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 deepened 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.
