AIH Webinar: Surface Hydrology Research in Agricultural Watersheds in South Brazil

March 21 @ 12:00 pm - 1:00 pm PDT

Join AIH for this month’s webinar presented by Alice Dambroz, a PhD student in Soil Science at Universidade Federal de Santa Maria, in Brazil.

AIH Members = Free
Non-members = $35

Webinar Summary: For over twenty years, agricultural watersheds have been hydrologically monitored in South Brazil. These monitoring projects seek to quantify and understand the impact of agricultural activities on processes related to surface hydrology and soil erosion. These watersheds represent different scales, geomorphological characteristics, and land uses. They are also used as experimental watersheds for the purposes of teaching and training students and future researchers in environmental monitoring and modelling. In Arvorezinha, a 1 km2 watershed on the edge of a volcanic plateau has had tobacco, forest, and grain cultivation. Conceição is an 800 km2 watershed and, in Júlio de Castilhos, hillslopes and paired zero-order catchments represent the no-till commercial agriculture that is practiced over much of the Southern Plateau region. Last, Guarda Mor watershed is cultivated in the same agricultural setting, while located on the edge of a transition from volcanic to sedimentary rocks. At these watersheds, rainfall-runoff events were monitored for discharge, sediment yield, water quality, and overall soil/land use and management. The sediment fingerprinting technique, and erosion and deposition inventories are tools that were also used. The results obtained over the years highlight the need for monitoring studies to quantify impacts and to plan and model scenarios for conservation planning. As they are used to improve runoff and erosion modelling at the watershed scale, which are then applied for simulating the most appropriate set of soil and water conservation practices. Practices that aim at maximizing agricultural yields, while improving water quality and quantity, focusing on attenuating maximum flows, and maximizing minimum flows.
