O uso de geotecnologias na análise morfométrica da alta bacia hidrográfica do ribeirão Santo Antônio, no município de Iporá-Goiás, Brasil

Resumo

The present paper uses geotechnology for morphometric analysis of high hydrographic basin of Santo Antonio’s river, which is the only source of water for the supply of Iporá city, in the state of Goiás, Brazil. On this study were selected and applied twenty eight morphometric parameters to be analyzed with the purpose of obtaining information of the characteristics of the hidrographic basin. The results of some parameters, such as slope (0-45%), altimetric amplitude (331 m), main channel gradient (11.4 m /km), hydrographic density (1.40 hydrographic channels/km²) and the sinuosity of the main channel (1,424 km/km) showed that the basin is not likely for inundations; however, it has high superficial flowing capacity, because of the rugged terrain. This characteristic of the basin propitiates the superficial flowing of water being unfavorable to the infiltration and hydric reloading of the groundwater table. Therefore, the presented results are relevant to the management and planning of the use of water rate for the public supplying of Iporá city.
