Abstract:

Ice jam data collection is necessary to gain information on ice jam events, which may occur rarely and are often short-lived, but can at the same time cause large damages. An ice jam data collection program involves field data collection, review of existing hydrologic, hydraulic, meteorological, and ice records, and a search of historical records that may pertain to ice events. This report describes the development of an ice jam data collection program, the types of information to be collected, and techniques used in field ice jam data collection. Breakup jam, Freezeup jam, Velocity under ice. Data collection, Ice jam data, Frazil ice, Ice thickness.
