Summary: This study investigated the impact of glacial isostatic adjustment on the routing of Missoula floods and landscape evolution. The results showed that the floods could have traversed and eroded two major tracts of the Channeled Scabland around 18 thousand years ago, but glacial isostatic adjustment limited the flow into one of the tracts at 15.5 thousand years ago. The partitioning of flow between tracts was influenced by landscape tilting.

Summary: Bedrock erosion should be considered when estimating paleo-discharge in flood-carved canyons, as high-water marks may overestimate the depth of paleo-floods. Our study quantified paleo-flood discharges in different phases of canyon incision using hydraulic modeling and geologic evidence. The results indicate that deep canyons can be formed by outburst floods with lower discharges and flow depths than those required to inundate high-water marks.

Summary: We report the first numerical ages for megaflood deposits in the GLM basin by applying the novel OSL rock surface dating technique. The ages obtained for cobbles collected from three locations along one bar's transport direction are 16.5 +/- 0.9, 18.5 +/- 1.4, and 21.7 +/- 1.1 ka. These results demonstrate the potential of these techniques in providing reliable chronologies for paleofloods and other high-energy depositional events.

Summary: This study examines GLOF events in glacierized areas of the Cordilleras of Peru and Bolivia using high-resolution satellite and aerial imagery, as well as documentary data. A total of 160 GLOF events from 151 individual sites are characterized and analyzed, tripling the number of previously reported events. The study provides important statistics on these events for regional GLOF hazard identification and assessment.

Summary: Glacial lake outburst flood (GLOF) is a major natural disaster in the Qinghai-Tibetan Plateau that can cause significant damage to surrounding areas. Analyzing the evolution of glacial lakes using radar and optical image data is crucial for preventing similar disasters in the future.

Summary: Lakes in arctic permafrost landscapes can experience rapid drainage and cause downstream flood events. A monitoring study of a high-drainage-potential lake in northern Alaska revealed that it drained within 12 hours, generating a significant flood. The study also estimated future flood hazards from other lakes in the region and highlighted the importance of understanding the impact of lakes on arctic hydrology and landscape evolution.

Summary: The study demonstrates that successive landslides pose a threat to river channels, potentially triggering more severe floods. Analysis of two flooding events shows that the effective dam height significantly influences peak discharge of floods, exhibiting a linear relationship. Additionally, the narrowing effects of river sections during landslide processes also increase flood risk.

Summary: Landslide-dammed lake outburst floods pose serious threats to mountainous areas and downstream regions. The study of Diexi ancient landslide-dammed lake reveals that the floods in this area were the largest in the Upper Minjiang River Valley since the Late Pleistocene, with geomorphic impacts lasting for tens of thousands of years.

Summary: This paper proposes a prediction model for the possibility of glacial lake outburst floods (GLOFs) and emphasizes the selection of easily available predictors. Using the Geodetector, four predictors were detected and analyzed. The probability prediction model achieved an overall accuracy of 86%, correctly classifying 78% of drained lakes and 90% of undrained lakes. The results provide practical and efficient references for local government and people.

Summary: Glacial lake outburst floods (GLOFs) are a major natural hazard in certain mountainous areas, such as the Himalayan region, with potential catastrophic consequences. This study developed a new framework using open data and high-performance hydrodynamic modeling to assess the potential impact of GLOFs, focusing on the Tsho Rolpa glacial lake in Nepal. The results showed the potential damages and loss of lives that could occur in the worst-case GLOF scenario considered.

Summary: Small Arctic coastal catchments and lagoon systems are highly vulnerable to climate change due to glacial retreat and the development of glacial lakes and drainage systems. By analyzing remote sensing data, we were able to observe the rate of glacial recession, the formation of glacial lakes, vegetation response to climate change, and the impact of environmental shifts on shoreline and lagoon stability.

Summary: This research investigates the impacts of climate change-induced Glacial Lake Outburst Floods (GLOFs) on agriculture in the Gilgit-Baltistan region of Pakistan. The study finds that farmers have suffered from the damage to their fertile land and crops caused by recent GLOFs, resulting in low crop yield and agricultural income. Current adaptation practices are inadequate to cope with the increasing climate risks, thus urgent support and interventions are needed to enhance the resilience of mountain communities to future GLOFs.

Summary: Retrieving information from various sources about past flood events in Badajoz, Spain has allowed researchers to reconstruct a series of 37 catastrophic floods of the Guadiana River since 1500 CE, revealing strong seasonality and a notable difference in flood frequency between 19th-20th centuries and 16th-18th centuries. Evaluation of long-term precipitation trends and atmospheric circulation patterns (NAO and EA modes) from 1851-1985 suggests that extreme floods in this period were associated with consecutive months of higher-than-usual precipitation, influenced by unusual values of the NAO and EA modes.
