Abstract


An efficient computer program for predicting wave runup on beach profiles is presented. The solution is derived through the IBM 370/165 of the Computing Center, University of Florida. The wave runup data utilized in this study is based on the laboratory- derived curve obtained from the experimental work of Saville, and expressed as linear regression; the historical storm frequency data is furnished by National Oceanic and Atmospheric Administration; and the surveyed beach profile is supplied by the field program of Coastal and Oceanographic Engineering Laboratory, University of Florida. A broad spectrum of waves are selected to simulate hurricanes approaching the coast. The results thus obtained should provide useful guidelines in establishing the Coastal Construction Setback Line, and to the design criterion of Coastal Structures. i
