MODFLOW-NWT groundwater flow models and MODPATH6 particle tracking simulations were developed to determine contributing areas (CAs) for and advective travel times to domestic wells under extreme...
-
Stream restoration goals include reducing erosion and increasing hyporheic exchange to promote biogeochemical processing and improve water quality. Suspended fine particles (<100 µm) exchange...

This model archive documents a transient groundwater-flow model that simulates hydrologic conditions in the Long Island aquifer system for the year 2010, using the U.S. Geological Survey...
-
MODPATH simulations were performed using the MODFLOW groundwater flow model by Wright and others (2023) as the basis, with particles originating from five separate areas in or near Joint Base...
-
Measurements of changes in the distance (or length) between monuments are provided. These measurements were made using a two-color Electronic Distance Meter (EDM) that can measure distances...

A three-dimensional groundwater flow model (MODFLOW-NWT) of the Columbia Plateau Regional aquifer (CPRAS) in Washington, Oregon, and Idaho was developed to provide an integrated understanding of...
-
Six hypothetical 1-dimensional models are used to verify and demonstrate new unsaturated-zone heat transport functionality added to MT3D-USGS (version 1.1.0). Because the governing equations...
