We present in this paper an innovative and sophisticated software environment, called Interactive Groundwater (IGW), for unified deterministic and stochastic groundwater modeling. Based on a set of efficient and robust computational algorithms, IGW allows simulating complex, 3D unsteady flow and solute transport in saturated porous media subject to both systematic and “random” stresses and geol...

Groundwater models are routinely used in hindcasting applications to predict the past concentration levels in contaminated aquifers. These predictions are used in risk assessment and epidemiological studies, which are often completed either for resolving a court case or for developing a public-policy solution. Hindcast groundwater modeling studies utilize a variety of computer tools with comple...

it is over two decades that groundwater flow models are routinely implemented for better management of groundwater resources.modeling groundwater flow with the help of the ground water modeling system (gms) in the damghan plain aquifer in northern iran,which experiences declining levels and numerous environmental hazards, has demonstrated that, (a) in the worst case scenario theaquifer will fac...

This paper reviews groundwater research studies with emphasis on modeling as a tool for management of Hawaii’s resources. Hawaii depends to a great extent on groundwater resources, and concern over availability of potable water has guided research regarding both water quantity and quality. Research is mainly aimed at understanding Hawaii hydrogeology, identifying aquifer parameters and modeling...

The development of accurate mathematical models describing the flow of groundwater is an important problem due to the prevalence of contaminants in or near groundwater supplies. An important parameter of these models is hydraulic conductivity, which describes the ability of the subsurface geology to conduct water flow. Because hydraulic conductivity is a function of the earth's subsurface, dire...

Dimensional Finite Element Model for Pollutant A Two Transport out of Dumped Disposal sites

A truly meshfree method – the radial basis function collocation method is implemented for some 2-D and 3-D groundwater models. The results showed the superior simplicity, general applicability and accuracy of this method, which is a very promising simulation tool in many application areas.

Proper site characterization is vital for cost effective design of a remediation system. Scarcity of data, spatially and temporally varying site conditions and cost associated with sampling, lead to decisions being made under uncertainty which may be categorized as stochastic, lexical or informal. Probability theory, developed for stochastic uncertainties, is not suitable for representing lexic...
