抄録

<p>This study aimed to clarify the phenomenon of ice jams generated around bridge piers. The onedimensional ice jams calculation model was proposed. This model is composed of water flow, ice flow and ice jams. In order to check the accuracy of this model, we conducted an ice jam experiment. The section of this experiment waterway is compound cross-section. The time series phenomenon of ice jams generated around bridge piers was able to be investigated in the experiment. This calculation model was able to simulate water level variation by ice jams. In order to improve calculation accuracy, we understood that it was important to consider the influence of ice jams on water flow appropriately in this model.</p>
