This study examines a broad range of ice problems at river confluence sites, grouping the sites into four categories. Weighted criteria were used to select two representative sites from each category for detailed analysis. This report describes the ice problems at the eight selected sites, focusing on the relationship between channel geometry, hydrometeorological factors, and the historical record of ice events. For each site, tentative structural solutions are proposed.
