The paper presents integrated database created using the riverbed of the Kutinska River), and steep unstable as input information ground-based and remote sensing data for technogenic slopes were formed. The third stage begins after studying the changes of the stream network and the development coal mining's termination. During this stage a recultivation of of landslide processes in open coal mining areas. Remote sensing the investigated territory is performed which is still incomplete. methods and GIS technologies make it possible to identify the It is characterized by the development of periodic landslide areas with strongest manifestation of landslide processes and processes generating numerous geoecological problems. determine their spatial parameters. The advantage here is thatThe created database for the investigated processes may be of the analysis is performed on an integrated basis, and not use in landscape planning, for the needs of sustainable regional separately for the particular landscape components. development, or to the local self-governing bodies. The changes of the stream network and landslide processes over a 65-year period (1940-2006) on the territories of the land of Novi Iskur, Sofia Municipality, affected by coal mining were INTRODUCTION investigated. The development of coal mining arouses a number As a result of antropogenization and the opencast of geoecological problems, contributes to the intensification of extraction of coals the nature balance is disturbed in many erosion and landslide processes in the area and has negative b m .impact on the Kutina Pyramids natural landmark located in its regions, affected by minmsg activities. These give rlse to a immediate vicinity.number of ecological problems, which affect human life bothThe thematic database created for the purpose includes directly and indirectly. An integrated GIS is created using as archive panchromatic aerial photographs and high spatial input information ground-based and remote sensing data for resolution satellite images for various years (prior to, during, studying the changes of the stream network and the and after the exploitation period), large-scale topographic maps, development of landslide processes. The created database is data from terrain studies and GPS measurements, photos, aimed at processing and retrieval of information from aerial climatic and geologic data, and other types of information. To photos and satellite images with high spatial resolution. reveal the changes in the stream network and landslide processes Remote sensing methods and GIS technologies make it in the open coal mining areas, remote sensing methods in conjunction with geomorphologic and cartographic methods possibletodentify the areastwith strongest anifestatonrof were used. Computer-aided visual deciphering and landslide processes and determine their spatial parameters. interpretation of the high spatial resolution aerial photographs The advantage here is that the analysis is performed on an and satellite images for the aforementioned ye...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
