通过潮流泥沙及水体交换数学模型试验，模拟了茂名市水东湾综合整治工程实施后湾内流场变化、水体交换能力及泥沙淤积情况。研究结果表明，方案实施后，潮汐通道内平均流速最大可增加0.1~0.4 m/s，且湾内水体交换能力大幅提升，月交换率从现状的65%提高到86%左右。此外，由于湾内泥沙来源不足，方案实施后正常年淤积十分有限，平均年淤强仅0.15 m/a。总体而言，综合整治方案是有效的。

Based on the mathematical model test of tidal current&sediment and water exchange, the tidal currents variation, water exchange ability, and sedimentation of the regulation scenario of Shuidong Bay is simulated. The results show that after the construction of the regulation scenario, the mean speed increases with the maximum of 0.1~0.4 m/s in the tidal inlet, and the water exchange ability is increased significantly that the monthly water exchange rate increases to 86%compared to the present rate is only 65%. Besides, because the sediment supply is not abundant, the normal sedimentation is very limited after the construction, the mean annual sedimentation rate is only 0.15 m/a. In general, the comprehensive improvement scheme is effective.
