This study proposes a comprehensive approach to managing post-eruption floods through river engineering and irrigation management. And non-structural mitigation. The research methodology involves collecting secondary data from related agencies and primary data through interviews and observations of river conditions and irrigation systems. And the community. The study emphasizes the use of river engineering techniques to develop effective structural flood control measures. It also advocates for a combination of structural and non-structural interventions to stabilize river flows and reduce disaster impacts. Structural interventions such as sediment control using sabo dams and the design of irrigation intakes adapted to Mount Marapi’s specific conditions aim to minimize sediment transport, enhance agricultural irrigation systems, and improve overall regional resilience. Furthermore, the study provides policy-relevant insights to support government decision-making and offers a foundation for strengthening community resilience to volcanic hazards.","source":"CrossRef","year":2026,"language":"en","subjects":null,"doi":"10.1186/s40677-025-00356-2","url":"https://doi.org/10.1186/s40677-025-00356-2","pdf_url":"https://link.springer.com/content/pdf/10.1186/s40677-025-00356-2.pdf","is_open_access":true,"published_at":"","score":70},{"id":"ss_4a8ae57e17f03656e4fcd18cddfadc8317af8829","title":"Research Progress and Perspectives on Prevention and Control Technologies for Coal‒Rock‒Gas Composite Dynamic Disasters: New Types of Induced Classifications, Discriminant Criteria, and Structural Control Schemes","authors":[{"name":"Junwen Zhang"},{"name":"Xu-yang Bai"},{"name":"Zhixiang Song"},{"name":"Yang Zhang"},{"name":"Xu Dong"},{"name":"Shaokang Wu"},{"name":"Chaorui Xing"},{"name":"Xian Li"},{"name":"Weizheng Xu"},{"name":"Suilin Zhang"}],"abstract":"","source":"Semantic Scholar","year":2025,"language":"en","subjects":null,"doi":"10.1007/s00603-025-04657-8","url":"https://www.semanticscholar.org/paper/4a8ae57e17f03656e4fcd18cddfadc8317af8829","is_open_access":true,"citations":11,"published_at":"","score":69.33},{"id":"crossref_10.31224/5043","title":"Engineering Resilience in Fragile Ecosystems: Technological and Geological Strategies to Mitigate Himalayan Disasters","authors":[{"name":"Sudhakar Geruganti"}],"abstract":"The Himalayan region, particularly Uttarakhand, faces recurrent ecological disasters due to unregulated construction, tourism-driven urbanization, and climate change.

We then review the limited evidence for physical and mental health, and behavioural impacts, resulting from volcanic emissions entering aircraft. Serious health risks are considered low for healthy individuals, but respiratory irritation is likely for a high exposure scenario to sulfur dioxide (SO2). Asthmatics are particularly sensitive to SO2, with even relatively low, short exposures, potentially resulting in severe respiratory impacts.

Due to the high intensity of seismic activities, it is essential to perform seismic hazard analysis by considering local site effects. Therefore, this study aimed to analyze the peak ground acceleration (PGA) value based on the earthquake scenario of May 27, 2006, with a magnitude of 6.3, which occurred on the eastern side of the Opak Fault. Methods The study was conducted in the southern part of the Progo River, the Special Region of Yogyakarta, using 31 boreholes and 18 microtremor measurement points. The analysis was carried out using four methods: Kanai (In: Proceeding of Japan Earthquake Engineering Symposium 1–4, 1966) equation using microtremor data, deterministic equations with Ground Motion Prediction Equations Next Generations Attenuation West 2 (GMPE NGA West 2), Kanno et al (Bull Seismol Soc Am 96:879–897, 2006) attenuation equation, and probabilistic method referring to the Indonesian Seismic code. Results Results indicated that the highest value of PGA was obtained using the deterministic GMPE NGA West 2 weighted attenuation equation, which varied from 0.475 to 0.549 g. Meanwhile, Kanno et al (Bull Seismol Soc Am 96:879–897, 2006) attenuation equation resulted in values ranging from 0.266 to 0.394 g. In contrast, PGA values obtained through microtremor measurement resulted in a smaller value, in the range of 0.126–0.214 g. Probabilistic analysis in the study area produces values ranging from 0.373 to 0.450 g. Conclusion The location on the central side of the Progo River shows a lower PGA value than the other sides. PGA values will tend to be higher at locations near the earthquake source. The low PGA value that resulted from microtremor analysis was due to the consideration of local site effects in determining earthquake parameters in the study area. Determining the seismic hazard analysis method in infrastructure planning requires a comprehensive analysis by considering various parameters, such as the planning and design objectives, the location proximity to earthquake sources, historical seismic conditions, and the presence of the local site effects.","source":"DOAJ","year":2025,"language":"","subjects":["Disasters and engineering","Environmental sciences"],"doi":"10.1186/s40677-025-00310-2","url":"https://doi.org/10.1186/s40677-025-00310-2","is_open_access":true,"published_at":"","score":69},{"id":"doaj_Urban+Flood+Zoning+Using+an+Integrated+Hydrological-Hydraulic+Watershed+Modeling+Approach%2C+Case+Study%3A+Districts+21+and+22+of+Tehran","title":"Urban Flood Zoning Using an Integrated Hydrological-Hydraulic Watershed Modeling Approach, Case Study: Districts 21 and 22 of Tehran","authors":[{"name":"Ali Nasiri"},{"name":"Esmaeil Salimi"},{"name":"Morteza Delfan Azari"},{"name":"Jafar Yazdi"},{"name":"Mohammad Shahsawandi"}],"abstract":"Flood zoning has extensive applications in flood management and is considered one of the fundamental and critical pieces of information in flood risk management. Flood zoning in urban areas is much more challenging than modeling in floodplain and river areas due to the two-dimensional nature of the flow and, on the other hand, the density of urban features such as buildings, streets, boulevards, and public pathways. In this study, flood zoning for districts 21 and 22 of Tehran was conducted under the current conditions, where the area is almost devoid of surface water collection channels, using a physically-based rainfall-runoff model and two-dimensional hydraulic routing which is the novelty aspect of the article. For this purpose, the HEC-HMS model was used to estimate the runoff from the mountains, and the MIKE model was used to simulate urban rainfall-runoff. According to the modeling results, the areas affected by a 50-year flood event were identified using an integrated modeling approach in districts 21 and 22, covering 8% of these areas. In these areas, the maximum flood depth is 11.8 meters in Vardavard river and the highest speed is 4.5 meters per second at the beginning of Hashemzadeh street (south of Kharrazi highway). The results indicate that in the event of extreme events such as a 50-year rainfall, a significant portion of the highways and main communication arteries of Tehran leading westward would be disrupted, and traffic would be impossible. Moreover, various land uses would fall within the flood zone, and due to the absence of a surface water network, waterlogging conditions throughout districts 21 and 22 of Tehran are predictable. Therefore, the development of a surface water collection network is one of the main priorities for reducing flood risk in these areas.","source":"DOAJ","year":2025,"language":"","subjects":["Risk in industry.

