Estimating Mean Long-term Hydrologic Budget Components for Watersheds and Counties: An Application to the Commonwealth of Virginia, USA

Abstract: Mean long-term hydrologic budget components, such as recharge and base flow, are often difficult to estimate because they can vary substantially in space and time. Mean long-term fluxes were calculated in this study for precipitation, surface runoff, infiltration, total evapotranspiration (ET), riparian ET, recharge, base flow (or groundwater discharge) and net total outflow using long-term estimates of mean ET and precipitation and the assumption that the relative change in storage over that 30-year period is… Show more

“…This technique is associated with greater success when more thematic layers are used to generate the groundwater potential map (Kumar et al 2014). Similar multivariate techniques have been used to assess factors controlling the distribution of groundwater recharge, a controlling factor on water table morphology, in other areas of Virginia (Sanford et al 2015).…”
