IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

PRELIMINARY RESULTS FROM TWO YEARS OF ICE STRESS MEASUREMENTS IN A SMALL RESERVOIR
Author : Chris Petrich , Irina S?ther , Lennart Fransson , Bj?rnar Sand , and B?rd Arntsen
Design standards for hydropower dams and other reservoir dams require ice loads to be considered. Ice stress measurements were performed in a small reservoir near Narvik, Norway in 2012/13 and 2013/14 in an effort to identify the signature of thermal ice stresses and distinguish them from mechanical stresses due, for example, to bending. Stresses observed could be related to temperature changes in the ice and indicated the combined action of thermal expansion and secondary creep. Both compressive and, to a limited extent, tensile stresses were recorded during warming and cooling periods, respectively. Stresses tended to be lowest at the periphery of the
