Flood Analysis Using Integrated HEC-RAS and GIS: A Case Study of Nashik city, India
Abstract: The developmental activities in the urban areas are severely affecting the river flow pattern of the rivers; especially the rivers which pass through the urban habitation are causing heavy floods. The effect of encroachment in the city limits due to urbanization reduces the flow path of rivers causing flooding in adjacent areas. The available data indicates that causalities due to increased frequency of occurrence of flood have increased from 1000 …
