Abstract: A spatial simulation model was constructed to help understand the historical changes in the Atchafalaya/Terrebonne marsh/estuarine complex in south Louisiana and to project impacts of proposed human modifications. This paper summarizes the history of the Louisiana coastal land loss problem and suggested solutions; briefly discusses the model's structure, data base, and degree of fit with historical data (these are covered more fully in previous publications); discusses the uses and implications of the model, particularly as regards the estimation of the impacts of canals and levees on coastal marsh systems; and outlines the potential interface between the model and management agencies to provide solutions to pressing coastal management problems.
