Elements of the proposed work include synoptic field surveys, remote sensing, numerical modeling, data mining and visualization tools. We plan to: (1) compare base flow behavior from stream gauges in a nested set of watersheds at four different spatial scales from 0.8 to 170 sq km, characterized by diverse patterns of impervious cover and urban infrastructure; (2) conduct a synoptic survey of well water levels to characterize the regional water table; (3) use airborne thermal infrared imagery to identify locations of groundwater seepage into streams across a range of urban development patterns; (4) use seepage transects and tracer tests to quantify the spatial pattern of groundwater fluxes to the drainage network in selected subwatersheds; (5) develop a mass balance for precipitation over a 170 sq km area on a 1 km x 1 km grid using recording rain gages for bias correction of weather radar products; (5) calculate urban evapotranspiration using the Penman-Monteith method compared with results from an eddy correlation station; (7) use numerical groundwater model in a screening mode to estimate depth of groundwater contributing surface water flow; (8) mine data from public agency records of potable water and wastewater flows to estimate leakage rates and flowpaths in relation to streamflow and groundwater fluxes. The CUAHSI HIS tools will be tested in assembling the data sets. |
