GIS-Based Landslide Susceptibility Modelling in Urbanized Areas: A Case Study of the Tri-City Area of Poland

This paper presents the results of landslide prediction modelling for young glacial areas performed using statistical methods. The area in question is urbanized and therefore mass wasting activity a matter interest to both local community authorities. analysis was based on 2011 ‘Register landslides prone movements with scale 1:10,000 city Gdansk’ 2012 incomplete Gdynia’. research took into account geological, geomorphological, hydrological, hydrogeological, anthropogenic conditions. susceptibility map created index. calculated indices were used create Gdansk’s susceptibility. In Gdansk, 84.50% total diagnosed belongs high class, 14.25% moderate only 1.25% low or very class. After extrapolation, data also remaining parts Tri-City area, Sopot Gdynia. difficulty extrapolating neighboring urban indicated. which had been covered by geological mapping, best obtained large number causal factors. Gdynia Sopot, index value extrapolated from when selected factors considered. Gdynia, 81.6% 15.1% 3.3% These emphasize different role some factor classes occurrence areas. resultant maps show most probable future.
