Effects of Ice Boom Geometry on Ice Capture Efficiency.
An ice boom's geometry is critical to the collectlon and retention of ice in small, fast-moving streams and rivers. Ice booms are designed to quickly form a solid ice cover much earlier than the ice cover would form naturally. Once formed, the ice cover insulates the river, eliminating the prod...
