Groundwater-flow model of the Treasure Valley, southwestern Idaho, 1986–2015

Abstract

vii data release provide ample flexibility to improve the model for future uses. Adjustments and improvements could be made by refining the model in an area of interest, collecting additional calibration data, applying more rigorous boundary conditions, or re-estimating model parameters to optimize model performance for a specific model forecast.(3) new flux observations in the form of drain discharges;(4) agricultural pumping, canal seepage, and incidental recharge results from an agricultural and urban water supply and demand model that incorporates new land-use and evapotranspiration (ET) data; and(5) the newly developed hydrogeologic framework from the 3D HFM (Bartolino, 2019a).

Managed aquifer recharge as a strategy to redistribute excess surface flow to baseflow in snowmelt hydrologic regimes

“…There is a large and growing number of publicly available regional groundwater models that can serve as starting-points for model-based site-characterization efforts (ScienceBase, 2023;Zipper et al, 2023). This study leverages a recently published regional groundwater model of the Treasure Valley regional aquifer (Hundt, 2023;Hundt and Bartolino, 2023) located in southwestern Idaho, US (Figure 1A) to explore the baseflow response to a hypothetical transient MAR signal.…”

“…In this work, we demonstrate the use of a 3D regional groundwater flow model (Hundt, 2023;Hundt and Bartolino, 2023) for the Treasure Valley Aquifer in Idaho, US to evaluate hundreds of potential MAR locations for suitability with respect to enhancing seasonal baseflow. This study is meant to show how groundwater modeling and, in this case, a pre-existing model, can aid the identification of promising MAR locations; however, our study is not designed to address regionspecific issues or management goals within the study region.…”
