| # avaFilisur1 | ||
|
|
||
| ## Event [23022012_1] | ||
|
|
||
| ### Changelog | ||
| - V1 - Initial data assembly (05-12-2025) | ||
|
|
||
| ### General description | ||
| Based on Feistl et al. 2014 | ||
|
|
||
| - Location: Filisur, Switzerland | ||
| - Date: 23.02.2012 | ||
| - Elevation: Release area at 1320 m a.s.l, runout at 1080 m a.s.l | ||
| - Slope Angle, release to runout: 50-25° | ||
| - Release Volume: 1080 m³ | ||
| - Terrain features (upper part/track/runout): channeled/unchanneled/unchanneled | ||
| - Forest strucure (upperpart/track/runout): no forest/open/dense | ||
| - approx. 300 stems/ha, tree groups with low-hanging branches | ||
| - mixed tree age | ||
| - Avalanche Type: wet snow avalanche | ||
| - Temperature (dry/moist/wet): wet | ||
| - Key Field Observations: | ||
| - Wedge-shaped deposits formed behind groups of trees and at branches low to the ground. | ||
| - Main stopping mechanism was "jamming" of snow between tree groups. | ||
|
|
||
| ### Available data | ||
| Source CRS: EPSG:21781 | ||
| Final CRS: EPSG:2056 | ||
|
|
||
| - release area (avaFilisur1_release_area.gpkg) | ||
| - no documented thickness | ||
| - Feistl et al. 2014 used a standardized thickness of 1m for their modelling process | ||
| - forest area (avaFilisur1_forest_area.gpkg) | ||
| - polygons categorized based on their forest density: | ||
| - "open" | ||
| - "dense" | ||

There was a problem hiding this comment. was there any information provided on how these classes are defined? |
||
| - deposition area (avaFilisur1_deposition_area.gpkg) | ||
| - no documented thickness | ||
| - measurement points (avaFilisur1_measurement_points.gpkg) | ||
| - measured snow heights in the area of interest | ||

There was a problem hiding this comment. there are many different entries in the attribute table, please add column name for measured snow height |
||
|
|
||
| A digital elevation model (DEM) can be found at: https://www.swisstopo.admin.ch/de/hoehenmodell-swissalti3d | ||
| - Use the DEM for the region "Bergün Filisur (GR) in 2x2m. | ||
| - If two tiles are necessary, don´t forget to merge them before modelling. | ||
|

There was a problem hiding this comment. if no thickness provided, how is this defined? |

| - Terrain features (upper part/track/runout): channeled/unchanneled/unchanneled | ||||||
| - Forest strucure (upperpart/track/runout): no forest/open/dense | ||||||
| - approx. 500 stems/ha, tree groups with low-hanging branches | ||||||
| - mixed tree age | ||||||
| - Avalanche Type: wet snow avalanche | ||||||
| - Temperature (dry/moist/wet): wet | ||||||
| - Key Field Observations: | ||||||
| - Most avalanche mass was stopped at the forest edges, resulting in large wedge-shaped deposits along the sides of the main flow channel. | ||||||
| - The main avalanche channel was largely open and not forested. | ||||||
