THE USE OF GIS IN THE ANALYSIS OF THE MORPHODYNAMIC POTENTIAL IN SMALL HYDROGRAPHIC BASINS, IN SUBCARPATHIAN AREAS. CASE STUDY - RAU ALB, DAMBOVITA COUNTY, ROMANIA
Abstract
Landslides and torrential erosion are among the most common geomorphological processes manifesting in the Romanian Subcarpathians, with a very high impact on the territory. The hydrographic basin of the Rau Alb stream, a left tributary of the Dambovita River, located at the western extremity of the Subcarpathians of Curvature, in the Ialomita Subcarpathians, is subject to complex processes of degradation by surface erosion, deep erosion and landslides. The research works for the analysis of morphodynamic processes were carried out in 2019-2020, in the upper sector of the Rau Alb hydrographic basin as far as the confluence with the Barbuletu stream. The basic data used in this paper are the 1:25.000 -scale topographic maps, the 1:200.000-scale geological map made by the Geological Institute of Romania, the map of land cover Corine Land Cover 2000 (taken from the website www.land.copernicus.eu), in addition to other data on the built space (the settlement map, boundaries of administrative units – made based on Open Street Map applications). All thematic maps were processed and analysed using the Weighted Overlay Analysis method, according to which every class of parameters taken into account was reclassified into 4 classes of morphodynamic potential and experimental models were made by including them in different proportions. The resulting map shows the distribution of the general morphodynamic potential, without considering the preparatory and triggering factors of geomorphological processes, which have a dynamic that is more difficult to predict for long periods of time (torrential rainfall, changes in vegetation etc.)
