Utilizing the software program HEC- HMS, the hydrologic team conducted a simulation to determine the hydraulic peak flow caused by Shabakunk Creek. Within the simulation, a watershed area was created, and the model was run by inputting National Weather Service rainfall data from a 100-year storm event (Figure 1). The peak flow was calculated to be 1386.8 cubic feet per second. These outputs are exemplified in Figure 2. The next step for the hydrologic team will be to calculate the peak flow caused by the placement of the dormitory building. Once that value is determined, the storm water basins can be designed for the project. Figure 1: HMS Model of Watershed Area and Sub-basin Figure 2: Table of Results from HMS Program. It shows Peak Flow for a 100 Year Storm Event.
