The purposes of the Galveston Harbor model study were to: (a) develop plans for relocation and stabilization of the jetty channel on an alignment and at a depth suitable for the safe passage of supertankers; (b) determine means for protecting the north jetty from the undermining action of tidal currents; (c) determine the shoaling characteristics of the relocated and deepended inner bar portion of the jetty channel, and develop plans for minimizing shoaling in the relocated channel; (d) determine the shoaling characteristics of the deepened outer bar portion of the jetty channel; and (e) determine the best locations for additional anchorage area within the jetty channel or in Bolivar Roads.

This study evaluates movable-bed physical hydraulic model predictions of sedimentation effects arising from channel realignment and deepening in Galveston Harbor entrance, Texas. Comparisons of model predictons and observed behavior for 6 years following completion of channel realignment showed that qualitative predictions of an arrest of undermining of the north jetty were correct and that the predicted relative increase in total maintenance dredging was reasonably close. The primary objective of the original study--to improve channel alignment for navigation safety--was achieved but is not addressed in this report. Detailed analysis showed that absolute model predictions of dredging volumes were somewhat low in the approach channel, essentially correct in the outer bar channel, and considerably low in the inner bar channel. Locations of scour and fill were accurately predicted for the navigation channel but volumes of the changes were underestimated by the model. Large zones of scour and fill in the entrance were approximately similar in model and prototype. Differences in model and prototype results are believed to be due to scale effects and insufficient prototype data. It is concluded that movable-bed modeling is a feasible, though difficult, technique and that steps to improve model similitude will improve similar future movable-bed model studies. (Author).
