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.

ESTIMATION OF COMPOSITE ROUGHNESS VALUES DURING River, lake, and reservoir ice-COVER BREAKUP
Author : Soheil Ghareh Aghaji Zare PhD Candidate Dep. of Civil Engineering, Faculty of Engineering, University of Ottawa, Ottawa, ON, Canada Soheil.Zare@Uottawa.ca Stephanie Moore
For rivers in cold winter climates, a roughness coefficient needs to be calculated for the ice covered condition, which is a combination of top (ice) and bottom (river bed) resistance coefficients. This coefficient is usually called the ?composite roughness?. The composite roughness coefficient varies throughout a winter as a complicated function of River, lake, and reservoir ice processes. For example, during River, lake, and reservoir ice break-up the accumulation of fragmented ice can lead to channel blockage in some locations through a process called ?ice jam formation?. The composite roughness value is difficult to estimate in such highly unsteady situations, thus field data are
