Evaluation of water erosion on rural roads: A case study in the rural community of the Placa, Alegre/ES, Brazil

Abstract

This study aimed to estimate the loss of soil by water erosion that occurs in a stretch of rural road Alegre municipality, ES, Brazil. The estimate was based on the accumulated volume of earth per four structures such as " retention basins " of semicircular shape, arranged in series ( 7 of 7 m) and installed on the roadside. The results indicate that rural road has advanced erosion process. The land volumes of 0,0310 m³, 0,0122 m³, 0,0068 m³ and 0,0065 m³, retained on structures after six months of observation, reinforce the need for conservation practices on site.
