内容記述タイプ Abstract
内容記述 本研究は結氷河川におけるアイスジャム発生と河道形状の関係を明らかにすることを目的としている.水理模型実験を用いた既往研究では,河氷の速度,幅,厚さ,長さ,川幅の拡縮割合を用いてアイスジャムの規模を表し,アイスジャムによる河氷の速度の減衰割合を評価している.しかしながら,既往研究では支川合流の影響を考慮していない.本研究では支川合流を考慮した水理模型実験を行ない,アイスジャムの規模を表す値の適用性について検討した.さらに平面2次元不等流計算で算出したアイスジャムの規模を表す値から河氷速度の減衰割合を推定し,縦断的な河道変化に伴うアイスジャムの発生危険箇所を抽出した.

内容記述タイプ Abstract
内容記述 This study aims to clarify a relationship between the ice jam occurrence and the cross-sectional profile
of the ice-covered river. On previous studies using a hydraulic model experiment, we have expressed the
ice-jam-scale using the river ice velocity, width, thickness and length, and the river-width-reduction ratio
and evaluate the attenuation ratio of the velocity of river ice with ice jam. However, no previous study has
taken into account the effects of branch river junction. In this study we carried out hydraulic experiments
considering the effects of branch river junction and examined applicability of the ice-jam-scale. Furthermore,
we estimated the attenuation ratio of the velocity of river ice using the ice-jam-scale that we found
by the two-dimensional non-uniform flow calculation and extracted the potential ice-jam locations with
the longitudinal variation of the cross-sectional profile.
