We conducted a 3-year study designed to examine the relationship between disturbance from military land use and stream physical and organic matter variables within 12 small (<5.5 km2) Southeastern Plains catchments at the Fort Benning Military Installation, Georgia, USA. Primary land-use categories were based on percentages of bare ground and road cover and nonforested land (grasslands, sparse ...

Tai is a family of related languages and dialects, a subgroup of the Tai-Kadai languages, spoken by more than 85 million speakers in southern China and Southeast Asia. This paper uses GIS to map the spatial distribution of Tai toponyms (Muang, Chiang and Viang) and analyzes their relationship with terrain characteristics. In Tai, Muang means flat ‘‘basin’’, Chiang means ‘‘town’’, and Viang prov...

Slope instability research and susceptibility mapping is a fundamental component of hazard management in decreasing the risk of living with landslides. Landslide susceptibility is defined as the proneness of the terrain to produce slope failures and susceptibility is usually expressed in a cartographic way. The Dena city in Iran is a landslide prone zone because of its own characteristics inclu...

The relative rates of erosion by rivers and glaciers, and the topographic effects of these two different styles of erosion, remain outstanding problems in geomorphology. We use a quantitative description of local fluvial landscapes to estimate how glaciated landscapes might look now had glaciers not developed. This indicates the landscape modification attributable to glacial erosion. We present...

In recent years, applications and analyses based on slope units have become increasingly widespread. Compared with grid units, can better represent terrain features boundaries allow a more complete view of the morphology Earth’s surface. Maps also offer significant improvements for disaster prediction analysis land resources. Therefore, we need reasonable method unit classification. Although so...

Uncertainties about landscape evolution under cold, nonglacial conditions raise a question fundamental to periglacial geomorphology: what and where are landscapes? To answer this, with an emphasis on lowland areas, the present study distinguishes between characteristic polygenetic landscapes, considers how complete is footprint of periglaciation? Using conceptual framework sensitivity change, a...
