Abstract

Recent studies have revealed that breaching, rather than liquefaction, is the dominant failure process in underwater slopes of fine sand and the main driver of observed flow slides in nature. As a result, breaching is getting more attention from hydraulic and geotechnical researchers. Measurements of breaching-generated turbidity currents are substantial for understanding the interaction between the turbidity current and the slope surface, as well as for the validation of numerical models. However, these measurements are scarce in the literature. To this end, laboratory experiments are planned to be carried out in the water lab of Delft University of Technology, the Netherlands. This paper describes the special experimental setup that will be employed to obtain the required data.
