Effect of antecedent conditions on frozen ground floors. Research technical completion report, project A-045-IDA Item Info

Predicting frozen ground occurrences can be helpful in preventing flood damage in areas that are subject to winter floods. Discriminant analysis was used to study frozen and unfrozen ground runoff events for four watersheds in the Pacific Northwest. Part of the discriminant procedure was used to choose a set of meteorological factors for each area that can distinguish between frozen and unfrozen ground runoff events. These variables were then used to define a system to classify other past or future runoff events. The occurrence of a frozen ground runoff event is dependent on the combination of several meteorological factors interacting together rather than on the influence of one single variable such as the average minimum air temperature. This methodology proved successful for two of the watersheds studied. It was found that a unique set of variables could be used for classification, depending on which watershed is being analyzed.
