QUESTION 1 a) A 500 Ha watershed has the landuse/land cover and corresponding runoff coefficient as given below; Runoff coefficient Land use/cover Forest Palm Oil Cultivated land Area (Ha) 250 50 200 0.2 0.3 0.4 ATK The maximum intensity duration frequency relationship of the watershed is given by, i = catchment is located within an area with the IDF constants = 54.265, K = 0.179,0=0.100, and μ = 0.756. Time of concentration is 1-hr. Using Rational Method, estimate the The (d+0)" i 50-yr ARI peak runoff from the watershed. ii 50-yr ARI peak runoff if the forest cover has decreased to 100-Ha with the remaining 150- Ha of forest land is to be converted into palm oil.
