Abstract: The study of river ice jams has been inhibited by a lack of means to measure their thickness and its spatial variation. As a first step toward filling this gap, a remote thicknessprofiling method has been developed and used to obtain several ice jam profiles to date. Typical results are presented and compared with indirect thickness indications furnished by post-event shear wall heights. Statistical analysis provides a direct estimate of the roughness of ice jams, a quantity that also influences their severity. Limitations of the profiling method are discussed and possibilities for improvement identified.
