Methodologies of Scenario Development for Water Resource Management

Abstract

Efficient management of the resources requires applying scenario development, which helps manage future needs and available resources with lesser difficulties. In this chapter, one of the most vital sources for life, water resources, has been reviewed for the various methodologies and modelling approaches adopted in its scenario development. Scenarios have been planned considering different possibilities incorporating various water balance models, climate models, prediction, and simulation methods. All the methods encountered are either predictive or derivative for the predicted values. Predictions are carried out either by hybridizing the methods or in isolation, but ultimately require derivative models to generate the results. Encountered methods are found complex having rigorous prediction processes. Further directions are suggested (1) to make more straightforward and more uncomplicated prediction methods with the principle to make science for all; and (2) empowering Geographic Information System for predicting future besides presentation and analysis
