Abstract. Compound flooding, where the combination or successive occurrence of two more flood drivers leads to a greater impact, can exacerbate adverse consequences particularly in coastal–estuarine regions. This paper reviews practices and trends compound research synthesizes regional global findings. A systematic review is employed construct literature database 279 studies relevant flooding context. explores types events their mechanistic processes, it terminology throughout literature. Considered are six (fluvial, pluvial, coastal, groundwater, damming/dam failure, tsunami) five precursor environmental conditions (soil moisture, snow, temp/heat, fire, drought). Furthermore, this summarizes methodology study application trends, as well considers influences climate change urban environments. Finally, highlights knowledge gaps discusses implications on future practices. Our recommendations for (1) adopt consistent approaches, (2) expand geographic coverage research, (3) pursue inter-comparison projects, (4) develop modelling frameworks that better couple dynamic Earth systems, (5) design coastal infrastructure with compounding mind.

Abstract Frequent, large-scale wildfires threaten ecosystems and human livelihoods globally. To effectively quantify attribute the antecedent conditions for wildfires, a thorough understanding of Earth system dynamics is imperative. In response, we introduce SeasFire datacube, meticulously curated spatiotemporal dataset tailored global sub-seasonal to seasonal wildfire modeling via observation. The datacube consists 59 variables including climate, vegetation, oceanic indices, factors. It offers 8-day temporal resolution, 0.25° spatial covers period from 2001 2021. We showcase versatility exploring variability seasonality drivers, causal links between ocean-climate teleconnections predicting patterns across multiple timescales with Deep Learning model. have publicly released appeal scientists Machine practitioners use it an improved anticipation wildfires.

Flood variability associated with urbanization, ecological change, and climatic change is of increasing economic social concern in around Flagstaff, Arizona, where flood hydrology influenced by a biannual precipitation regime the relatively unique geologic setting at edge San Francisco Volcanic Field on southern Colorado Plateau. There has been limited long-term gauging ephemeral channels draining developed lands dry coniferous forests region, resulting spaciotemporal gap observation-based assessments large-scale flooding patterns. We present new data from over 10 years monitoring using crest stage gauge network, combined other channel records multiple agency sources, to assess inter-decadal patterns area, specific emphasis examining how various controls disturbances have altered character seasonality peak annual flows.

Our results show systematic Flagstaff-area regimes that relate topographic varied systems, response climate variations local disturbances, including urbanization and, especially, high-severity wildfire.

Mining and wildfires are both landscape disturbances that pose elevated substantial hazards to water supplies ecosystems due increased erosion transport of sediment, metals, debris downstream waters. The risk may be amplified when these occur in the same watershed. This work describes mechanisms by which intersection mining wildfire lead metal concentrations waters: (1) conveyance metal-rich ash soil surface waters, (2) dissolution dissolved metals direct contact precipitation with mine waste, (3) sediment from (4) remobilization previously deposited metal-contaminated floodplain higher postfire flood flows, (5) underground workings.

In the context of climate change, wildfires occur more frequently and significantly impact vegetation–soil–water continuum. Soil water is a critical factor for understanding wildfire occurrence predicting hazards. However, there lack specific bibliometric analysis research on mechanisms by which soil influences occurrence. Therefore, this study conducted water, aiming to understand their relationship, characteristics, future development trends. We used Bibliometrix software package in R 4.4.0, provides different methods analyzing data. A total 1585 publications were analyzed from 1990 2023. The results showed that number an overall growth trend during period, with average annual increase rate 4.4%. citations per paper exhibited pattern rapid increase, followed slow growth, then decrease. Ten highly productive authors field contributed 12.2% period. Over past 30 years, University Aveiro has consistently ranked first terms quantity. Most top ten institutions are United States, Australia, several European countries. Fifty-eight countries engage related close collaboration observed between Canada, Spain. four most keywords “wildfire”, “fire”, “water repellency”, “runoff” (with frequency 1385).
