ABSTRACT
Maintaining the natural distribution of flow within watercourse ecosystems is desirable for the support of downstream fisheries, and preservation of natural channel forming processes. The use of a continuous simulation model offers a significant benefit in terms of allowing evaluation of various water quality and quantity management strategies through a full range of flow conditions including baseflow conditions. The results are provided for the outlet of the developing area which is located downstream of the end-of-pipe facility and includes all drainage from the development area and external drainage which passes through the development area. However their effectiveness is slightly reduced in comparison to source controls or a combination of source controls and an end-of-pipe facility. The HSP-F modeling approach proved to be an effective tool to evaluate various stormwater management practices with respect to their effectiveness in augmenting base flow/interflow linking the hydrologic and hydrogeologic function of the watershed.
