Design of Cazenovia Creek Ice Control Structure

摘要

Cazenovia Creek, in Western new York, Is the largest tributary of the Buffalo River. Breakup-ice jams form nearly every year, and ice-jam flooding occurs in Buffalo and West Seneca every 2-3 years. A proposed ice-control struc- ture consisted of a weir with ice-retaining piers, and excavated pool, and a prepared floodway. The structure performed well during model tests, but it was not built due to cost-sharing problems, This paper describes model tests and design recommen- dations for a new ice-control structure for Cazenovia Creek. It consists of nine, 3- m tall ×1.5 -m diameter cylindrical piers that are spaced across the main channel at the same site.
