Resumo
Located 149 km away from the state capital of Goiania, the historic city of Goias, GO, was created during the 18th Century “gold rush” to the Vermelho River, which cuts through the city. Ever since, flooding problems have plagued the area. The objectives of this work are to contribute to the understanding and genesis of the flooding spells, and indicate potential control measures. With these objectives in mind, several approaches were utilized, including: an analysis of the geo-environmental aspects of the watershed (climate, geology, geomorphol-ogy, soils, and land/use occupation); a research of how the urban area was developed; a historical research of flooding occurrences; and indication of preventative measures. It has been concluded that the flooding occur-rences result from combined factors characterized by the presence of mountains, enclosed valleys, canyons, steep and rocky slopes, shallow soils, deforestation, and a summer weather pattern known for concentrated heavy rains (or flash floods). Beyond these factors, the use and occupation of the watershed was done haphazardly with no previous planning, and the urban area was built in a totally inappropriate location. Preventative measures are restricted to a two-fold approach of re-ordering the wa-tershed’s land use and building infrastructure projects.
