Modeling and Simulation in Water Resources Management

One of the most crucial and influential factors in the formation and development of a civilization is the available water resources. The most common and practical way to manage water resources is to model and simulate water systems. In general, modeling is the mapping of a natural phenomenon in the form of physical components or mathematical relationships and involves both physical modeling and mathematical modeling, which are used in mathematical modeling in water resources management issues. Simulation is one of the methods for solving mathematical programming models in situations where the use of algebraic analysis methods is not possible or cannot be tested in the real world. Simulation-based on trial and error examines the effect of different conditions on the system and evaluates the results. With the above-mentioned explanations, through modeling and simulation, in the least time and cost, researcher investigate different options for achieving the goal. This chapter includes details of modeling and simulation in water resources management.
