Model Information
For more information about this model, go to water.usgs.gov
Spatial Resolution
A regional area of analysis is designed in the saltwater intrusion model. Centered-block finite difference allows for variable grid sizes to be specified.
Temporal Resolution
The temporal resolution is user specified. Time step is on the order of seconds. Improperly specified time steps can cause model instability.
Outputs
Model outputs include predicted salt and fresh water levels within an aquifer and around withdraw points.
