Abstract Sediments produced from eroding cultivated land can cause on‐site and off‐site effects that considerable economic social impacts. Despite the importance of soil conservation practices (SCP) for control erosion improvements in hydrological functions, limited information is available regarding SCP on sediment yield (SY) at catchment scale. This study aimed to investigate long‐term relationships between SY use, management, rainfall a small catchment. To determine anthropogenic climatic...
ABSTRACT The influx of sediments carried by rivers can be measured continuously using a turbidimeter through the indirect relationship between turbidity and suspended sediment concentration (SSC). However, this process is dependent on obtaining water samples with to calibrate turbidimeter. Sampling out different methods, resulting in errors uncertainties estimating SSC. Four possibilities for composition calibration curve were tested order evaluate effectiveness sampling strategies. study...
Abstract To truly understand the hydrologic and erosive processes that occur at catchment scale regarding land use soil management changes, intensive monitoring is required over a long period. Variables such as precipitation, flow rate suspended sediment concentration are fundamentals needed to estimate yield (SY). However, in order shed more light on effects of changes SY, traditional techniques can be paired with tracing identify sources. In addition, mathematical models predict erosion SY...
Abstract Grain crops have expanded at the expense of native grasslands in South America's Pampa biome recent decades, thereby, increasing sediment delivery to river systems. This study aimed evaluate impact land use change on source contributions Ibirapuitã catchment (5942 km 2 ), Southern Brazil. For this purpose, a fingerprinting approach was developed based organic matter composition, ultraviolet–visible reflectance, and fallout radionuclide activities as potential tracers. Four main...
ABSTRACT Agriculture intensification in Southern Brazil’s subtropical regions combined with the frequent occurrence of erosive rainfall has rendered area a global water erosion hotspot. In this scenario, understanding and regulating processes at river catchment scale is critical for mitigating soil resource degradation. Traditional methods tracing sediment sources are expensive time-consuming justify development alternative approaches. Therefore, study, we employed diffuse reflectance...
