Abstract: This study aimed to clarify the phenomenon of ice jams generated at the bridge piers place. The one-dimensional ice jams calculation model was built. The composition of this model is water flow, ice flow and ice jams. In order to check the accuracy of this model, we conducted an ice jam experiment. Experimental waterway has set up the channel of low-water and flood. The study clarified the following. The time series phenomenon of ice jams generated at the bridge piers place was able to be expressed in the experiment. This calculation model can express water level variation by ice jams. Furthermore, in order to raise calculation accuracy, we understood that it was important to consider the influence of ice jams on water flow appropriately in this model.
