Meteorological Conditions Causing Major Ice Jam Formation and Flooding on the Ottauquechee River, Vermont

摘要

This report discusses wintertime meteorological conditions that can induce rapid ice breakup, ice jam formation and subsequent flooding. These conditions, described for the Ottauquechee River in Vermont, should be representative of those for similar unregulated river systems in northern temperature regions. Summer flood conditions are compared to those during winter floods, when river ice is the main impediment to water flow. Comparisons are made for total precipitation, stage height and the synoptic meteorological situations. (Author)
