Abstract
    The Authors, of the University of Adelaide, present a mathematical formulation for the motion of a slender ship in shallow water parallel to straight bottom contours, and derive from this a singular integral equation which determines the vorticity on the ship, together with a numerical procedure for solving this equation. Particular attention is paid to the trailing edge of the ship, to ensure that a correct solution of the equation is found. Numerical results for the cases of a bank and of a uniformly-sloping beach are provided. The effect of changing a ship's waterplane shape, and the effects of changes in local water-depth, distance to the beach or bank, beach angle, and ship's yaw are all investigated. The article provides a technique which can be used to find the effect of different bottom topographies on the motion of a ship. It shows that the results obtained from a bank suction investigation cannot always be readily used to predict the effect of another bottom topography, and that care must be taken when trying to formulate general conclusions.
