Snow Avalanche Dynamics

Dear Colleagues,

A snow avalanche is a typical example of geophysical grain-flows, which are usually composed of snow particles and air. For a long period, the dynamics and structures of snow avalanches could not be investigated in detail, mainly because natural avalanches break out accidentally and precise data were usually very difficult to obtain. However, with the development of new technologies, numerous full-scale experiments have been carried out for small-to-large snow avalanches, particularly in the last decade. Further, in order to obtain detailed data and insights on the physically significant dynamical processes controlling avalanches, small scale experiments were conducted. In addition, avalanche dynamics models from a simple mass-point model to a fine full 3D method have been proposed. These approaches are of importance for avalanche risk management, for instance, the validation of dynamical models, hazard mapping, a proper design of structural protection, and the development of early warning systems.

This Special Issue invites submissions covering all aspects of avalanche dynamics: incidents report, field measurements, small scale experiments, and modeling. Topics on the mechanical properties and snow-cover properties are limited to avalanche flow dynamics, and introduction on specific avalanche event is also welcome. It is recommended that potentially-interested contributors approach the Guest Editors at an early stage about possible submissions in order to verify the appropriateness of their proposed study. If appropriate, an abstract will be requested.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
