| Abstract: | Urbanized watersheds produce instantaneous response to rainfall resulting in storm water runoff
exceeding the carrying capacity of drainage systems, management of which is important to
prevent flooding and erosion of streams. Management can be achieved using structural storm
water Best Management Practices (BMPs). The city of Austin envisioned a plan to mitigate
future scenarios on flooding and erosion, resulting in the development and integration of storm
water BMP algorithms into the sub-hourly version of Soil and Water Assessment Tool (SWAT)
model. Algorithms were developed to simulate the physical processes governing the flow
transport mechanisms through these BMPs. They were tested using a previously flow-calibrated
watershed in the Austin (Texas, USA) area. Retention irrigation system is one such BMP
commonly found in Austin. This short communication describes the development of a modeling
tool for RI system and its potential applications. From the test results obtained, it appears that the
RI algorithm is functioning rationally. The algorithm developed could be used to evaluate the
functionality of individual BMP structure, to analyze the benefits of such structures at watershed
scale and as design tool. |
