WLS Report 40: Pre-projekt: Evaluation of the effect of the blast furnace sand on the surface discharge of skiing slopes and alpine meadows in steep positions; on behalf of VOEST ALPINE STAHL DONAWITZ (VASD)
Abstract
Blast furnace sand, applied as fertilizers on skiing slopes/alpine meadows, may have effects on the quality and the covering of the vegetation. At the same time, the fertilizer can influence the soil characteristics as such. In the course of this project, rainfall simulations were made on six sample areas, three of which are skiing slopes, and the other three alpine meadows. In each test, one of these was used as reference surface (zero-version). The other two surfaces received different fertilization. For each sample area, five sprinkler units, each of them on a rainfall plot of four square metres, were used to chart the chart the small-scale variability of the soil. As part of this, the rainfall simulation design which had been developed at the department was used. Hydrologic parameters were determined on the basis of the collected data. The accompanying vegetation investigations of a sample area contained 2 recordings after Braun-Blanquet (25m¿) and 4 recordings after Londo on intensive sample plots (1m¿). The selection of the sample areas should guaranty homogeneity within the sample areas and comparability of the sample areas among themselves. The sample surfaces were marked out fixedly in the area so as to ensure repetitions of the experiments at the same location.
