    loess gully erosion
    shear strength and natural moisture content in loess
    Opis:
    The article presents the problem of intense erosion in loess gullies in the locality Kazimierz Dolny. Primary reasons for such a quick development of gullies are: lithogenetic and physical-mechanical characteristics of loess, geomorphological and climatic conditions of the region and also human activity. Gully erosion impedes rural activity and communication in the area and causes considerable damages to local roads. In one of the loess gullies typical for the region, called ,,Opolska Droga” near Kwaskowa Góra, physical and mechanical parameters were examined by field and laboratory tests. The results revealed a clear correlation: shear strength of loess considerably decreases when its natural moisture content increases. What is also important, the structure of loess — loose soil skeleton mostly built of quartz and small amount of cementing clay particles — is prone to erosion. Thus, its adverse susceptibility to influence of water occurs to be primary reason of intensive gully erosion development in the area of Nałęczów Plateau . Additionally, geomorphological and climatic conditions, together with human rural activity (often using gullies as local ways of road transport) result in faster erosion development and, in effect, they lead to disastrous results like those that took place in the region during extreme rainfalls some years ago. Any stabilizing engineering works within loess gullies should be preceded by appropriately designed system for the regulation of run-off in the drainage area.

    Opis:
    The development of landslides in southern Poland caused financial and public substantial losses at the turn of centuries. It became an impulse for developing of the counteraction standardized system against harmful effects of mass movements. A reconstruction of destroyed objects was the first step after every landslide event. The issue of mass movements turned up at the Polish legislation after 2000. Landslides were regarded as act of natural processes, while numerous reactivating of the landslides were regarded as state of natural disasters. An obligation of taking landslides into account in the land-use planning was established. An obligation of monitoring and registering of landslides was imposed also on self-government units. At the same time assumptions of the Landslide Counteracting System (LCS; SOPO in Polish) project were developed. The aim of the Project is to collect and archiving in a standardized format results of investigations of the landslide.Within the frame of the LCS project on seventy five percent of the Carpathian area landslide inventory has been made, while still sixty landslides are currently monitored. Results of the work are archived in on-line available LCS database. The detailed data about landslines is accessible to the local authorities. This data is a primary source of information essential for raising fouds needed for stabilization, restoration and shifting of the destroyed public infrastructure. This data is also a tool for keping the spatial sustainable policy on the local level.
