- Opis:
- The aim of this paper is to present results of the research on contemporary morphogenetic processes and landforms on an extemal waste dump of the Bełchatów Lignite Mine. The most important aspect of the research was the detennination of human impact on this transformation. The recultivation of the Bełchatów waste dump has been almost finished (except of a gypsum storage yard) and now the hill is forested. It is known as Mount Kamieńsk and is used for recreation such as skiing and biking. The research was based on geomorphological mapping. Field study was conducted in five periods, between July 2008 and September 2009. The authors showed that the linear water erosion is the main morphogenetic process acting on unpaved roads and paths - biking routes of Mount Kamieńsk. Particularly damaged, both by water erosion and by erosion caused by vehicles, are the roads on sandy ground. Information about the rate of erosion processes on roads was obtained on the basis of measurements along three selected road cross-profi les located on sandy road fragments (fig. 6). In the whole research period these roads were deepened by 0.2-0.4 m on average (fig. 7, 8, 9). On the roads localized on other grounds (not sandy) erosion caused directly by off-road vehicles was the most significant. Signs of erosion (natural and caused by vehicles) were registered on roads located on slopes as well as on flat areas. The gypsum storage yard is subject to intensive rill and gully erosion. This process was assessed indirectly be measuring accumulation rate on two small alluvial fans. The accumulation in four months period with some intense rainfall episodes was determined to be 0.07-0.125 m. The external waste dump of the Bełchatów Lignite Mine is a good example of successful recultivation of transformed landscape. Nowadays, linear erosion occurs on a very limited area, mainly in the gypsum storage yard and on roads. Erosion control devices are present only on a few road sectors. In authors' opinion the best way to preserve the "Mount Kamieńsk" roads is to cover their surface by crushed stone. It is also recommended to continue the monitoring of processes which transform the most damaged fragments of the waste dump.
