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.
