A Comparative Study of Nonlinear Shallow-Water Wave Loads on a Submerged Horizontal Box
This paper is concerned with calculations of the two-dimensional nonlinear vertical and horizontal forces and overturning moment due to the unsteady flow of an inviscid, incompressible fluid over a fully-submerged horizontal, fixed box. The problem is approached on the basis of the Level I Green-Nag...
