S&T Project 21051 Final Report: Hydraulic Concrete Surfaces for Water Resource Structures - Continued Collaboration

Published by Bureau of Reclamation | Department of the Interior | Catalog Last Checked: April 18, 2026 at 01:18 AM | Dataset Last Updated: August 12, 2024 at 02:37 PM
Water resource facilities operated by the Brazilian and United States Government are faced with cavitation and erosion of concrete surfaces of spillways and stilling basins and each have made many costly repairs that impact operations. The Bureau of Reclamation has been collaborating with Brazilian government companies and universities to study flow induced problems encountered at concrete surfaces in spillways and stilling basins by combining concrete materials testing with hydraulic laboratory studies. This report summarizes research efforts made to date and highlights laboratory testing in Brazilian laboratories in 2023 which culminated in a Reclamation site visit to Brazil to witness laboratory testing. The data contained within the report is owned and managed by our Brazilian collaborators.
