“…The debris flows investigations at DDFORS were covering various aspects: mechanism of debris flow formation (Cui et al 2005;Chen et al 2017;Kang & Hu 1990), debris flow movement (Chen et al 2007;Guo et al 2020;Shu et al 2007), debris flow deposition (Wang et al 2007), analysis of various parameters of the debris flows, such as velocity (Li et al 2012) and relation between the dimensions of the granular material and the characteristics of the released debris flows , effects of topography, landslides and erosion, precipitation on debris flows formation (Chen et al 2005;Guo et al 2013;Tian 1987;Tian et al 2020), debris flow forecasting (Hu et al 2011;Liu et al 2012), debris flow mitigation engineering (Lin et al 2007), disaster evaluation and management of debris flow (Liu et al 2009;Liu et al 2002), direct observations of formation of debris flow (Cui et al 2007;Huang et al 2015;Fu et al 2006;Li et al 1983;Tian et al 2007), direct observation of debris flow dynamics (Kang & Hu 1990), statics and rheology of debris flows Li et al 1983), hazard and risk assessment of debris flows (Cui et al 2013;Wei et al 2010;Zhu & Tang 1996).…”

The requirements of the debris flows’ parameters assessments vary from country to country. They are based on different theoretical and empirical constructions and are validated by data from different regions. This makes difficult comparison of the reported results on estimated debris flows activity and extent. The Russian normative documents for the debris flows’ parameters calculations are based on empirically-measured parameters in wide range of geological and climatic conditions at the territory of former USSR, but still not cover all the possible conditions of debris flow formation. An attempt was made to check applicability of the Russian empirical constructions for the conditions of the debris flows formation in Yunnan, China, where unique long-term dataset of debris flows characteristics is collected by the Dongchuan Debris Flow Observation and Research Station. The results show, that in general the accepted in Russia methodology of calculation of the parameters of debris flows of certain probability corresponded well to the observed in Dongchuan debris flows characteristics. Some discrepancies (in the average debris flow depth) can be explained by unknown exact return period of the actually observed debris flows. This allowed to conclude that the presently adopted empirical dependencies based on country-wide (USSR) empirical data can be extrapolated up to the monsoon climate and geological conditions of Yunnan province.
