Abstract: Hydraulic models have long been used by engineers to aid in the development of effective hydraulic structures and systems. The application of the principles of hydraulic modeling to ice-covered waters can provide an innovative design tool for solving ice control and management problems by providing a method to predict full-scale ice forces on ice control structures and to predict the full-scale behavior response due to ice-hydraulic-structure interaction. The purpose of this paper is three-fold: First, a modeling criterion for hydraulic models of ice-covered waters is presented. Hydraulic models can give reliable data only if the model is designed and operated in accordance with the appropriate scaling laws. If these scaling laws are not obeyed, the model will give erroneous results and use of the most sophisticated instrumentation and equipment will only increase the accuracy of incorrect predictions. In order for the data gathered from hydraulic models to be credible, the design and operation of the model must be shown to scale prototype conditions accurately. Secondly, a unique modeling material which exhibits hydro-mechanical similitude with prototype ice properties is described. This material is currently being used in hydraulic models of portions of the Saint Lawrence Seaway as part of the Great Lakes - Saint Lawrence Seaway Navigation Season Extension Demonstration Program. Thirdly, scaling law requirements for an ice control structure are discussed with an ice boom used as an example.
