Dear Jamel,

You can use River & Flood Analysis software.

With my best regards

Prof. Bachir ACHOUR

Thank you Professor Bachir

You can perform it on Arcgis also, there is so many hydrological tools are present

Thanks Avinash

You can use CFD Computational Fluid Dynamics

. Various research has

been carried out for flood modelling and simulation of

flood-prone area with the aid of artificial neural network

(ANN) and GIS techniques (Zerger 2002; Islam and Sado

2002; Sanyal and Lu 2004; Knebl et al. 2005; Merwade

et al. 2008; Kia et al. 2011). Rahmati et al. (2015) developed

a flood susceptibility model using frequency ratio and

models of weights of evidence in the Golestan Province,

Iran.

the new version of River & Flood Analysis will be released in late August 2017 and would have been available with the normal version of 2017 Civil 3D.
