Abstract: A general outline is given of the problems of ice in relation to human activities and constructions including winter ice – polar drift ice and ice blocks derived from glaciers. The major ice problems rise from ever-changing conditions as a result of sudden and intense weather fluctuations. Formations of sludge jams accompanied by winter storms do threaten inhabited areas. Run-off river power plants are influenced by operational disturbances especially by chocking by sludge ice. During the next few years there will be a good opportunity to study what operational disturbances will occur at such power plants in the Thjorsa at Burfell where the intake is especially designed to minimize ice disturbances. Movement and collision of glacier-derived ice blocks in areas around jokulhlaup (glacial bursts) in connection with road building is an unsolved problem. Geographical engineering ice problems related to construction of reservoirs in the highlands are pointed out.
