摘要

摘要将二维水动力stream_2d模型应用于阿穆尔河与泽雅河汇合处。在模拟过程中，考虑了大黑河岛附近无坝(1)和岛周围侧河道有坝(2)两种情况下的主要水流特征和可能的河道变化。模拟结果表明，大坝建设对主河道的水流集中有影响，这可能导致河流汇合处下游阿穆尔河主河道流速增加和后续侵蚀。

Two-dimensional hydrodynamic modelling of channel processes and floods characteristics at the confluence of the Amur and Zeya rivers

Abstract. Two-dimensional hydrodynamic STREAM_2D model have been applied to the confluence of Amur and Zeya rivers. Main flow characteristics and possible channel changes are considered during modeling for two scenarios – without dams near Big Heihe Island (1) and with four dams in the side channels around the island (2). Results of modeling demonstrate impact of dams construction on flow concentrating in the main channel, which can lead to increasing of flow velocities and subsequent erosion in main Amur River channel downstream the river confluence.
