Considerations on scaling behavior in avalanche flow: Implementation in a simple mass block model

DOI: 10.1016/j.coldregions.2020.103165
Abstract: Abstract Observations of runout distances combined with velocity measurements suggest that “major” dry-mixed avalanches show a scale invariance to the total drop height HSC. This is in accordance to the proposed upper-limit envelope of the… read more here.

DOI: 10.1017/jog.2018.15
Abstract: ABSTRACT Simple models of glacier volume evolution are important in understanding features of glacier response to climate change, due to the scarcity of data adequate for running more complex models on a global scale. Two… read more here.

DOI: 10.1103/physreve.95.062304
Abstract: It has been shown in recent years that the stochastic block model is sometimes undetectable in the sparse limit, i.e., that no algorithm can identify a partition correlated with the partition used to generate an… read more here.
