Using the dimensionless equations of motion, continuity and heat transfer, similarity criteria for the flow of heated water over and essentially stagnant and colder impoundment are presented. In most cases it will be impossible to satisfy all criteria. Some acceptable approximations are therefore analyzed. Turbulent flow in the model, matching of reduced gravitational forces and surface heat loss as well as sufficient size of the model are considered to be most essential modeling requirements.
