is 3m above the impervious layer. The soil is homogeneous with K-0.8m/day. Use any available equations (Hooghoudt, Kirkham and Dagan)
