Hydraulic model of Alberni harbour Nuttall, John Blakely
Abstract
A hydraulic model of Alberni Harbour was built to study the mixing of fresh and salt water, the disposal of industrial sewage, and the result of proposed physical changes in the Harbour. The model was built to a scale of 1/1000 horizontally, and 1/84 vertically. A modified form of Lord Kelvin's tide predicting machine is used to compute the tides and thus control a pair of valves which add salt water and remove mixed water. River discharge is manually adjusted. A method of removing water samples from the operating model for chemical analysis was developed as a means of observing salinity distribution. At present the model is ready for verification and experiment.
