Ice collar measurement and shape approximation for hydrotechnical construction

A water-transport constructions are important ones for Arctic cold climate regions. Ports and waterways in Arctic are used for seasonal delivery of goods and food. Hydraulic structures, such as ports and harbors, play a particularly important role in these regions. When designing berths and other objects in this area, it is necessary to take into account the large amount of the actions, which can be taken from the side of ice. Some of the possible ice impacts are still not reflected in the normative documentation., Ice collar may form around the structure when structures freeze without significant fluctuations in the water level. Ice collar is thicker ice around the structure. This formation can increase the load transferred by the level ice to the structure. However, ice collars are not properly described in the normative documents. Measurement of ice collars and their standardization is an important step towards the development of regulatory documentation containing methods for taking into account the impact of ice collars on structures.
