Description This project will assess and estimate how much and for how long water can be reasonably stored in Yakima River headwater tributary watersheds, and to evaluate the net gain/loss and timing of floodplain aquifer recharge. The water budget will refine previous estimates by taking into account factors such as the floodplain stratigraphy, geometry of the hydrogeologic units and various parameters of inflow and outflow, including floodplain infiltration, channel discharge, evapotranspiration from floodplain vegetation, and modeling of the seasonal timing of groundwater discharge from the shallow aquifers.
