A previously verified hybrid modeling system coupled physical and numerical models of the Kings BayCumberland Sound estuarine system was used to investigate hydrodynamic and sedimentation variations associated with Trident channel expansion. Although not an explicit objective of the modeling efforts, models to result in higher high-water and midtide level elevations in both physical and numerical models. Variations were close to, but greater than, model detection limits. Comparison of low-water elevations between models was inconsistent. This appendix specifically addresses the issue of tidal changes in a compact format. Pertinent information is compared with field observations and analytical considerations. Based on the presented information, it is concluded that tide range will probably not change as a result of Trident channel improvements. Mean water level in Cumberland Sound may increase a small amount, less than the normal annual variation in mean sea level. It will be extremely difficult to detect any change until data have been collected for several years.
