This study evaluates the serviceability of floating structures designed for marine cities by incorporating wave-dissipating modules. Small-scale model tests in a 2D wave flume were conducted to compare with and without these modules under different conditions (1-year 100-year return period waves). The results showed that significantly reduced vertical acceleration, reductions approximately 44~45% levels 1-year waves 54~57% waves. When topside building was included, similarly pronounced, reaching 64% 63~64% waves, respectively. also mitigated inclination (angle), reduction rates ranging from 55~77% levels, depending on presence building. These findings suggest around periphery can enhance their creating more comfortable stable environments human activities, while improving stability themselves. Future research should focus scaling up conducting field experiments validate real conditions, as well optimizing module designs structural configurations.

The present study examines perceptions and preparedness for flooding in Greece, a country increasingly impacted by natural hazards, particularly due to the effects of climate change. Despite frequent occurrence floods, public remains insufficient many areas. Through survey 1282 respondents from various regions Greece using R statistical software process analyse data, research explores relationship between individual flood risk perceptions, prior experiences, household-level preparedness. findings show most participants are aware governmental plans, but significant gap exists perceived risks actual preparedness, especially regarding insurance relocation willingness. reveal that majority management plans; however, outcomes concerning willingness relocate highlight efforts. Many expressed dissatisfaction with current measures address risks, leading diminished trust respective authorities. To enhance awareness engagement underscores importance localized communication strategies tailored different demographic groups. Given observed efforts should focus on bridging this disconnect through practical, community-driven initiatives. Recommendations include implementing targeted campaigns, promoting government transparent policies, providing financial incentives such as subsidized encourage protective actions, and, additionally, fostering community involvement disaster management, historically flood-prone regions, strengthen resilience against future events.

Coastal areas are highly dynamic environments, vulnerable to natural processes and human interventions. This study presents the first application of Integrated Vulnerability Index (ICVI) in Cyprus, focusing on two major tourism-dependent beaches, Fig Tree Bay Vrysi Beach, located along Protaras coastline. Despite their economic significance, these coastal face increasing vulnerability due intensive tourism-driven modifications dynamics, necessitating a structured assessment framework. research addresses this gap by integrating ICVI with geographical information system (GIS) analytic hierarchy process (AHP) methodologies evaluate risks environment, providing replicable approach for similar Mediterranean settings. Ten key parameters were analysed, including slope, rate coastline erosion, geomorphology, elevation, tidal range, wave height, relative sea level rise, land cover, population density, road network. The results revealed spatial variations vulnerability, 16% classified as having very high another vulnerability. Bay, which is part coastline, emerged critical hotspot its geomorphological instability, low interventions, seasonal beach infrastructure development. underscores need sustainable management practices, dune preservation, controlled development, integration into planning frameworks balance growth environmental conservation.

The study evaluates the implementation of check dams as nature-based solutions to address soil erosion, improve sediment quality, and enhance water retention in Urku Huayku ravine, located on Ilaló volcano Ecuador. Weekly samples were analysed from 2021 2023. Critical parameters measured include pH, electrical conductivity, nutrient concentrations, organic matter content. Macroinvertebrates collected assess biodiversity changes using Andean Biotic Index (ABI) Shannon Diversity Index. Results show significant improvements: quality remained neutral (average pH 7.06), while increased 0.2% 3.2% Additionally, improved, with a 355.6% increase macroinvertebrate abundance. Statistical tests confirmed positive impact quality. also identified potential areas for additional dam installations QGIS analysis, emphasising steep slopes ideal locations. This demonstrates efficacy restoration degraded ecosystems underscores their pivotal role climate change mitigation. Through enhanced storage matter, facilitated capture approximately 58% carbon. they contributed improved biodiversity.
