When assessing climate impact on hydrologic processes, we face a number of different modeling approaches, including forcing dataset, downscaling of atmospheric model outputs, . - BASIC CONCEPTS. Hydrology . Hydrology . is the science of the waters of the . earth and . its atmosphere. It deals with occurrence, circulation, distribution and movements of these waters over the globe and their interaction with the physical and biological environments.
