The development of GMS was funded primarily by The United States Army Corps of Engineers and was known until version 4.0, released in late 1999, [3] as the Department of Defense Groundwater Modeling System, or DoD GMS.
This allows differences of opinion about how system processes function to be tested. Such testing is an important part of multi-modeling, or alternative hypothesis testing. Models like MODFLOW make this kind of testing more definitive and controlled. This results because other aspects of the program remain the same.
The database approach is also used for field data; as a result, the GEMSS viewers can be used to display model results, field data or both, a capability useful for understanding the behavior of the prototype as well as for calibrating the model. The field data analysis features can be used independently using GEMSS modeling capability.
"The obtained numerical models were developed using the program Surface-water Modeling System (SMS) v.10.1.11, which was designed by experts from Aquaveo company. The hydrodynamics of the studied sector, obtained using the SMS module named RMA2 [13], served as input for the RMA module 4, which determined the pollutant dispersion" (Marusic and ...
The GSSHA model [3] [4] [5] was derived from the CASC2D hydrologic model. [ 6 ] [ 7 ] GSSHA represents a significant improvement on CASC2D in terms of capabilities, options, and numerical procedures. GSSHA includes dynamic time-stepping depending on stability criteria, different time steps for different numerical processes, and the ability to ...
Yet, like the truly 3-dimensional models, such models do permit the introduction of horizontal and vertical subsurface drainage systems. Semiconfined aquifers with a slowly permeable layer overlying the aquifer (the aquitard ) can be included in the model by simulating vertical flow through it under influence of an overpressure in the aquifer ...

Geomodelling is related to the concept of Shared Earth Model; [2] which is a multidisciplinary, interoperable and updatable knowledge base about the subsurface. Geomodelling is commonly used for managing natural resources , identifying natural hazards , and quantifying geological processes , with main applications to oil and gas fields ...
