The objective of this research project is to better understand the processes that control urban stormwater quantity and quality and to address the potential of low-impact, nonstructural stormwater management strategies using hydrologic modeling.Approach:
To gain a broad-based understanding of urban stormwater infiltration and runoff, field observations will be combined with numerical hydrologic modeling. The first phase of this project will include gathering existing information and developing some simplified preliminary analyses to help clarify the important issues and processes that govern this problem. The second phase will include field infiltration measurements to explore the influence of type of vegetative cover on the infiltration rate, as well as the evolution of infiltration rate over time as vegetation is established. The third phase will approach the problem using computational hydrologic models at a variety of scales. Small-scale modeling will be used to examine local water budgets, infiltration patterns, and runoff and contaminant transport patterns. This will be complemented by large-scale modeling to better understand how the effects of local stormwater management strategies aggregate at the scale of a small watershed.
The research will provide a broad-based understanding of urban stormwater infiltration and runoff and will lead to a better understanding of the processes that control urban stormwater quantity and quality.Supplemental Keywords:
