1. PULSE: Model-Estimated Ground-Water Recharge and Hydrograph of Ground-Water Discharge to a Stream [USGS_PULSE]
The computer model PULSE can be used to construct a hydrograph of groundwater discharge to a stream. The model is applicable to a groundwater flow system that is driven by areally uniform recharge ...

2. Precipitation-Runoff Modeling System [USGS_PRMS]
The Precipitation-Runoff Modeling System is a deterministic, distributed-parameter, physical process based modeling system developed to evaluate the response of various combinations of climate and ...

3. RORA: The recession-curve-displacement method for estimating recharge [USGS_RORA]
The computer program RORA estimates groundwater recharge using the recession-curve-displacement method. The method is based on the change in total potential groundwater discharge that is caused by ...

4. Wave Model [USGS_WAVE_MODEL]
A model was constructed within ArcGIS 9.2 to create several useful wave outputs. Significant wave height, wave length, spectral peak wave period, shear stress, and maximum orbital wave velocity can ...

5. Wind Fetch Model [USGS_WIND_FETCH]
Models based upon coastal engineering equations have been developed to quantify wind fetch length and several physical wave characteristics including significant height, length, peak period, maximum ...

6. MOD-PREDICT: Software For Ground Water Analysis [USGS_MODPREDICT]
The MOD-PREDICT program makes definition and analysis of predictions easier for users of MODFLOW-2000 and enhances the analysis capabilities of model fit to observations and prior information.

7. PHAST: A Computer Program for Simulating Ground-Water Flow, Solute Transport, and Multicomponent Geochemical Reactions [USGS_PHAST]
The computer program PHAST ( PH REEQC A nd H ST 3D) simulates multicomponent, reactive solute transport in three-dimensional saturated groundwater flow systems. PHAST is a versatile groundwater flow ...

8. Streamflow routing in upland channels or channel networks [USGS_DAFLOW]
The DAFLOW model routes flows through a system of inter-connected one-dimensional channels and subdivides the system into a series of branches, with each branch divided into a number of subreaches. ...

9. Branch-Network Dynamic Flow Model [USGS_BRANCH]
The Branch-Network Dynamic Flow Model--BRANCH--is used to simulate steady or unsteady flow in a single open-channel reach (branch) or throughout a system of branches (network) ...

10. SPAtially Referenced Regressions On Watershed Attributes (SPARROW) Modeling of Surface-Water Quality [01-usgs_sparrow-01]
The SPARROW method uses spatially referenced regressions of contaminant transport on watershed attributes to support regional water-quality assessment goals, including descriptions of spatial and ...

11. MODFLOW - the Modular Three-Dimensional Finite-Difference Ground-Water Flow Model [modflow-99]   CHILD DIFs
The modular finite-difference ground-water flow model (MODFLOW) is the USGS's modular hydrologic model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions ...

12. NASA-CASA Biosphere Model - Interannual simulations for the 1980's [NASA_CASA_BiosphereModel]
The NASA-CASA (Carnegie-Ames-Stanford Approach) model simulates net primary production (NPP) and soil heterotrophic respiration (Rh) at regional to global scales. Calculation of monthly terrestrial ...

13. The Hydrological Routing Algorithm (HYDRA) [NASA_CASA_HYDRA]
The Hydrological Routing Algorithm (HYDRA) is a computer model that simulates the regional scale flow of water (Coe et al., 2000). HYDRA simulates a set of physical hydrologic processes including ...

14. VSIM - Water Balance Model [VSIM]
VSIM is a simple water balance model embedded in an Excel spreadsheet that simulates the daily and seasonal water balance for a vineyard (block) given data on weather, soils, and leaf area. VSIM takes ...

15. Dynamic Global Vegetation Model (DGVM) [NASA_CASA_DGVM]
A Dynamic Global Vegetation Model (DGVM) has been developed as a new feature of the NASA-CASA (Carnegie Ames Stanford Approach) ecosystem production and trace gas model (Potter and Klooster. 1997). ...

16. EGM96 - The NASA GSFC and NIMA Joint Geopotential Model [EGM96_NASA-NIMA]
EGM96 is a geopotential model of the Earth consisting of spherical harmonic coefficients complete to degree and order 360. It is a composite solution, consisting of: (1) a combination solution to ...
