MODFLOW-NWT and MODPATH groundwater flow models of the Farmington River Watershed (Connecticut and Massachusetts)
Groundwater flow models have the potential to predict spatial groundwater discharge
dynamics within river networks, but models are often not evaluated against discharge
dynamics. The objective of this study was to understand the variation in simulated
discharge dynamics (discharge location, flowpath depth, and subsurface travel time)
for models with common, but varying frameworks and assumptions. The University of
Connecticut in collaboration with the United States Geological Survey developed a
groundwater flow model (MODFLOW-NWT) for the Farmington River Watershed
(1,570 km2) in the northeastern United States and systematically varied the type
of typical calibration data (well head and stream elevation); calibration parameters;
parameters related to permeability of the surficial materials, bedrock, and riverbed
sediments; control of river-aquifer exchange directionality; and model resolution.
Each model variation has an associated particle tracking (MODPATH) model.
Subsequent work, not described in this model archive, compared with simulated
spatial patterns of groundwater discharge with patterns observed with hand-held
thermal infrared imagery. This dataset contains model inputs and outputs,
post-processing python scripts, and pest calibration input files for 12 model
variations described in the associated journal article
