PhD position: High resolution micro-scale modelling of Backward Erosion Piping

A key threat to dike stability is Backward Erosion Piping (BEP), a complex process in which seepage flow through the dike foundation progressively concentrates into internal erosion channels (“pipes”) caused by sand particle erosion, particularly during high-water events. In the worst-case scenario, such pipes can develop into breaches. Current assessment methods use overly simplified models that don’t account for the intricate physics beneath the surface. Digital Dikes addresses this critical challenge by developing advanced numerical models that capture the 3D nature of BEP and the variability of soil and water conditions. The program will train 14 young researchers to develop, apply and validate novel modelling methodologies to assess dike safety, in collaboration with industry, government, and international partners.

Internal erosion mechanisms remain poorly understood, particularly at the microscale, which limits the development of reliable m...
