Processo: 23081.134873\/2022-81  –   Projeto GAP\/CCR: 058003<\/p>\n

Objeto: Identifying critical erosion hotspots is key for proposing sustainable landscape management to help prepare for the intense use of agricultural areas and the occurrence of intense rainfall events due to climate change. Runoff water connects the eroded sediments and other pollutants from the landscape to water bodies, and accelerated erosion in fragile areas can cause negative effects both on- and off-site. Using the tools of environmental monitoring, we are planning to describe how water flows connect the landscape to the streams, and how sediments and solutes are transported to the river channel in water basins in Southern Brazil. The main objectives of this cooperation project are to describe and quantify the hydrological processes acting on erosion to understand the processes of mobilization and transfer of sediments. The different methodologies used will explore a headwater catchment by monitoring runoff, suspended sediment, nutrient and pesticides concentrations, and estimating the main fine sediment sources to comprehend the impact of its agricultural land use on these transfers. The project will be carried out in a small experimental catchment (Guarda Mor river catchment \u2013 18.5 km2), but also in a large water basin (Uruguay river with 200 000 km2) located in southern Brazil, northern Argentina and western Uruguay based on dating and tracing studies of sediments deposited in the Salto Dam reservoir. The main approaches of this study can be subdivided into the following goals:<\/p>\n

Goal 1: Computational modelling applied to sediment source identification: uncertainty analysis and sample number optimization.<\/p>\n

Goal 2: Improved simulation of runoff and erosion in no-till rural catchments to adapt agricultural production systems to the impacts of climate change.<\/p>\n

Based on these research activities, we intend to generate insightful information and products to improve the land management and soil and water conservation, as well as to train researchers in the areas of environmental monitoring, mathematical simulation, sediment tracing, and the dating of erosion and deposition rates.<\/p>\n
