A project to divert the freshwater riverflows into West Matagorda Bay is under construction. Its main objective is to increase the productivity of the bay. A tow simulation study to address the navigation issues raised by industry was conducted on the ship simulator at the U.S. Army Engineer Waterways Experiment Station. The study included simulations of the crosscurrents from the Colorado River with and without the diversion channel, as well as the tidal currents from three proposed navigation bypass channels. The study had three purposes. One was to determine if the diversion of the riverflow into the channel to Matagorda Bay will have a negative impact on tows crossing the Colorado River between the locks. The second purpose was to determine whether tidal flows may cause navigation problems for GIWW traffic in the vicinity of the navigation bypass channel. The third purpose was to determine at what frequency critical flow conditions will occur and develop operating procedures to minimize the impacts of these critical flows. The investigation was conducted in two phases to determine: (a) the safe operational limits of crosscurrent conditions, and (b) the length of time during cycles that these limits are exceeded.
