A diploma research project from the FH Eberswalde (D) was carried out with the support of the University of Basel (CH) in Swiss canton of Graubünden. In the summer of 2004 49 springs were surveyed in this area. The research area is south of the Chur and is the catchment area of the Rabiusa or Landwasser, which empty into the Rhine. It stretches from Parpaner Rothorn till Valbella passed Churer Joch and finishes by Passugg.
Springs in the Alpine region, those in the forest and forest edge as well as above the tree line, were surveyed. This research area is identified as Alpine pasture, forestry and tourism science. Any investigated springs should be ‘nearly-natural’. Apart from a few exceptions this was achieved. The foundation of the surveys can be used to build a topographical map and a spring survey map.
Questions of the diploma work:
- Influence of altitude on spring structure
- Structure of a typical spring
- Creation of a overall concept of the regions springs
Results of the spring research for the area Rabiusa can be viewed using Mapserver-Technology.
Locating, valuing and structurally categorising ‘nearly natural’ springs in the Swiss Alpine area.