The novelty of this research is in determining the effect of tide on the lowland drainage system for forestry in a coastal tropical region and the impact of river cleaning on flood management. Five monitoring stations were set up along the Lebong Hitam river and its primary channels to observe flow characteristics, water level, and bathymetry. The results show how the tide effects water level in the river and the adjacent drainage area with Eucalyptus plantations. Cleaning of the river had a significant effect on each station and increased the discharge and velocity by more than five times and reduced the water depth by more than 40%. In light of this research, it can be concluded that the cleaning up process improves flood risk management by decreasing the water level and increasing the discharge and velocity at each of the upstream stations. The cleaning did not have a significant effect on downstream sections of the river where sea levels control the water level in the river to a large extent. The work provides an analysis of tidal river and provides recommendations for current and future drainage and water management.","source":"DOAJ","year":2025,"language":"","subjects":["River protective works.

The article then provides examples of UAV applications in different natural disaster scenarios, including monitoring, early warning, post-disaster assessment and ecological restoration in floods, mudslides and earthquakes. In flood monitoring, UAVs equipped with various sensors, such as multi-spectral sensors and infrared thermal imagers, can quickly scan flood-prone areas and transmit data in real time for timely warning and rescue. In mudslide monitoring, drones can collect data such as surface temperature, soil moisture and vegetation health to help identify signs of potential danger. In earthquake monitoring, drones can provide high-resolution images and video to assess earthquake damage and the condition of infrastructure.

The North Pacific Oscillation (NPO), a primary atmospheric variability over the midlatitude, is a well-known trigger for ENSO events, but the physical linkage is not yet fully understood. Based on observational analyses, in Part I, we proposed a new mechanism that the NPO-related wave activity flux (WAF) could directly induce the equatorial wind anomalies in both upper and lower levels. In this study, we substantiate the impacts of the WAF on tropical circulations using climate models participating in the Coupled Model Intercomparison Project phases 5 and 6 (CMIP5/6). We found that the intensity of the southward WAF over the central Pacific is a paramount factor resulting in intermodel diversity in simulating the NPO–ENSO linkage. By classifying the models into two groups of strong and weak meridional WAF (MWAF), we reveal that the strong MWAF models simulate stronger upper- and lower-level equatorial winds and precipitation anomalies that facilitate the ENSO in subsequent winter. We also reveal that the magnitude of the MWAF is closely related to the model’s climatological meridional wind and meridional shear of climatological zonal wind, emphasizing the role of systematic bias on the ENSO simulation. A comparison of the MWAF impact and seasonal footprinting mechanism demonstrates the dominant influence of the MWAF in determining the diversity of NPO–ENSO relationships.","source":"DOAJ","year":2023,"language":"","subjects":["Environmental sciences","Meteorology.

Through a comparison with generally accepted urban flooding management practices, we (the authors) identified that a lack of surface water runoff management considerations (i.e., missing a major drainage system in urban stormwater system) and inadequate local mitigation are the primary causes of urban flooding problems in China, which in turn is rooted in the planning stage of a city's development. Following identification of the primary causes for the problems, we propose the development of master drainage plans (MDPs) for the concerned cities or regions as the first effective step to mitigate the serious urban flooding problems facing many cities today. An MDP would provide necessary elements to develop a major drainage system for the city's stormwater system and allow for an accurate calculation of parameters necessary for installation of adequate local mitigations. Lessons learned in this study should be useful for China's administrative agencies and professionals while they try to find solutions to their urban flooding problems and beneficial to other nations facing rapid urban development in the future or with existing urban flooding threats.","source":"DOAJ","year":2022,"language":"","subjects":["River protective works.
