The Landslides within the Lower Bic Plain(Republic of Moldova):Typology and Spatial Distribution

Summary/Abstract: The Lower Bic Plain is located in the southeast part of Moldova, occupying a total area of 2663 km². Geology, relief, climate, hydrography, vegetation and especially human intervention, which occur in this region, led to the deployment of geomorphological processes on extremely large surfaces. Among the processes prevailing on the territory of The Lower Bic are landslides, affecting about 2138,03 ha of the total area of the investigated territory. Typology analysis and spatial distribution of the landslides on the territory of the plain was conducted under a geomorphologic inventory of the affected areas by this process. For identification, mapping and analysing these processes topographic maps (scale 1:25 000), geological maps (scale 1:200 000) and ortophotoplans of 0,5 m resolution (2007 edition)were consulted, using MapInfo 9 and Arc GIS 9.3 software and also field observations. The spatial distribution of landslides reveals their higher prevalence in the NS direction with a rare spread to NW and SE. Even though many degraded areas were improved through anti-erosion work, performed until 1990, conditions have been created that led to the resumption of geomorphological processes.
