The existing, comprehensive fixed-bed model of the Columbia River estuary was used to determine the need for rehabilitating all or part of the outer end of the existing north jetty. This jetty has seriously deteriorated during the past 25 years, and a rehabilitation program has been undertaken. Model tests were conducted to determine the effects of various stages of repair of the outer 1800 ft of the jetty on the hydraulic, salinity, and shoaling characteristics of the entrance area. Test results consist of tidal elevation measurements, current velocity measurements, salinity measurements, photographs of surface and bottom current patterns, and shoaling patterns. (Author).
