Announcing a new publication for Marine Development journal. In this research article the authors Yanping Wang, Wensheng Jiang, Xing Liu, Qi Liao, Ge Yu and Changwei Bian from Ocean University of China, Qingdao National Laboratory for Marine Science and Technology, Qingdao, China and Beijing Institute of Applied Meteorology, Beijing, China discuss estimation of future storm surge inundation and effects of the adaptation measures in Qingdao, China.

Storm surges have been the most severe marine disasters, affecting the lives and properties of people due to their high frequency and intensity. Climate change will significantly increase the severity of future storm surge disasters. Therefore, strengthening the extreme risk research on storm surge disasters under climate change is significant to protecting coastal zones.

The authors of this article applied the ADvanced CIRCulation (ADCIRC) model to the sea area surrounding Qingdao, China, to estimate the impact of climate change on storm surge and inundation induced by eight typical typhoons in current and future scenarios.

Model results were validated using the available observations. These results indicate that the storm surge caused by typhoons with different intensities and paths has various effects on the Qingdao area. Furthermore, measurement results of the storm inundation area in the future scenario revealed that, in any case, with the future rise in sea level, the typhoon intensity, the inundation area, and the storm surge intensity increase. In response to changes in the storm surge and the actual situation in Qingdao, this study emphasized that coastal flooding is caused by the storm surge. Three adaptation measure scenarios were set as follows: the current level of adaptation measures (CLA), the continuation level of adaptation measures (CA), and the enhanced level of adaptation measures (EA). Based on different scenarios, the CA will reduce most of the inundation area caused by coastal flooding compared with the CLA. EA is the most significant in reducing inundation, demonstrating a decrease in inundation of more than 50%. This research has shown that good coastal protection will reduce most coastal flooding, and building dams will be considered a significant adaptation measure.

Marine Development aims to publish research papers in all relevant disciplines related to the ocean and the sea. Its scope spans diverse domains, including but not limited to marine resource management, marine environmental conservation, marine biodiversity, fisheries management, marine energy, marine policy, and international maritime law. The journal particularly values research that explores the complex links between marine issues and broader global challenges, such as climate change, sustainable economic development, and international cooperation. As a platform for interdisciplinary knowledge exchange, the journal will enable scholars to communicate their research and promote interdisciplinary research that advances our understanding of marine issues. It welcomes original research with a multidisciplinary focus and also encourages review articles that highlight the latest research trends and those with significant global impacts.
