The present research resulted in hitherto unknown and unexpected results showing that, despite the common belief, surface flow can have a significant and pronounced effect on the establishment and pattern of underground flow. Furthermore the pattern of flow is found to be totally unexpected. Therefore the analysis of underground flow regimes and their role in environmental monitoring and protection and engineering works such as the design of reactive barriers for the remediation of contaminated waters require new approaches. The current work also showed that computer based investigations can generate new avenues for research and totally unexpected results and predictions can be made via their use. Therefore a rigorous and universal predictive model based on a reliable mathematical technique has capabilities well beyond simple correlations constructed using experimental and statistical data.
Study of underground flow of water is of enormous interest in many areas of physical science and engineering. Different patterns of flow resulting from pressure imbalance caused by natural phenomena in underground hydraulic systems are the most significant factors affecting seepage through earth-dams and migration of contaminants under the ground. Therefore predictive analysis of such regimes is of crucial importance in the design of dams, underground reactive barriers, fresh water extraction wells and many other structures which play important roles in modern industrial activities of mankind.
The main focus of the present research has been on the application of numerical modelling to the study of interaction between surface flow caused by rainfall and underground regimes in saturated lands.
