| Summary: | The city of Salmon, Idaho, is affected by flooding resulting from a frazil ice jam, known as the Deadwater jam, which forms annually on the Salmon River. Because the river has considerable environmental, economic, aesthetic, and recreational value, an innovative approach to frazil ice control is needed. The steep slope and turbulence of the river also add to ice control design constraints. Past investigations have examined a number of different methods to control the ice. This report documents two years of testing of an experimental ice formation boom located upstream from the city of Salmon. The observations show that boom configuration is an important factor in ice capture efficiency, and that conventional boom siting criteria may be modified under certain conditions. |
