Swan River (Western Australia) from north to south. Point Walter has a protruding spit that extends up to into the river, forcing river traffic to detour around it. The river narrows between Chidley Point and Blackwall Reach, curving around Point Roe and Preston Point before narrowing into the harbour. Stirling Bridge and the Fremantle Traffic Bridge cross the river north of the rivermouth. The Swan River empties into the Indian Ocean at Fremantle Harbour. Plant and animal life found in or near the Swan-Canning Estuary include: The river was named "Swarte Swaene-Revier" by Dutch explorer, Willem de Vlamingh in 1697, after the famous black
Tacoma Narrows Bridge (1940) dimensionless Strouhal number, which depends on the body in question. For Reynolds Numbers greater than 1000, the Strouhal number is approximately equal to 0.21. In the case of the Tacoma Narrows, was approximately and was 0.20. It was thought that the Strouhal frequency was close enough to one of the natural vibration frequencies of the bridge i.e. formula_4, to cause resonance and therefore vortex-induced vibration. In the case of the Tacoma Narrows Bridge, this appears not to have been the cause of the catastrophic damage.
