Abstract: Longitudinal dispersion is the spreading of suspended or dissolved substances caused by the combined action of differential advection and lateral mixing. Tracer tests in many rivers under open-water conditions have indicated ...

Abstract: Lack of field data on the thickness and roughness of river ice jams inhibits reliable calibration of ice jam models and can result in erroneous evaluation of important physical parameters. Detailed thickness data that have ...

Abstract: Following a brief account of the development of ice jam stability theories since the 1960s, inconsistencies in their interpretation for practical applications are identified. In particular, the widely used “bell-shaped ...

Abstract: The granular mass theory of river ice jams is extended to their downstream transition as a means of improving understanding of conditions at jam toe. The theory is coupled with the equations of motion under, and seepage ...

Abstract: Merritt, B.C. has a history of suffering damages from ice-jam and open-water floods. The most damaging flood on record happened in the city in 1991 due to an ice jam on the Coldwater River. A numerical ice-jam model is ...

Abstract: Bridges can impede the passage of river ice during the breakup event and promote formation of ice jams, with adverse socioeconomic and ecological impacts. Design for ice passage at bridges has largely been empirical and ...
