Groundwater models may be used to predict the effects of hydrological changes (like groundwater pumping or irrigation developments) on the behavior of the aquifer and are often named groundwater simulation models. Groundwater models are used in various water management plans for urban areas. As the computations in mathematical groundwater ...
A hydrologic model is a simplification of a real-world system (e.g., surface water, soil water, wetland, groundwater, estuary) that aids in understanding, predicting, and managing water resources. Both the flow and quality of water are commonly studied using hydrologic models.
is the flood forecasting model, which can be a physically-based model, a data-driven model or a hybrid model depending on the approach chosen. In many operational systems forecasted precipitation is fed into rainfall-runoff and streamflow routing models to forecast flow rates and water levels for periods ranging from a few hours to days ahead ...
The use of GIS to analyze groundwater falls into the field of hydrogeology. Since 98% of available freshwater on Earth is groundwater, [7] the need to effectively model and manage these resources is apparent. As the demand for groundwater continues to increase with the world’s growing population, it is vital that these resources be properly ...
Heavy rain in forecast for the Northeast on New Year's Eve Behind Monday's storm, a second weather system is forecast to drench the East Coast from North Carolina to southern New England on Tuesday.

To estimate the drainage requirement, the use of a hydrogeological water balance and a groundwater model (e.g. SahysMod [8]) may be instrumental. The water balance can be illustrated using a water balance graph which plots levels of precipitation and evapotranspiration often on a monthly scale.
A study published in the Journal of Agricultural and Applied Economics in August 2000 stated that "GMS provides an interface to the groundwater flow model, MODFLOW, and the contaminant transport model, MT3D. MODFLOW is a three-dimensional, cell-centered, finite-difference, saturated-flow model capable of both steady-state and transient analyses.
