Numerical Model for Storm Surges in Galveston Bay

A numerical scheme for computation of two-dimensional, nonlinear storm surges and tides is applied to Galveston Bay, Tex. Allowance is made for the overflow of low-lying barrier islands and for the flooding of and recession from low-lying land areas adjacent to the bay. The initial surge or tide, or both, at the seaward end of the bay outside the barrier islands is prescribed. The system has been calibrated for spring tide conditions and for the surge produced by hurricane Carla (September, 1961). Verification of the system is carried out for hurricane Cindy (September, 1963).
