![]() ![]() Wetlands provide a number of important and beneficial functions. The elimination or degradation of wetlands will cause a reduction of beneficial functions provided by the wetlands. Polluted waters can be conveyed off-site through connecting waterbodies. That impact could extend beyond the limits of the work site, affecting other public or private property. This program was established under Chapter 403, F.S., to protect our surface waters from degradation caused by the loss of wetlands and from pollution caused by construction activities.Īlteration of wetlands and other surface waters may have a detrimental impact on the environment. Why are dredge and fill activities regulated?ĭredging and filling in the surface waters of Florida has been regulated since the early 1970s. The surface waters regulated under the dredge and fill program include bays, bayous, sounds, estuaries, lagoons, rivers, streams, the Gulf of Mexico, the Atlantic Ocean, most natural lakes, and all waters and wetlands (natural or artificial). Filling means deposition of any material (such as sand, dock pilings or seawalls) in wetlands or other surface waters. Emphasis is placed on the choice of parameters for modelling key processes for predicting the fate of dredge plumes, including flocculation, resuspension and deposition of the sediments generated through dredging.Dredging means excavation in wetlands or other surface waters or excavation in uplands that creates wetlands or other surface waters. (iii) the required data for model parameter estimation and model validation. (i) contemporary understanding, algorithms and parameters in sediment transport models (ii) the process of testing and validating model predictions and We assess factors contributing to the accuracy in model predictions and the effectiveness of monitoring and managing the impacts during dredge operations. We also review a number of EIA modelling studies around tropical Australia associated with coastal infrastructure developments. In this review, we synthesize the current knowledge on several key processes for sediment transport modelling, and standard practice of sediment transport modelling around the world with a particular focus on the applicability to tropical marine waters off north Western Australia, and tropical Australia more broadly. ![]()
