Book Description
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).
