The combining of the hydro graphs, channel routing, and routing of the flood hydrographs through
the existing ponds were performed using the Storm Water Management Model (SWMM, Reference
2). The resulting hydrology was used to define the water surface profiles for the 10-, 50-, and 100-
year recurrence interval storms by utilizing the United States Army Corps of Engineer's water
surface profile computer program (HEC-2, Reference 15).
