Approaches in highly parameterized inversion - GENIE, a general model-independent TCP/IP run manager Approaches in highly parameterized inversion - GENIE, a general model-independent TCP/IP run manager
GENIE is a model-independent suite of programs that can be used to generally distribute, manage, and execute multiple model runs via the TCP/IP infrastructure. The suite consists of a file distribution interface, a run manage, a run executer, and a routine that can be compiled as part of a program and used to exchange model runs with the run manager. Because communication is via a...

Watershed scale response to climate change--Black Earth Creek Basin, Wisconsin Watershed scale response to climate change--Black Earth Creek Basin, Wisconsin
General Circulation Model simulations of future climate through 2099 project a wide range of possible scenarios. To determine the sensitivity and potential effect of long-term climate change on the freshwater resources of the United States, the U.S. Geological Survey Global Change study, "An integrated watershed scale response to global change in selected basins across the United States"...

Integrated watershed-scale response to climate change for selected basins across the United States Integrated watershed-scale response to climate change for selected basins across the United States
A study by the U.S. Geological Survey (USGS) evaluated the hydrologic response to different projected carbon emission scenarios of the 21st century using a hydrologic simulation model. This study involved five major steps: (1) setup, calibrate and evaluated the Precipitation Runoff Modeling System (PRMS) model in 14 basins across the United States by local USGS personnel; (2) acquire...

MODFLOW-NWT – Robust handling of dry cells using a Newton Formulation of MODFLOW-2005 MODFLOW-NWT – Robust handling of dry cells using a Newton Formulation of MODFLOW-2005
The first versions of the widely used groundwater flow model MODFLOW (McDonald and Harbaugh 1988) had a sure but inflexible way of handling unconfined finite-difference aquifer cells where the water table dropped below the bottom of the cell—these "dry cells" were turned inactive for the remainder of the simulation. Problems with this formulation were easily seen, including the potential...
