RAINFALL RUNOFF MODELLING USING HEC-HMS & GIS TECHNIQUES - A REVIEW

Amit Yadav, H. L. Tiwari, Ankit Balvanshi

Abstract :

Hydrologic models are simplified, conceptual representations of a part of the hydrologic cycle. The Hydrological Cycle is the journey water takes as it circulates from the land to the sky and back again. The water cycle is never –ending cycle. Rainfall–runoff modeling in the oader sense a hydrological, mathematical model gives a detailed account of Rainfall–Runoff relationships of a catchment area or watershed. Hydrological models are primarily used for hydrologic prediction and for understanding hydrologic processes. Watershed hydrological modeling and associated caliation and validation processes require a large set of spatial and temporal data. In practice, the availability and quality of these data are often an issue to cope with. The current paper describes the study of various literatures on development such a strategy by combining fine–scale event and course scale continuous hydrological modeling with hydrologic engineering center’s hydrologic modeling system (HEC–HMS.
