Geohazards and Geomorphological Setting in Poznań Urban Area, Poland

This paper presents the results of geohazards mapping and evaluation their role in modifying urban landscape Poznań, Poland. Information on specific to an lowland area (river floods, flash mass movement, wind erosion) because increasing climate change was compiled into a geomorphological map. The most spatially widespread Poznań include: (a) moraine hills/uplands: erosion, floods (4.9% city area); (b) outwash plains: movement (8.6% (c) fluvial landforms: river (9.8% (d) within plains various origin: (7.6% area). Mass affecting short but numerous (and locally steep) slopes, are (16 14%, Poznań’s area, respectively). Extensive urbanisation especially expansion impervious surfaces increases high risk floods.
