Summary The method for three‐dimensional storm surge computation proposed by Heaps is modified by removing the bottom frictional stress from the vertical eigenfunction expansion. The stress is applied externally on each vertical column of fluid. Calculations on a simplified model show that the technique does not alter the response of the sea from that determined by Heaps’ method. The modification allows the bottom frictional stress to be expressed as an arbitrary function of horizontal velocity rather than the linear function necessitated previously.
