Abstract: The California State Lands Commission (SLC) requested US Army Engineer Waterways Experiment Station (WES), Coastal Engineering Research Center (CERC), to conduct engineering studies for technical and environmental assessment of two proposals to enhance wetlands at the Bolsa Chica estuary. Purposes of tidal circulation simulations were to ascertain hydrodynamic effects of proposed developments on Huntington Harbour and existing muted and non-muted wetlands, and determine hydrodynamic features of proposed wetland enhancement regions. Purposes of transport simulations and water quality assessment included evaluations of present water supply under existing conditions, and quality of water to be provided with proposed entrance channel concepts and wetland enhancements, in terms of water quality parameters and water parcel residence times.
