Migration from cities to suburban areas combined with industrial growth justifies hurricane protection for the Galveston Bay area. A separate model indicated two barrier schemes would protect upstream areas. Alpha barrier was located just behind the gulf beaches and Gamma barrier crossed Galveston Bay 9 miles upstream. Both schemes provide gated navigation openings across channels and gated tidal passages of sufficient capacity, located to maintain existing conditions with respect to tides , currents, salinities, and dispersion patterns. Gated tidal passages are expensive and should be held to a minimum. Diversion of Trinity River flow to Houston, which would increase fresh water to Buffalo Bayou and decrease fresh water to Trinity Bay, is proposed. A power station will pump up to 3500 cfs of cooling water from Houston Ship Channel and Tabbs Bay via Cedar Bayou to the plant and discharge into Trinity Bay. Conservation agencies questioned the effects of these diversions on salinities and dispersion patterns. Tests for normal tides were made in a 1:600-, 1:60-scale model for pre- and post-barrier and pre- and post-diversion conditions, and tides , currents , salinities , and dispersion patterns were observed. Important conclusions were : (a.) diversions from Trinity River to Houston, planned for 1980, will have no significant effects; (b.) Cedar Bayou Power Station will transport more saline and poorer quality water from Houston Ship Channel and Tabbs Bay to upper Trinity Bay; (c.) plan 1 Alpha barrier would have no significant effects on tides, currents, salinities, or dye dispersion patterns and the area of tidal passages could be reduced 20 percent without adversely affecting navigation; (d.) plan 1 Gamma barrier would cause slight reductions in tidal prism and salinities; and (e.) additional tests of revised Alpha and Gamma plans are indicated._x000D_ _x000D_ NOTE: This file is large.
