| 中文摘要: |
| 本文根据江心洲左右两股汊道流速水头差引起的水面超高对其进出口断面水位进行调整处理，建立了能适应于有天然江心洲的分汊河流平面二维流场和浓度场数学模型.给出了计算实例，得到一些重要结论。 |
| 英文摘要: |
| According to freeboard surface arisen from differences of branching river current, the water level of the intake and outtake section can be adjusted. Based on this principle a numerical modeling of velocity field and concentration field for natural river with branching is established. Some important conclusions are obtained from the results of calculation. |
