The interception of rainwater in annual and perennial agriculture has been the object of several studies in the last decades. However, scant attention has been paid to where this research has taken place and which principal crops have been studied. T

Changes in land use interfere with river basin connectivity, affecting the flow dynamics, sediment yield, and density of river connections with roads. In this research we studied the variation of land use from 1980-2002-2016 using vector mappings in

Surface hydrological processes are essential to the understanding and prediction of soil erosion. Several equipments are used to measure infiltration rate, runoff and soil loss. However, researchers build their own equipment due to the specific sites

The presence of compacted layers in soils can induce subprocesses (e.g., discontinuity of water flow) and induces soil erosion and rill development. This study assesses how rill erosion in Oxisols is affected by a plow pan. The study shows that chang

O traçado das estradas que cortam grande número de rios e a drenagem lateral nas estradas faz com que as águas cheguem rapidamente à rede de drenagem aumentando a vazão. Disso resulta grande produção de sedimentos haja vista que algumas estrad

Gully erosion occurs by the combined action of splash, sheetwash and rill-wash (interrill and rill erosion). These erosion processes have a great capacity for both sediment production and sediment transport. The objectives of this experiment were to

O papel do fogo nos processos ambientais é amplamente reportado nos diversos ecossistemas da Terra. O fogo influencia diversos processos ambientais no solo (e.g. infiltração, erodibilidade, dinâmica de matéria orgânica etc.). Os objetivos deste
