This manual presents guidance for the planning, design, construction, operation and maintenance of ice control and ice suppression measures. All Corps of Engineer projects subjected to freezing temperatures have ice problems such as: ice buildup on lock walls, hydropower intakes, and lock approaches; accumulation in navigation channels; ice passage over spillways that scours the downstream channel; and ice damage to shore structures and shoreline, etc. The Army Corps of Engineers experience in ice engineering is applicable to much civilian civil engineering, and ice control measures should be considered for both new and existing projects to improve their operation and safety in cold regions. This manual discusses ice formation processes, physical properties and potential solutions to associated problems.ANFO is a mixture of ammonium nitrate fertilizer and fuel oil.
