Descripción
The reliable prediction of breach erosion processes is essential for the effective risk management of both dams and levees. In recent years, a variety of research efforts have improved our knowledge of erosion processes, however, the main focus of larger scale tests and model validation has tended to focus on finer, cohesive soils and the associated head cutting process. Similar understanding and model validation is needed for dams and levees constructed from coarser and mixed materials, with a clearer overview of when breach erosion changes from head-cut through surface erosion to slumping of rockfill. This paper presents a program of research planned by EDF which will investigate (i) how macro erosion processes change in relation to soil type and state, (ii) the validity of soil erosion relationships used for coarser and mixed grained erosion and (iii) the performance of breach models in predicting the breaching processes. This research will combine laboratory testing at UPM (~1m scale tests) and CNR (~2m scale tests) with large scale field tests (3-4m high) to be undertaken at a new test facility constructed in the River Ebro catchment near Zaragoza. The work will also combine breach model performance validation through a program of international collaboration.
