Identification of the remnant traces paleo-glaciers provides important proxies to understand response environment rapid climate changes. We present a 1:25,000 scale geomorphological map covering ∼12.5 km2 upper part Mount Bistra (North Macedonia) on basis remote sensing analyses and surveys. Particular attention is given description glacial periglacial landforms, reconstruction single glacier s...

We present the geomorphological map of northwestern part Kurdistan Region Iraq, where landscape expresses tectonic activity associated with Arabia-Eurasia convergence and Neogene climate change. These processes influenced evolution landforms fluvial pathways, major rivers Tigris, Khabur, Great Zab incise Northeastern Mesopotamia Anticlinal ridges syncline trough compose Zagros orogen. The devel...

Lunar landforms are the results of geological and geomorphic processes on lunar surface. It is very important to identify types landforms. Geomorphology scientific study origin evolution morphological planetary surfaces. Elevation relief amplitude most commonly used indices in geomorphological classification studies. Previous studies have determined elevation criteria In this paper, we focus to...

The permafrost-based geomorphological map of the Mt. Foscagno – Mt Forcellina ridge (Central Italian Alps) shows distribution permafrost probability (high, medium, low probability, and probable absence) obtained by application PERMACLIM (Guglielmin et al., 2003), a GIS-based model integrating Digital Elevation Model (DEM) topographic data Climatic DataBase (CDB) available from Automatic Weather...

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 landf...

Solifluction sheets are large-scale and extensive valley-floor valley-side landforms developed widely in the British Isles from mass-wasting of glacial periglacial sediments during late-glacial times. We describe their geographical distribution review processes that have led to development. use data Cheviot Hills, one site where sedimentology optically stimulated luminescence dating been combin...

At present, there remains uncertainty surrounding the glacial history of Fennoscandian Ice Sheet on Kola Peninsula and Russian Lapland, northwest Arctic Russia. This is attributed to lack high-resolution ice sheet-scale geomorphological data in region. paper presents 245,997 landforms a new high-resolution, map Lapland. Individual were mapped from relief-shaded renditions 2 m resolution ArcticD...

Landslides are important components of global geoheritage, but awareness their significance and value in such terms seems scanty the scientific community. normally identified among various features geological geomorphological interest, often considered a source hazard. However, they seldom as geosites part geoheritage. This paper aims at filling these gaps by highlighting importance landslides ...

Reconstructing paleoenvironmental change from glacial geologic evidence in the Himalayas has been difficult because of the lack of organic material for radiocarbon dating and the problems of correctly identifying the origin of highly dissected landforms. Studies of the contemporary glacial depositional environments, and ancient landforms and sediments in the Hunza valley (Karakoram Mountains), ...

The role of aquatic and riparian vegetation in driving morphodynamics rivers is being increasingly recognized across all river types. Here, we focus on gravel-bed rivers, where the ability to influence depends upon retention stabilization predominantly sand finer sediments build landforms within active channel. One aspect such interactions among vegetation, flows transported that has received l...
