We present a method of digital geomorphological mapping mountainous areas with legend consisting three-tiered nested hierarchy using two case study from Vorarlberg, Austria. Users can easily visualize maps in geographical information system (GIS) at the finest level 33 morphogenetic domains. Reclassification classes an automated GIS-workflow generates medium and high levels hierarchy, each tier...

this paper presents a new methodology for the zoning of littoral sand barriers on the basis oftheir groundwater dynamic responses to the local mean water level (mwl) climate. the method is based onthe comparison of the characteristic scales of the horizontal drainage and recharge processes. using theboussinesq equation and basic hydro-geomorphological parameters, this methodology identifies the...

The ruins of the Medieval castle and village El Castellar are located on an abrupt 1.2-km-long scarp Miocene gypsums, in central sector Ebro depression. remains main perched a 100 m cliff River. Considering historical geoarchaeological relevance settlement, this investigation aimed to study geomorphological paleoenvironmental context site during after settlement its later evolution, including c...

Remnants of cities and farmlands in China's hyperarid Tarim Basin indicate that environmental conditions were significantly wetter two millennia ago in a region which is barren desert today. Historical documents and age data of organic remains show that the Loulan Kingdom flourished during the Han Dynasty (206 BCE-220 CE) but was abandoned between its end and 645 CE. Previous archaeological, ge...

[1] Recession flows in a basin are controlled by the temporal evolution of its active drainage network (ADN). The geomorphological recession flow model (GRFM) assumes that both the rate of flow generation per unit ADN length (q) and the speed at which ADN heads move downstream (c) remain constant during a recession event. Thereby, it connects the power law exponent of –dQ/dt versus Q (discharge...

Cosmic ray exposure ages for formation of perched alluvial terraces and for abandonment of an alluvial/debrisflow fan on opposite sides of the Tangtse Valley (the outflow at the northwest end of Lake Panggong, which is in the Karakorum Range of Western Tibet) provide evidence of a humid period at V11.5 to V7 ka. This is consistent with other regional records and supports a controversial chronol...
