The simplest systems modeling water treatment water molecules as rigid and depend only on non-bonded interactions. Climate change and the pressure change on our human environment call for us to have foresight about the future sustainability of water resources and thus requiring the use of water modeling.

Groundwater models are used by hydrogeologists and can be defined as systems computer models of groundwater flow. Groundwater models are used to simulate and predict the conditions of the aquifer. Research on groundwater modeling focuses on the development and application of groundwater models to improve the understanding of hydrological processes and groundwater. Research on groundwater modeling also allows predictions to future.

Simulation research of groundwater is conducted in collaboration with research institutes and other universities, industry, regulatory environment, governmental and non-governmental organizations that meet a wide range of environmental issues, including:

- The effects of climate change on groundwater resources
- Impact of CO2 injection and underground storage of water resources
- Changes in groundwater flooding and drought occurrence
- Effect of pollution on agricultural water quality
- Quantification of national water resources
- Impacts of groundwater abstraction on rivers
- Development of new groundwater supply public
- Effectiveness of programs to fight against floods
- Effectiveness of geothermal heating and cooling systems
- Movement of contaminants in groundwater

In addition to several research activities, pollsters undertake projects geological modeling of water for several commercial clients. Modellers groundwater must be qualified in two existing modeling tools applicable as well as the development of custom software to make healthy responses to customer inquiries.

Geological survey institutes to develop different types of modeling tools software to simulate groundwater aquifer systems at different scales. To address various issues related to changes in the environment, today's research is increasingly interdisciplinary. This involves the integration of models from different compartments of the water cycle. To do this, various software tools are implemented to allow different models to interact with each other. New technologies are used to connect different types distinct from those of other software developers environment. This has been used in the past to simulate the processes that took place in Oxford on groundwater flooding river centered in July 2007.

Various other studies using groundwater models are used to predict the effects of various hydrological changes such as irrigation projects on the behavior of the aquifer or groundwater abstraction and are often referred to simulation models groundwater. Nowadays, various groundwater models are also used in the different planes of water management in urban areas.

Applying a model of groundwater to a real situation depends on the accuracy of the input data and the parameters. As parameters are quite variable in space, expert judgment is required to arrive at representative values. Groundwater models are known to be found in different dimensions - dimensional, two-dimensional and three-dimensional and three-dimensional semi-also.

A simulation of the water increased computational cost with the number of interaction sites in a model of water. When hard water modeling systems are used in molecular dynamics, a crop additional costs on the rise - keeping the structure constraint using algorithms of constraints.
