Abstract: The authors have studied on the possibility of using the Ishikari River in Hokkaido Island as a commercial inland waterway. Hokkaido lies in a cold region, and the Ishikari River is freeze-up in winter. Therefore, any winter river navigation would require icebreaking. Towards that end, this study surveys the ice thickness along a proposed Ishikari waterway navigational channel. It also shows laboratory test data about the flexural strength of snow ice and columnar ice.
