Blossom Statistical Package for R Blossom Statistical Package for R
Blossom is an R package with functions for making statistical comparisons with distance-function based permutation tests developed by P.W. Mielke, Jr. and colleagues at Colorado State University, and for testing parameters estimated in linear models with permutation procedures developed by B. S. Cade and colleagues at the U.S. Geological Survey' Fort Collins Science Center, U.S...

SEAWAT: A Computer Program for Simulation of Three-Dimensional Variable-Density Ground-Water Flow and Transport SEAWAT: A Computer Program for Simulation of Three-Dimensional Variable-Density Ground-Water Flow and Transport
SEAWAT is a combined version of MODFLOW and MT3DMS for simulation of variable-density groundwater flow and transport.
Surface-Water Routing (SWR) Process: A Program for Modeling Surface-Water Flow with the USGS Modular Groundwater Flow Model (MODFLOW) Surface-Water Routing (SWR) Process: A Program for Modeling Surface-Water Flow with the USGS Modular Groundwater Flow Model (MODFLOW)
The Surface-Water Routing (SWR) Process is used to accurately simulate stages, surface-water flows, and surface-water/groundwater interactions in areas where surface-water gradients are small and/or there is significant management of surface water.
The Pennsylvania Baseline Streamflow Estimator (BaSE) The Pennsylvania Baseline Streamflow Estimator (BaSE)
Estimation of Baseline Daily Mean Streamflows for Ungaged Locations on Pennsylvania Streams, Water Years 1960–2008
Central Valley Hydrologic Model (CVHM) Central Valley Hydrologic Model (CVHM)
The Central Valley Hydrologic Model (CVHM) is an extensive, detailed three-dimensional (3D) computer model of the hydrologic system of the Central Valley (Faunt, 2009). The Central Valley Hydrologic Model (CVHM) simultaneously accounts for changing water supply and demand across the landscape, and simulates surface water and groundwater flow across the entire Central Valley.
