Outburst floods in China: A review

Abstract: Outburst floods can have disastrous impacts on people, and are an important driving force in landscape change and have been studied widely on Earth. In China, although outburst floods have occurred frequently, they have been relatively little systematic studied. Here, we review outburst floods in China in terms of the characteristics, distribution, causes of dams and outburst floods. In terms of natural dams, landslides accounted for the majority (287 cases), followed by moraine dams (33 cases), which are main… Show more

“…The Jinsha River (upstream of the Yangtze River), the Lancang River, and the Nu River flow in parallel for thousands of kilometers in the southern region, which is called the "Three Rivers region." Large landslides frequently inundate these river valleys (Liu et al, 2019;Liu et al, 2021).…”

“…Outbursts of landslide lakes present severe flooding threats to downstream communities (Delaney and Evans, 2015;Ling and Evans, 2014;Dai et al, 2005;Fan et al, 2012a). Landslide dams can be formed at more diverse locations along the river (Liu et al, 2019) than other types of natural dams, such as glacier or moraine dams, which are usually located in highlands near riverheads and are far from human communities (Cook et al, 2018). Therefore, LLFs pose more serious threats to humans due to their closer distances to densely populated regions.…”

“…The volume of impoundment water and downstream channel morphology, which is site specific, determines the severity/magnitude of an LLF (Fan et al, 2012b). Landslide triggers, such as large-magnitude earthquakes and high-intensity storms, control the frequency of LLFs (Liu et al, 2019). Strong earthquakes can trigger numerous landslides within river systems and form many landslidedammed lakes (Fan et al, 2012b), the outbursts of which could accelerate the flush of postseismic landslide debris (Croissant et al, 2017).…”

“…The structural failure of these dams, oftentimes due to overtopping (Shen et al, 2020a;Shen et al, 2020b;Zheng Y et al, 2021), result to flooding that can lead to casualties and destroy downstream infrastructures (King et al, 1989;Cui et al, 2013;Zhou et al, 2013;Xiong et al, 2020). Outburst flooding events are also agents of large-scale geomorphic change (Fan et al, 2019;Liu et al, 2019;Fan et al, 2020) that influence river evolution over timescales of 10 4 -10 5 years in mountain terrains, e.g., Baimakou landslide dam (Korup, 2006;Korup et al, 2010;Walsh et al, 2012;van Gorp et al, 2016;Liu et al, 2018). A better understanding of the flooding induced by landslide dam failure is important for the prediction and mitigation this mountain disaster.…”

“…Previous statistical analysis have found that the outburst discharge of landslide dam failure is a function of the dam geometry (dam height) and dammed lake properties (water level, lake volume) (e.g., Kirkpatrick, 1977;Singh and Snorrason, 1984;Costa, 1985;Webby, 1996;Pierce et al, 2010;Peng and Zhang, 2012;Liu et al, 2019). However, landslide dam failure events often occur in mountainous areas where field measurement data are difficult to obtain.…”
