Abstract:
In this example, an analysis of runoff hydrograph generation, a determination of infiltration loses for a single pond, and routing of the runoff hydrograph through the retention pond for peak stage and discharge determination, as well as generation of a routed hydrograph are demonstrated. With the MODRET 6.1 we will generate a single watershed runoff hydrograph hydrographs. Wet ponds are constructed basins that have a permanent pool of water throughout the wet season, potentially extending throughout the year. The primary removal mechanism is settling while stormwater runoff resides in the pool. Where algae are present, algal uptake also aids stormwater treatment. Nutrient uptake also occurs through biological activity in the sediment and water. Wet ponds differ from constructed wetlands in that they are typically deeper, ranging from 4 to 6 feet, and have less vegetative cover. Wet ponds are among the most cost-effective and widely used stormwater treatment practices.
