Identification of Hazard and Risk for Glacial Lakes in the Nepal Himalaya Using Satellite Imagery from 2000-2015
Glacial lakes in the Nepal Himalaya can threaten downstream communities and have large socio-economic consequences if an outburst flood occurs. This study identified 131 glacial lakes in Nepal in 2015 that are greater than 0.1 km2 and performed a first-pass hazard and risk assessment for each lake. The hazard assessment included mass entering the lake, the moraine stability, and how lake expans...
متن کاملDelft University of Technology Compound simulation of fluvial floods and storm surges in a global coupled river- coast flood model Model development and its application to 2007 Cyclone Sidr in Bangladesh
Water-related disasters, such as fluvial floods and cyclonic storm surges, are a major concern in the world’s mega-delta regions. Furthermore, the simultaneous occurrence of extreme discharges from rivers and storm surges could exacerbate flood risk, compared to when they occur separately. Hence, it is of great importance to assess the compound risks of fluvial and coastal floods at a large sca...
متن کاملMagnitudes and implications of peak discharges from glacial Lake Missoula
New field evidence and discharge calculation procedures provide new estimates of maximum late Pleistocene glacial Lake Missoula flood discharges for two important reaches along the flood route. Within the Spokane Valley, near the point of release, the peak discharge probably exceeded 17 ± 3 million m-sec. Downstream at Wallula Gap, a major point of flow convergence, peak discharge was about 10 ...
متن کاملCorrigendum: A global reanalysis of storm surges and extreme sea levels
Extreme sea levels, caused by storm surges and high tides, can have devastating societal impacts. To effectively protect our coasts, global information on coastal flooding is needed. Here we present the first global reanalysis of storm surges and extreme sea levels (GTSR data set) based on hydrodynamic modelling. GTSR covers the entire world's coastline and consists of time series of tides and ...
متن کاملImpact of climate change on New York City’s coastal flood hazard: Increasing flood heights from the preindustrial to 2300 CE
The flood hazard in New York City depends on both storm surges and rising sea levels. We combine modeled storm surges with probabilistic sea-level rise projections to assess future coastal inundation in New York City from the preindustrial era through 2300 CE. The storm surges are derived from large sets of synthetic tropical cyclones, downscaled from RCP8.5 simulations from three CMIP5 models....
