Coastal disasters due to storms and related prevention and prediction are key issues in coastal environmental management and planning. In the present study, the coupled storm surge–tide–wave model has been used for studying the effects of several factors on the storm surges in the West Korean Bay during the 1997 Winnie. The results have shown that the coupled model is capable of predicting the total water level under storm events with reasonable accuracy. The results have also shown that the river discharge plays an important role in the storm surge development. The peak surges at stations 1 and 2 located in the river estuaries were 0.2–1.5 m larger than those at the stations 3 and 4. Especially, the peak surge at the station 3 located in the Taedong River estuary was much smaller compared to those at the stations 1 and 2, due to the control of the river discharge by barrages such as the West Sea Barrage. The peak surge at the station 1 located in the Amrok River estuary was 12% larger than that at the station 2 located in the Chongchon River estuary, due to the considerable difference in the river discharges. In summary, our results have shown that integrating the coupled storm surge–tide–wave model technology with the real-time river discharge forecast is feasible for predicting the inundation under both storm surge and riverine floods for the West Korean Bay.

风暴造成的沿海灾害以及相关的预防和预测是沿海环境管理和规划中的关键问题。在本研究中，已使用风暴潮-潮-浪耦合模型研究了1997年Winnie期间若干因素对西朝鲜湾风暴潮的影响。结果表明，耦合模型能够以合理的精度预测暴雨事件下的总水位。结果还表明，河流流量在风暴潮的发展中起着重要作用。与河口3和4相比，河口1和2处的峰值波动大0.2-1.5 m。特别是，与大同河口3处的3号站相比，峰值波动小得多。车站1和2 由于诸如西海拦河坝之类的拦河坝对河流流量的控制。由于河水流量的巨大差异，位于阿姆罗克河口的第一站的峰值涌浪比位于崇川河口的第二站的峰值涌浪大12％。总而言之，我们的结果表明，将风暴潮汐-潮汐-波浪模型技术与实时河流流量预报相结合，对于预测西朝鲜湾在风暴潮和河流洪水下的淹没是可行的。
