Assessment of landslide hazard risks on the example of the land cadastre of Kosiv district

Abstract

The purpose of the research presented in this article is to analyse landslide hazards by assessing the impact of the natural component of factors on land use within the Kosiv district of the Ivano-Frankivsk region. The increasing number of negative consequences of landslide processes in the study area, and especially in the Carpathian region of Ukraine, requires the creation of new approaches to land resource assessment and civil engineering to reduce the negative impact of landslides on the environment and human activities. Methods. Landslide processes were studied using geophysical methods, GPS and geostatistical methods of data analysis. Based on the created mapping layer of the land cadastre and the landslide hazard map for Kosiv district, a vector analysis was performed to assess the risk in each area according to its cadastral number. Results. The environmental and geological risk of the natural component of landslide hazard factors was calculated using geoinformatics and geostatistical analysis tools with the use of QGIS. An important result of the research is the creation of landslide risk maps of land plots based on data from the State Land Cadastre using the Kadastr.Live Toolbar plugin. Scientific novelty. For the first time an analysis of the natural component of landslide hazard risks for the territory of Kosiv district was carried out as a basis for the assessment of such risks for individual cadastral zones. The regulatory and monetary assessments were clarified based on individual territories, for conducting economic activities that require hydrogeological research or changing the intended use of land.. Practical significance. By applying the methodology of dividing landslide risk assessment factors into natural and anthropogenic components, it becomes possible to identify areas within the study area with the highest probability of landslide development and activation. This method helps to study the characteristics of natural factors and is useful in assessing the risk of landslides..
