Combining sediment source tracing techniques with traditional monitoring: The “Arvorezinha catchment” experience

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 also help dynamics deposition between hillslope stream channel. Given above, this article provides an overview almost 20 years (2002–2021) Arvorezinha experimental (1.23 km2) located edge Brazilian meridional plateau southern Brazil, which subject extreme due combination factors related agriculture steep slopes. The was selected study site evaluate land-use conservation hydrology SY. text reviews history study, synthesizes main results describes evolution used while giving special attention fingerprinting approach. discusses importance catchment-scale studies for teaching, generating technical-scientific knowledge fostering collaboration national international research groups.
