Urban geomorphology of the Vistula River valley in Warsaw

Using ALS LIDAR DEM and OpenStreetMap data we visualise in ArcGIS the geomorphic features of a large, lowland river which flows through area impacted by urbanisation big city – capital Poland. We present on one map main geomorphological surfaces their exact boundaries: valley edge, terrace front floodplain juxtaposed with buildings transportation corridors. identify convex aeolian fluvial landforms: dunes, levees, sandy lobes including crevasse splays, ridges between swales, bars, islands; concave erosional channels, oxbow lakes, palaeo-meanders, tributary chute channels. draw implications for flood management, geo-archaeology geo-heritage conservation. search traces extreme events Holocene, also higher terraces developed its deposition Pleistocene.
