The final model will be linked to an oyster population dynamics model to determine the effect of channel enlargement on the oyster populations of Galveston Bay. The hydrodynamic and salinity regimes, that are the primary input for each subsequent model, are provided by a 3-dimensional finite element program. A description of this model, its verification and the evaluation of the channel enlargement will be presented. The changes in the flow and salinity field associated with the channel enlargement and the lessons learned for this application will be discussedASW,USA,Texas,Galveston Baychannel flowChannelsCrassostrea virginicaDredgingEnvironmental impactfinite element methodhydraulic engineeringmodelsoyster fisheriespopulation dynamicsQ1 01442 Population dynamicsQ1 01601 GeneralQ1 01601 Shellfish cultureQ2 02170 Nearshore dynamicsQ3 01583 Shellfish cultureQ5 01521 Mechanical and natural changesSalinityUSAUSA,Texas,Houston Ship ChannelCONF
