Book Urban Stormwater Modeling and Simulation

Download or read book Urban Stormwater Modeling and Simulation written by Stephan J. Nix and published by CRC Press. This book was released on 1994-07-13 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Stormwater Modeling and Simulation discusses several popular stormwater models and explains a variety of uses in practical terms. This unique book is divided into five key sections and begins with a description of urban runoff problems and how computer models play an important role in problem solving. The book continues with detailed discussions on the construction of watershed models, model verification and validation, the use of models for predicting stormwater runoff and pollution discharges, and common problems associated with popular modeling programs. A practical approach is used throughout the book, focusing on actual applications to illustrate basic principles. This is the first book available that provides both new and experienced engineers, consultants, and scientists with an organized approach to stormwater modeling and simulation, model construction, model verification, and software selection. Water quality professionals, environmental engineering students, technical libraries, regulators, and planners will also find this a perfect hands-on learning tool.

Book excerpt: Small storms can have adverse affects on downstream water quality in urbanizing watersheds because impervious surfaces convey greater volumes of runoff and lead to largerstorm flows than under natural conditions (Booth 1990; Beard and Chang 1979). Therefore management of the water quality storm (1.25" of rain over 2 hours) has been targeted in water quality initiatives. This study examined whether reducing the effective impervious area that contributes runoff during the water quality storm by disconnecting it from the stormwater conveyance system could be a viable stormwater management solution in existing residential areas. Disconnection was examined in the Pompeston Creek Watershed, Burlington County, New Jersey on the lot, subdivision, and watershed scale. A calibrated HEC-HMS model of the watershed was used for the watershed scale analysis. The SCS equations to were applied to simulate disconnection by routing runoff from the disconnected impervious surface over an adjacent impervious surface. The 2, 10, and 100-year storms were examined in addition to the water quality storm. Three primary conclusions were made: 1) the composite curve number method, and therefore the composite curve numbers given in TR-55, under-predicts small storm runoff when compared to the volume weighted method because the composite curve number does not account for the runoff conveyed by directly connected impervious surfaces in urbanizing areas; 2) by disconnecting the runoff from the impervious areas by routing it over the pervious area, the runoff volume can be reduced for the water quality storm; 3) the effectiveness of disconnection in mitigating the runoff volumes relies on the infiltration capacity of the pervious area. Both the extent of the under-prediction of the composite curve number and the relative volume reduction achieved by disconnection decrease as storm depth increases. The adjustment of the basin curve number during model calibration for small observed storm events suggested that the original composite curve number method was inadequate in predicting runoff in the watershed scale model for small storms. Basin-wide reductions in runoff volumes with the application of basin-wide disconnection were consistent with the reductions predicted on the smaller scales. These results have a direct application to regional stormwater management planning as disconnection can be a suitable retrofit for the management of the small storm in existing residential areas.

This book was released on 2006 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modified infiltration trenches were simulated for local roads and the TMDL could be met with treatment of 68% of local roads area, which is equivalent to 7% of the upper Ballona Creek watershed area. The construction cost was about $58 million, which is less than one-fourth of the cost needed for the subwatershed approach.
