Littoral Processes Study, Vicinity of Santa Ana River Mouth from Anaheim Bay to Newport Bay, California.
Abstract
The major prolems of this region include: (a) erosion of the beach immediately east of Anaheim Bay (Surfside-Sunset Beach), and (b) optimum location and temporal distribution of up to one million cu yd of material suitable for beach nourishment from the widening and deepening of the Santa Ana River flood-control project. In addition to these major problems, two associated tasks exist: (a) hydraulic design of a tidal flow system to allow for the flooding and emptying of a marsh habitat development area immediately north of the Pacific Coast Highway (on the east side of the Santa Ana River), and (b) development of design feasibility concepts for maintaining an opening at the mouth of the Santa Ana River to allow passage of tidal flow up the river to the habitat area. Complete closure of the exit of the Santa Ana River now occurs as littoral material is trapped between the jetties, particularly during the summer months when riverflow is minimal. The habitat area is being developed to mitigate the loss of 8 acres of wildlife areas resulting from the planned widening of the Santa Ana River, and to preserve 84 additional acres in response to the mandate of the Endangered Species Act. Utilization of as much of this excavation material as possible for beach nourishment purposes is highly desirable.
