A NUMERICAL COMPUTATION OF THE STORM SURGE OF HURRICANE CARLA 1961 IN THE GULF OF MEXICO,
Abstract
The storm surge of hurricane Carla 1961 in the Gulf of Mexico is computed by numerical integration of the dynamical equations, Input data consist of sea-level distributions of observed wind and pressure at six-hour intervals throughout the three-day period selected for the study. The computation is carried out in two steps. The first is on a rough mesh (mesh length 48 nautical miles) for the entire Gulf; bottom friction is disregarded in this step. The second is a finemesh computation (mesh length 9.6 nautical miles) on the northwestern continental shelf, where the storm surge was most prominent. Quadratic bottom friction is assumed in the latter step. The fine-mesh region is chosen so as to give good resolution in the neighborhood of Galveston, Texas. Computed variations of sea level are in good agreement with tide-gage observations in this region. (Author)
