Models for Water Quality Control by Stormwater Ponds

Abstract

The design of stormwater management quality control ponds is largely based on empirical practices which have been developed over time by water resources engineers. The chapter discusses the analytical model results are compared to those of continuous simulation models for the quality control performance of stormwater management ponds, namely extended detention dry and wet ponds. As a result, stormwater ponds have also been used to enhance the quality of runoff entering receiving waters. The primary objective of this work is to model the performance of stormwater quality control ponds, including both extended detention dry and wet ponds, with varying detention times using continuous simulation models as well as analytical probabilistic models. An illustration of this application is also given herein where the analytical models are used to estimate the performance of extended detention wet ponds for varying ratios of active storage volume to pennanent pool storage volume.
