Resumo
Large government projects in the Brazilian Amazon, particularly the opening of highways, have always caused a strong impact and several territorial transformations marked by aspects related to the abundance of rivers and their considerable flows, as well as the lack of maintenance of drains arranged along these roads. The objective of this article is to demonstrate aspects related to surface runoff on the Rodovia Expresso Porto, in the municipality of Porto Velho, State of Rondônia, Brazil, with emphasis on the three main hydrographic channels that cross the highway. The research presents a qualitative-quantitative approach using the hypothetical-deductive method, seeking to characterize the study area with bibliographical research and the use of remote sensing techniques in the preparation of thematic maps. The results point to problems in two of the three culverts analyzed, not due to insufficient diameter for flow, but rather due to the considerable difference in level at which they were placed, as well as the lack of maintenance to remove soil and other waste at their entrance. In this context, the importance of good topographic studies to support future similar engineering works is evident.
