“…Note, however, that the previous theoretical models developed for estimating gouge depths (i.e. [15][16][17][18][19][20][21][22]) are purely deterministic; thus, neglecting the variations in soil properties and utilizing deterministic "mean" (or "extreme" in some cases) values.…”

“…Further, [18,19] considered the soil deformation ahead of the berg keel, assuming two-dimensional plane strain and relying on plasticity theory. In [20] a model of the grounding berg in sandy soils was developed based on experimental work that incorporates passive soil resistance on the front and sides of the berg and sliding resistance on the bottom.…”

A simplified model of the motion of a grounding iceberg for determining the gouge depth into the seabed is proposed. Specifically, taking into account uncertainties relating to the soil strength, a nonlinear stochastic differential equation governing the evolution of the gouge length/depth in time is derived. Further, a recently developed Wiener path integral (WPI) based approach for solving approximately the nonlinear stochastic differential equation is employed; thus, circumventing computationally demanding Monte Carlo based simulations and rendering the approach potentially useful for preliminary design applications. The accuracy/reliability of the approach is demonstrated via comparisons with pertinent Monte Carlo simulation (MCS) data.
