Abstract
Problem statement: In three recent decays, computer software's are use d for assessing and predicting of what happened and what will happen for surface and subsurface water. These supplementary tools are calculating and presenting potential recharge of contamination to estimate and assess important issue in hydrogeology such as amount of contamination in drinking water. There is a source of contamination in study area that was approved by some experiments in laboratory. In present study, movement of contamination horizontally and vertically simulated. Approach: Visual MODFLOW used to determine movement of groundwater and fate of contamination (phosphorus) by two different types of computers. Results: The results showed that both computers were able t o run the software without critical problem. Also it was found that vertical migration is mainly responsible to migration of contamination. Conclusion: In conclusion, the software performance can be sk ilful and accomplished. It is able to solve a wide range of research problems with low rate of the errors.
Highlights
Computer modelling and simulation are applying these softwares are Groundwater Modelling System (GMS), Groundwater Vistas, Visual MODFLOW, MODFLOW SURFACT, POLLUTION and they are to predict water movement and contamination using all over the world by different environmentalists, migration in surface water and groundwater regime, and hydrologists and hydrogeologists
MODFLOW (three-dimensional block-centred based on certain simplifying assumption (Kumar, finite-difference groundwater flow model), a computer program, has been developed by McDonald and Groundwater simulation by computer is a Harbaugh (1988) in the form of modular threespecialized field that requires considerable training and Dimensional groundwater flow model for US experience
The results were obtained by using Visual MODFLOW Version 4.2 for predicting migration of contamination in pond, swamp and groundwater and interaction between them in the study area for 50 years
Summary
Computer modelling and simulation are applying these softwares are Groundwater Modelling System (GMS), Groundwater Vistas, Visual MODFLOW, MODFLOW SURFACT, POLLUTION and they are to predict water movement and contamination using all over the world by different environmentalists, migration in surface water and groundwater regime, and hydrologists and hydrogeologists Most of has been known to scientists for long time since software package, such as Groundwater Vistas, Visual assessment and monitoring of the underground Argus ONE, Groundwater Modelling System (GMS) reservoirs are too difficult exercises These methods are and recently MODFLOW-CFP using MODFLOW for reliable to determine the groundwater flow and modeling. MT3DMS is a three dimensional multispecies contaminant transport model for simulating of solute transport processes (Zheng, 2009) It is based on the advection-dispersion formulation for modelling of saturated and unsaturated zone and interaction between surface water and subsurface water. There has been a wide development in MT3DMS since the first released in 1990 which was known as MT3D It supports simulation of different species mass transport. The results were obtained by using Visual MODFLOW Version 4.2 for predicting migration of contamination in pond, swamp and groundwater and interaction between them in the study area for 50 years
