soil moisture - Opis:
- Transformation of the natural environment of human life may have different speed, depending on the number of conditions, especially the climate. There is a long−term transformation, but also the sudden changes, often having for humans the nature of disaster. An example of sudden and undesirable changes in the environment are observed in form of movements of soil on the slopes of the mountain. One of the environmental factors that determine the slope stability is the current soil moisture. Its sudden increase caused by heavy rain or spring thaw can significantly change soil physical conditions and triger landslides. Water saturation may also occur in soils of these areas, to which water from the road drainage devices flows. The aim of the study is to determine the spatial distribution of soil moisture in the outlet of the drainage facilities for forest roads in the context of changes in selected soil characteristics affecting the possibility of landslides. We selected two culverts and two open top culverts that drain the forest road in Gorce National Park. The most important for the observations was to determine the spatial distribution of soil moisture and soil moisture differences in selected locations of an outlet of the road drainage facilities in relation to the place of outlet and the unit drain line. In the analysis of measurement results, there was no significant difference between the average humidity clustered according to ‘position' and by the ‘line'. The significance of this was obtained for the average moisture grouped according to ‘depth'. This can be explained by the impermeability of land and a large decrease in the slopes in the area of research. In general, rather small soil moisture fluctuations, despite the variability of rainfall, in conjunction with significant fraction of skeleton particles, do not create conditions conducive to the formation of landslides.
