THE PURPOSE OF THE MODEL IS TO DETERMINE IF THE COST OF MAINTENANCE DREDGING CAN BE REDUCED BY PROPOSED PLANS INVOLVING CHANNEL REALIGNMENTS, PARTIAL OR COMPLETE DIKING OF CONNECTING BAYS, SEDIMENT TRAPS, DIKES IN GALVESTON BAY, LOCAL CONTRACTIONS, ENLARGEMENTS, AND OTHER REMEDIAL MEASURES. MODEL VERIFICATION TESTS WERE CONDUCTED TO MAKE CERTAIN THAT THE MODEL HYDRAULIC AND SALINITY REGIMENS WERE IN SATISFACTORY AGREEMENT WITH THOSE OF THE PROTOTYPE. THE AGREEMENTS ATTAINED ARE SATISFACTORY; THE MODEL CAN BE USED TO PREDICT BEHAVIOR OF THE PROTOTYPE.
