This thesis presents the results of a study of the efficiency of a cooling pond as related to temperature decreases, residence times and flow patterns. A literature review of cooling pond design principles and operational experiences was undertaken to more accurately relate the theoretical performance relationship of model and prototype. Laboratory experiments were conducted using a model of distorted scale with a flexible simulated levee system. Flow patterns and temperature decreases are correlated with various levee arrangements and the efficiency of the overall system is defined. The pond's capability as a wastewater treatment facility is also discussed. Conclusions are made on the effect of various factors influencing performance and overall efficiency of cooling ponds. Recommendations for further study of parameters relating to cooling pond design are also made.
