                                                Numerical models are increasingly important for assessing urban flooding, yet reliable input data are oftentimes hard to obtain. Taking Ho Chi Minh City as an example, this paper explores the usability and reliability of open-access data to produce preliminary risk maps that provide first insights into potential flooding hotspots. As a key novelty, a normalized flood severity index is presented which combines flood depth and duration to enhance the interpretation of hydro-numerical results.

                                                Scour depths at nine British offshore wind farms (OWFs) were analysed. Site-specific scour drivers were identified, including the relative water depth, relative median grain size, Keulegan–Carpenter number, and sediment mobility. These findings improve our understanding of scour behaviour at different scales and lay the groundwork for enhancing scour prediction frameworks at future offshore wind farms, thereby supporting the expansion of sustainable energy.

                                                Plastic pollution has negative effects on the environment. Tropical rivers around the world suffer from both plastic pollution and invasive water hyacinths. Water hyacinths grow rapidly and form dense floating mats. Using drones, cameras and AI, we show that along the Saigon river, Vietnam, the majority of floating plastic pollution is carried by water hyacinths. Better understanding water hyacinth-plastic trapping supports improving pollution monitoring and management strategies.

                                                Micro-businesses, often overlooked in adaptation research, show surprising willingness to contribute to collective adaptation despite limited finances and local support. Based on a study in Ho Chi Minh City in Vietnam, approximately 70 % are ready for awareness campaigns, and 39 % would provide financial support if costs were shared. These findings underscore the need for increased involvement of micro-businesses in local adaptation plans to enhance collective adaptive capacity.

                                                River plastic emissions into the ocean are of global concern, but the transfer dynamics between fresh water and the marine environment remain poorly understood. We developed a simple Eulerian approach to estimate the net and total plastic transport in tidal rivers. Applied to the Saigon River, Vietnam, we found that net plastic transport amounted to less than one-third of total transport, highlighting the need to better integrate tidal dynamics in plastic transport and emission models.

                                                As the adverse impacts of hydrological extremes increase in many regions of the world, a better understanding of the drivers of changes in risk and impacts is essential for effective flood and drought risk management. We present a dataset containing data of paired events, i.e. two floods or two droughts that occurred in the same area. The dataset enables comparative analyses and allows detailed context-specific assessments. Additionally, it supports the testing of socio-hydrological models.

                Short summary
                    Like many other megacities in low-elevation coastal zones, Ho Chi Minh City in southern Vietnam suffers from the convoluting impact of changing environmental stressors and rapid urbanization. This study assesses quantitative hydro-numerical results against the background of the low-regret paradigm for (1) a large-scale flood protection scheme as currently constructed and (2) the widespread implementation of small-scale rainwater detention as envisioned in the Chinese Sponge City Program.
                    Like many other megacities in low-elevation coastal zones, Ho Chi Minh City in southern Vietnam...
