沿海地区处于自然灾害的最前线--随着洪水对澳大利亚东南部部分地区的破坏，这一事实变得更加突出。

提供信息是政府帮助社区应对这些事件的最重要方式之一。这些信息旨在鼓励人们对他们所面临的风险做出更明智的决定并采取相应的行动。

但正如我们的新研究表明，仅仅提供信息是不够的。我们发现，当当局通过广播广告和小册子等被动手段提供有关自然灾害的一般信息时，大多数家庭并没有改变他们的行为。

为了确保我们的社区在面对日益恶化的自然灾害时保持弹性，政府必须找到更好的方式来传递重要的信息。

Coastal areas are at the frontline of natural hazards – a fact now thrown into sharp relief as flooding devastates parts of southeastern Australia.

Providing information is one of the most important ways governments can help communities cope with these events. Such information aims to encourage people to make more informed decisions about the risks they face and act accordingly.

But as our new research shows, simply providing information is not enough. We found when authorities deliver generic information about natural hazards via passive means, such as radio ads and brochures, most households did not change their behaviour.

To ensure our communities remain resilient in the face of worsening natural disasters, governments must find better ways to deliver important messages.

在潮汐主导的河口环境中，一系列广泛的过程决定了水动力和沉积平衡。潮汐河道可能会受到最具活力的过程的影响。因此，其地貌的变化需要持续的更新。通过海洋学调查，我们在Bahia Blanca河口（阿根廷布宜诺斯艾利斯省西南部）的Canal del Medio河段收集了现场水动力、测深和沉积学数据，以研究沉积物库的存在可能对特定河道内的潮汐流模式产生的影响。在蜿蜒的河道中发现了一个不寻常的椭圆形深冲刷孔，深度为12.60米（潮汐范围约为3米）。根据这些数据，我们发现冲刷孔的维持是可能的，因为存在一个与潮汐河岸相连的细长沙岸，作为水流的水动力障碍，导致涡流模式的改变。

A wide range of processes determine the hydrodynamics and sedimentary balance in tide-dominated estuarine environments. Tidal channels can be subject to the most energetic processes. Therefore, changes in their geomorphology require continuous updates. Through oceanographic surveys, were collected in situ hydrodynamic, bathymetric, and sedimentological data in a section of the Canal del Medio in the Bahia Blanca Estuary (southwest of the Buenos Aires Province, Argentina) to examine the possible effect that the presence of a sediment bank can have on the tidal current pattern within a specific meander. An unusual elliptical deep scour hole was detected with a depth of 12.60 m in the thalweg of the meander (tidal range is about 3 m). Based on the data, it was found that the maintenance of the scour hole is possible because of a vortex forced by the presence of an elongated sandy bank connected to the tidal channel bank that acts as a hydrodynamic barrier to the currents, inducing the modification of the meander pattern.

小岛屿发展中国家（SIDS）受到了COVID-19的影响，并对其作出了反应，这为我们提供了关于气候变化下的脆弱性以及复原力途径的线索。在此，我们通过加勒比海、太平洋和印度洋小岛屿发展中国家的案例研究来思考其中的一些经验，探讨小岛屿发展中国家如何应对COVID-19，并考虑为该流行病制定的应对机制在支持气候变化的长期复原力方面的潜力。

Small Island Developing States (SIDS) have been impacted by and responded to COVID-19 in ways that give us clues about vulnerabilities under climate change, as well as pathways to resilience. Here, we reflect on some of these experiences drawing on case study examples from the Caribbean, Pacific, and Indian Ocean SIDS, exploring how SIDS have responded to COVID-19 and considering the potential for coping mechanisms enacted for the pandemic to support long-term resilience to climate change.

传统的 "硬 "保护结构的建造是为了在陆地和海洋之间有固定的界限，保护海岸线不受侵蚀。然而，在建造这些灰色结构后，往往会出现许多副作用，在海岸线上造成的问题多于解决方案。由于海岸工事，不仅自然栖息地丧失，而且还影响到沉积物的运输和供应；往往在施工后观察到邻近地区的侵蚀，或者这些结构前面的沙滩继续被侵蚀。在未来，可以在海岸带综合管理的框架内，从更自然（基于生态系统）和可持续的角度考虑不同的方法，以获得更好的长期效果。

Traditional ‘hard’ protection structures are constructed to have fixed boundaries between land and sea and protect the coastline from erosion. However, after the construction of these grey structures, often many side effects become visible and create more problems than solutions along the coastline. Not only natural habitats are lost due to coastal fortification, but it also influences sediment transport and availability; often erosion of adjacent areas is observed after construction or sandy beaches in front of these structures continue to erode. In the future, different methods could be considered in the framework of Integrated Coastal Zone Management and in terms of more natural (ecosystem-based) and sustainable approaches for better long-term results.
