| 中文摘要: |
| 本文采用Delft3D三维分层模型研究堵港蓄淡水库水体淡化过程。用浙江省漩门二期堵港蓄淡水库长历时观测资料对模型进行验证和参数率定，水位、盐度及其分层的计算结果和观测资料基本吻合;在此基础上，该模型用于预测2004～2006年漩门二期堵港蓄淡水库在设计水文条件下运行时库内水体淡化过程及其效果。计算结果表明水库表层水体受径流影响较大，盐度下降很快，致使盐度分层明显，枯水年局部表层水体会出现返咸现象；深潭底部水体淡化很慢，应采取排盐措施。 |
| 英文摘要: |
| The Delft 3D model is introduced to numerically simulate the process of water desalination in a polder reservoir for storing fresh water. The validity of the model is verified by the observation data in the early stage of impounding. On this basis the model is applied to predict the variation of water level and distribution of salinity in the reservoir in the period of 2004 to 2006 under the designed hydrological conditions. The calculation shows the salinity of surface water in reservoir is remarkably affected by the river runoff and decreases quickly in the process of reservoir impounding, but the desalination procedure at the bottom of the reservoir will be very slow. Consequently, to drain the high salinity water in the reservoir bottom by means of pumping must be considered. |
