Edmands Brook flows through BC's Newton campus and has a small, partially urbanized drainage basin (Figure 1, below). The total drainage area (A) of the Edmands Brook watershed (EBW) is 0.787 km2. The urbanized portion, or area of impervious surface (Aimp), of the EBW is 0.258 km2. On March 30, 2001 a small rainstorm hit Massachusetts. The March 30 event data collected at Logan Airport shows that the peak rainfall intensity (I) was 0.30 in/hr. You can assume that the rainfall intensity at Logan also applies to the Edmands Brook watershed. Using the values given in the preceding paragraph and the rational runoff equation (Q = CIA), determine the peak discharge of Edmands Brook during this storm. Note for the rational runoff equation: Q is water flow (in m3/s); C is the fraction of the watershed that is impervious, or the percentage of the rainfall to the watershed that is running off directly into the stream during the storm (value between 0 and 1); I is rainfall intensity (in m/s); A is watershed area (in m2). You will need to do a few conversions to get the units right (2.54 cm = 1 in; 1 cm = 0.01 m; 1
