Project Description: Taking advantage of the City of Tucson, Arizona as a living laboratory, this observational study evaluates the cumulative impact of green infrastructure installation in neighborhood streets on stormwater runoff response under varying rainfall regimes and seasonality. This observational study is strongly focused on the development and analysis of high-resolution empirical runoff datasets derived on scales typically underrepresented in data-limited semi-arid urban environments. This study discusses methods and analyses undertaken in order to understand urban hydrologic functioning at the urban subwatershed scale by comparing runoff ratios, runoff volumes, and peak discharge derived for paired events in nested watersheds in two urban neighborhoods in Tucson, Arizona.
