Yosemite Slough Wetlands Restoration

San Francisco, CA

The Yosemite Slough Wetlands Restoration is currently an on-going project. Yosemite Slough is part of the Candlestick Point State Park Recreational Area. The purpose of the project is to expand wetlands in the area, provide public access, and improve wildlife habitats. A previous phase of the project involved developing alternatives, estimating construction costs, and preparing a feasibility report. NCI is responsible for hydrodynamic analysis, surveying, preparing grading plans, designing public paths, preparing construction cost estimates, and preparing contract documents.


Design will consider, and dispose of as necessary, contaminated sediments in the area. The modeling study was part of the wetland restoration project and includes both the hydrodynamic simulation and sediment transport simulation for the Yosemite Canal and South Basin. The RMA2 model within the Surface-Water Modeling System (SMS) was used for the hydrodynamic simulation and the SED2D model was applied for the sediment transport simulation.

Coastal Engineering and Water Quality Study

Bahia de los Sueños, Baja California, Mexico

NCI evaluated the feasibility of six waterfront development alternatives for a real estate development at the Bahia de los Sueños, Baja California, Mexico. The six alternatives consisted of an open deep water lagoon, open shallow water lagoon, closed salt water lagoon, open mooring facility, docking facilities at “El Manglito”, and RO seawater desalination plant discharge. The coastal analysis and water quality study performed included: oceanographic measurements and a bathymetric and beach survey; tidal harmonics analysis and tidal predictions; wind wave hindcasting; wave transformation using Mike 21-PMS; hurricane wave generation and transformation using Mike 21-SW; littoral processes, shoreline impact and beach erosion analysis; lagoon water circulation modeling using RMA2; lagoon water quality modeling using RMA4; evaluation of lagoon water quality based on water exchange time and residence time; tidal inlet hydrodynamic analysis to optimize the inlet design; modeling salinity distribution adjacent to the desalination discharge using RMA4 to optimize outfall placement and desalination plant design; analysis of open mooring facilities and docking facilities; and conceptual design of entrance channel jetties to the lagoon.
