If we have a two-hour rain event in the Mt Helen campus of the university with an average intensity of 32 mm/h, use the rational equation to estimate the peak discharge (Qmax) and total volume of runoff (in m?). For that, you have to use the attached campus map and aerial photograph. Assume that the University grounds extend from East Terrace (east), Gear Avenue (south), University Drive (west) and North Terrace (north). Assume this area occupies 0.2 km and that your downloaded map is to scale. Consider three main cover types: Forest (C=0.2), Grass (some trees)/Dirt (C=0.3), Concrete/Roof/Urban (C=0.85). Considering the total rainfall of the two hour period (with constant intensity), what is the percentage of water infiltrated into the terrain? For doing this exercise you have to divide the area of interest (the University Campus in this case) in regular intervals, i.e. an squared mesh of 8x8 (8 squares high for 8 squares wide) and assign a cover type to each sub-square.
