RESTORE/fdclmrpplo, Source code for estimation of L-moments and percent no-flow conditions for decadal flow-duration curves and estimation at level-12 hydrologic unit codes along with other statistical computations RESTORE/fdclmrpplo, Source code for estimation of L-moments and percent no-flow conditions for decadal flow-duration curves and estimation at level-12 hydrologic unit codes along with other statistical computations
The RESTORE/fdclmrpplo repository contains R language source code used for estimation of the L-moments and percent no-flow conditions (no-flow fractions) for decadal flow-duration curves and estimation at streamgages and level-12 hydrologic unit codes using generalized additive models and censored generalized additive models. The source code is designed to streamline the workflow for the...
PRMS version 5.0.0: Precipitation-Runoff Modeling System PRMS version 5.0.0: Precipitation-Runoff Modeling System
The need to assess the effects of variability in climate, biota, geology, and human activities on water availability and flow requires computer models that simulate the hydrologic cycle at a watershed scale. The Precipitation-Runoff Modeling System (PRMS) is a deterministic, distributed-parameter; physical process based modeling system developed to evaluate the response of various...
GSFLOW: Coupled Groundwater and Surface-Water Flow Model, version 2.1.0 GSFLOW: Coupled Groundwater and Surface-Water Flow Model, version 2.1.0
GSFLOW is a coupled Groundwater and Surface-water FLOW model based on the integration of the USGS Precipitation-Runoff Modeling System (PRMS-V) and the USGS Modular Groundwater Flow Model (MODFLOW-2005 and MODFLOW-NWT). GSFLOW was developed to simulate coupled groundwater/surface-water flow in one or more watersheds by simultaneously simulating flow across the land surface, within...
VS2DRTI - A Graphical Software Package for Simulating Water Flow, Heat Transport, and Reactive Solute Transport VS2DRTI - A Graphical Software Package for Simulating Water Flow, Heat Transport, and Reactive Solute Transport
VS2DRTI is a graphical software package for simulating water flow, heat transport, and reactive solute transport in variably saturated porous media.
utc2nwislocal, UTC date-times to NWIS local time zones using UTC offsets utc2nwislocal, UTC date-times to NWIS local time zones using UTC offsets
The utc2nwislocal package in the R language provides a light-weight, dependency-free utility for converting Coordinated Universal Time (UTC) base::as.POSIXct() date-time values into character-string representations for time zones. The UTC offsets for individual time zones are determined from the time-zone codes recognized by the U.S. Geological Survey National Water Information System...
