Laboratory and Field Tests of a Wire Mesh Frazil Collector

Frazil ice jams on rivers cause problems that range from slowing commercial river traffic to widespread flooding. One of the accepted techniques of controlling frazil ice jams has been to retain the frazil ice in a location where it will not harm the environment using dams or weirs. In the interest...

Description
Summary:Frazil ice jams on rivers cause problems that range from slowing commercial river traffic to widespread flooding. One of the accepted techniques of controlling frazil ice jams has been to retain the frazil ice in a location where it will not harm the environment using dams or weirs. In the interest of developing an inexpensive ice control structure, a series of laboratory and field test were conducted using different wire mesh structures as a dam to determine which type of wire mesh best retains ice and what the optimum orientation of that mesh should be. A material such as chain link fence fabric would collect and retain the ice, but proper bed preparation must be done to prevent bed scour. Further study is required to determine the optimum mesh size.
