Cálculo da vazão do córrego Bela Vista, Serranópolis, Goiás: subsídios a pesquisa arqueológica

Abstract

Calculation of the flow rate os the Bela Vista stream was obtained through rudimentary techniques using floats and a ford. The general objective of the research is to determine the average flow in a day, aiming to subsidize the archaeological research in development related to the pre-colonial groups that occupied the GO-Já-02 site, which was identified by the research coordinated by Dr. Pedro Ignacio Schmitz and by Dr. Altair Sales Barbosa between the 1970s and 1980s. The results obtained produced a flow rate of 144 liters per second. Some projections were established based on oral information that indicate variations in the width and depth of the channel and consequently in the flow. It also reveals that the recharge of the Bela Vista stream is carried out from the rainfall and the water table upstream. Consumption projections for hunter-gatherer groups and pottery farmers are hypothetical.
