We assess spatial temporal variability 65 watersheds MD, metropolitan area during Years Each balance term is quantified independently includes both natural (precipitation, evapotranspiration, streamflow) piped (sewer infiltration inflow [I&I], lawn irrigation, supply pipe leakage) watershed inflows outflows. The analysis also compares Gravity Recovery Climate Experiment storage data with changes calculated using residual between find that when considering only terms, (inflows minus outflows) increases urbanization, largely as a result decrease evapotranspiration modeled land surface model Global Land Data Assimilation System/Noah. During wet years, difference urban rural residuals narrows because increased streamflow. Excess areas exported I&I into wastewater collection pipes; some excess greater than gauged annual outweighs inputs from irrigation leakage analysis. net effect flows export ranging 300 465 mm/yr, underscoring importance interactions engineered infrastructure components.
