MODFLOW and Related Programs
MODFLOW is the USGS's modular hydrologic model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions. MODFLOW 6 is presently the core MODFLOW version distributed by the USGS.
Potential for Increased Inundation in Flood-Prone Regions of Southeast Florida in Response to Climate and Sea-Level Changes in Broward County, Florida, 2060–69
The U.S. Geological Survey, in cooperation with Broward County Environmental Planning and Resilience Division, has developed county-scale and local-scale groundwater/surface-water models to study the potential for increased inundation and flooding in eastern Broward County that are due to changes in future climate and sea-level rise. The purpose is to provide information that can be used to help...
Effects of hydrologic system alterations on salinity in the Biscayne aquifer in Broward Co.
To address concerns about the effects of water-resource management practices and rising sea level on saltwater intrusion, the U.S. Geological Survey in cooperation with the Broward County Environmental Planning and Community Resilience Division, initiated a study to examine causes of saltwater intrusion and predict the effects of future alterations to the hydrologic system on salinity distribution...
Simulating Land Subsidence
The California Water Science Center has been involved in multiple studies simulating land subsidence associated with groundwater withdrawal. The simulations can be used to estimate the magnitude, location, and timing of subsidence. They can also be used to evaluate management strategies to mitigate adverse effects from subsidence while also optimizing water availability.
Groundwater Models
Groundwater is an important resource, but availability, quality, and sustainability during growth have become major concerns. Groundwater models are numerical representations that help hydrologists better understand groundwater systems. These models also provide tools for water managers. The Utah Water Science Center has groundwater models for many seperate areas in Utah as well as two regional...
Houston Area Groundwater Level and Subsidence Monitoring
In cooperation with Harris-Galveston Subsidence District, the City of Houston, Fort Bend County Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District, the USGS Oklahoma-Texas Water Science Center Gulf Coast Program collects, processes, and interprets groundwater-level and aquifer-sediment-compaction data to understand the effects of...
MODFLOW models for the simulation of groundwater-flow dynamics in the U.S. Northern High Plains driven by multi-model estimates of surficial aquifer recharge. MODFLOW models for the simulation of groundwater-flow dynamics in the U.S. Northern High Plains driven by multi-model estimates of surficial aquifer recharge.
There is a growing interest in incorporating higher-resolution groundwater modeling within the framework of large-scale land surface models (LSMs), including new processes such as three- dimensional flow, variable soil saturation, and surface water/groundwater interactions. Conversely, complex groundwater models (e.g., the U.S. Geological Survey Groundwater-Flow Model, MODFLOW) often use...

The U.S. Geological Survey (USGS), in cooperation with the Harris-Galveston Subsidence District and Fort Bend Subsidence District, constructed a finite-difference numerical groundwater-flow model of the northern Gulf Coast aquifer region for 1897 through 2018 using MODFLOW 6 with the Newton formulation solver to simulate groundwater flow and land-surface subsidence. Model parameter...
MODFLOW 6 model of two hypothetical stream-aquifer systems to demonstrate the utility of the new Mover Package available only with MODFLOW 6 MODFLOW 6 model of two hypothetical stream-aquifer systems to demonstrate the utility of the new Mover Package available only with MODFLOW 6
Two MODFLOW 6 (version 6.2.1) models of hypothetical stream-aquifer systems are presented for the demonstration and utility of the Water Mover (MVR) Package available only with MODFLOW 6. Using a generalized approach, MVR facilitates the transfer of water among many arbitrary combinations of simulated features (i.e., pumping wells, stream, drains, lakes, etc.) within a MODFLOW 6...
National-Scale Grid to Support Regional Groundwater Availability Studies and a National Hydrogeologic Framework National-Scale Grid to Support Regional Groundwater Availability Studies and a National Hydrogeologic Framework
The National Hydrogeologic Grid (NHG) dataset includes a raster and vector representation of 1-km cells defining a uniform grid that encompasses the continental United States. The value of each cell of the raster dataset corresponds to the 1-km cell number defined as 'cellnum' in the attributes of the vector data. The NHG consists of 4,000 rows and 4,980 columns, numbered from the top...

A new groundwater energy transport model for the MODFLOW hydrologic simulator A new groundwater energy transport model for the MODFLOW hydrologic simulator
Heat transport in the subsurface is an important aspect of research related to the effects of a warming climate on ecological services (i.e., cold-water refugia); the development of geothermal resources for energy banking schemes (i.e., aquifer thermal energy storage [ATES]); and the effects of temperature on other aspects of groundwater quality, such as nutrient cycling. Historically...
