    Abstract

    The material point method Is adopted to simulate the runout of submarine slides and their impact on subsea Infrastructure. Parallelised code running on graphics processing units yields runtimes about 5% of those for sequential computations.

    Runout behaviour of centrifuge model tests and real case history are simulated and compared with depth-averaged methods.Different runout mechanisms are observed for different combinations of soil and seabed parameters.

    Steady force exerted by slides impacting fixed seabed infrastructure are quantified, fitting results with a hybrid model that captures effects due to Inertia, shear strength and static pressure of the sliding material.
