Austrian glacier inventory 1969 (G I)

The Austrian glacier inventory 1969 was compiled from airborne photogrammetry dating from September and October 1969. It includes not only area and surface elevation, but also a number of other parameters as aspect, maximum and minimum elevation, position, ablation and accumulation area. The dataset published here are the orginal results. In course of the compilation of the second Austrian glacier inventory, the photogrammetric data partly has been reanalysed. While in this data set snow areas connected to the glaciers and snow patches in the upper parts of the glacier have not been added to the glacier area, the second glacier inventory included the snow patches.

The function of the secondary lining in the New Austrian Tunnelling Method

The decision to build the Secondary Lining in Route Tunnels which are perforated using the New Austrian Tunnelling Method does not generally depend on reasons of structural strength. The paper discusses the implications of the issue as well as the pros and cons of the current alternative courses of action.
