Modeling aspects have added a new dimension in research innovations in all branches of engineering. In the field of soil and
water engineering, they are increasingly used for planning, development, and management of land and water resources, including
analysis of quantity and quality parameters of surface and ground water, flood forecasting and control measures, optimum allocation
and utilization of irrigation water. The application of these models saves considerable time in decision support systems and
helps in conservation and optimum allocations of scarce precious natural resources.
