Abstract: Small streams can cause severe ice-jam flooding. Ice booms can mitigate freezeup ice jams for low cost and environmental impact provided suitable low-velocity pools are available. Low-cost breakup ice-control structures also exist, although work remains to quantify their effectiveness. Ice weakening could provide effective breakup ice-jammitigation at very low cost and environmental impact. However, large natural variability in ice hydraulic conditions, lack of suitable theory and incomplete field data make it difficult to quantify their effectiveness.
