groundwater recharge from mains leakage CE 394K.3 GIS in Water Resources groundwater recharge from mains leakage Beatriz Garcia-Fresca November 2002

datasets: GEOLOGY

geology + city footprint

datasets: WATER MAINS source: City of Austin GIS datasets

data processing reprojecting  Texas Central State Plane (US ft) spatial analysis  reclassification of geology according to relative permeability calculations: CoA water usage  leakage geoprocessing: isolating pipes by aquifer group

relative permeabilities

datasets: WASTEWATER MAINS Work in progress source: City of Austin GIS datasets

a fun digression

conclusions the urban induced recharge in Austin is significant utility lines can be analyzed using ArcHydro tools ArcGIS presents more operational problems than ArcView

future work add recharge from wastewater mains refine calculations: what are the qualitative implications? refine calculations: include infiltration coeffs. of soils?
