Analyzed frequencies of hydrological and meteorological data; and prepared rainfall IDF curves. Estimated runoffs in rivers and determined design high water levels in rivers, designed culverts, side drain and cross drain structures and simulated bridges flow and analyzed the general and local scouring depths under bridges. HEC-RAS was employed for river and bridge flow modeling and for bridge scour analysis. Flood inundation modelling was done by MIKE FLOOD, identified the flood risk areas, prepared flood maps and proposed mitigation measures.
