ABSTRACT
The hydrologic and water resources problems in South Asia are discussed in Chapter 1. It is anticipated that the problems will be exacerbated if basin-wide temperature and precipitation would change due to climate change. Quantification of possible changes in river discharge (mean or peak) is achieved with the application of hydrologic models. Four types of hydrologic model - empirical, water-balance, conceptual lumped-parameter and process-based distributed models - are used for hydrologic modeling.
