HYDROLOGIC AND HYDRAULIC MODELLING INTEGRATED WITH GIS: A STUDY OF THE ACARAÚ RIVER BASIN – CE
Journal of Urban and Environmental Engineering
The paper presents a case study integrating hydrologic models, hydraulic models and a geographic information system (GIS) to delineate flooded areas in the medium-sized Acaraú River Basin in Ceará State, Brazil. The computational tools used were HEC-HMS for hydrologic modelling, HEC-RAS for hydraulic modelling and HEC-GeoRAS for the GIS. The results showed that a substantial portion of the riverine populations of the cities of Sobral, Santana do Acaraú and Groairas were affected by floods.doi:10.4090/juee.2014.v8n2.167174 fatcat:ocb224bvqbhj7mp4lujy2rhnlu
