An overview of hydrologic modeling

Abstract

Hydrologic models are developed for the purpose of imitating the actual relationship between the geo-climato-hydrological variables to estimate the future interactions of the same. Hydrologic models are mainly divided into temporal, spatial, and spatiotemporal hydrologic models based on the type of independent variable (time, space, or both). Further, the models can be divided into single or multievent and lumped or distributed. The hydrologic models are also classified with respect to the tools by which the interrelationship of variables are identified. In the present technical note, an overview of hydrologic models is discussed along with thorough descriptions of the different types of models and their applications in various hydrologic problems are also given. © 2010 Springer Science+Business Media B.V.
