MODFLOW-NWT model used to demonstrate extending the capture map concept to estimate discrete and risk-based streamflow depletion potential
A previously developed groundwater flow model (https://doi.org/10.5066/P9051RUT)
was slightly modified to estimate the risk-based discrete relation between groundwater
extraction and surface-water/groundwater exchange. Previously, the concept of a
''capture map'' has been put forward as a means to effectively summarize this relation
for decision-making consumption. While capture maps have enjoyed success in the
environmental simulation industry, they are deterministic, ignoring uncertainty in the
underlying model. Furthermore, capture maps are not typically calculated in a manner
that facilitates analysis of varying combinations of extraction locations and/or reaches.
That is, they are typically constructed with focus on a single reach or group of reaches.
The former of these limitations is important for conveying risk to decision makers, while
the latter is important for decision-making support related to surface-water management,
where future foci may include reaches that were not the focus of the original capture
analysis.
Herein, we use a MODFLOW-NWT groundwater/surface-water model of the lower San
Antonio River, Texas, USA to demonstrate a technique to estimate risk-based and
spatially discrete streamflow depletion potential. This USGS data release contains
all of the input and output files for the simulations described in the associated journal
article (https://doi.org/10.1111/gwat.13080)
