Among all the types of flood, fluvial floods are most common over the entire globe. Hydrodynamic modeling technique is very useful for the development of 1 dimensional and two-dimensional models which can be further utilized for flood mapping. Among various available software, open source software HEC-RAS is most popular and widely used across the globe. This review aims for exploring the various application of HEC-RAS software for development of 1 dimensional hydrodynamic model for various rivers across the world and in the Indian context. The main objective of this review is to study the effectiveness and scope of HEC-RAS software along with GIS techniques to develop hydrodynamic modeling for open channel flow. Various studies across the globe concluded and confirmed the suitability of HEC RAS for development of steady and unsteady hydrodynamic models for an open channel
