- The passive margin escarpment of south-eastern Australia has a debated but generally accepted model of propagation in which it retreated (within 40 Ma) to near its current position following rifting between Australia and New Zealand 85-100 Ma before
- present. The AA. focus on this escarpment to quantify chemical weathering rates and processes and how they may provide insight into scarp evolution and retreat. They compare chemical weathering extents and rates above and below the escarpment using a mass
- across the escarpment. Finally, the AA. quantify variations in the rates and extent of chemical weathering at the hillslope scale across the escarpment to suggest new insight into how climate differences and hillslope topography help drive landscape

- Space-for-time substitution along 3 passive margin escarpments (Blue Ridge, Western Ghats, Eastern Ghats) reveals the significance of escarpment jumps and the detachment of topographic outliers, here generically termed ‘buttes’, as key processes
- of escarpment evolution. The examples show that these continental escarpments are strongly patterned after pre-rift structural and lithological heterogeneities. As seaward sloping drainages cut into the rift margin, they extend their drainage heads in a non
- -uniform and unsteady fashion. As a result escarpments can form, be destroyed, reform, and leave topographic vestiges (buttes) of the retreating escarpment. Given the pre-rift geological heterogeneities, there are no a priori reasons why escarpment
- Use of sensitivity analysis to evaluate key factors for improving slash-and-burn cultivation systems on the Eastern Escarpment of Madagascar

- The slash-and-burn pluvial rice cultivation that predominates in the agriculture of the Eastern Escarpment of Madagascar is causing ecological degradation and is aggravating poverty. Study uses sensitivity analysis, which uses existing knowledge
- Contrôle structural de la géomorphologie de l'escarpement nord-oriental de la chaîne de montagnes Stołowe, Mts Sudety, SW Pologne
- Escarpement ; Géomorphologie ; Montagne ; Pologne ; Sudety
- Escarpment ; Geomorphology ; Mountain ; Poland ; Sudety
- The geomorphology of the north-eastern escarpment of the Stołowe mountains main plateau is highly diversified. It western section is higher, amphitheatral valley heads are of larger dimensions, and the slopes are steeper and typically concave
- in longitudinal profile. In the eastern section, the scarp is lower, inclined more gently and lacking in continuous rock cliffs. The strength of sandstone in the western section, determined using a Schmidt hammer, is greater, thereby accounting for the steepness
- of slopes. Differences in groundwater outflow between adjacent sections of the escarpment result in spatially non-uniform erosion of the scarp itself and its foreland, causing the disappearance of the lowest morphostructural horizon in the northern part

- Changing holocene snail faunas and environments along the eastern Caprock Escarpment of Texas
- Morphotectonic indices of the Eastern Wadi Araba (Dead Sea Rift, Jordan)
- Two morphotectonic indices (mountain front sinuosity, valley width to height ratio) were measured along the eastern rim of Wadi Araba, which represents the southern segment of the Dead Sea transform in Jordan. The area can be divided into three
- mountain fronts based on trend and continuity of the escarpment. The southern two fronts are controlled by two eroded boundary normal faults, while the northern front is controlled by the Dead Sea transform fault. - (NF)

- et Irkutsk. La variation irrégulière de l'humidité des substrats selon les saisons de l'année et selon la hauteur de l'escarpement de rive, la formation de glace en eux perturbent la nature monolithique du substrat, provoquent le développement de

- A morphological study of the Baie des Chaleurs area, between northern New Brunswick and the Gaspé Peninsula (eastern Canada), leads to the identification of several types of palaeolandforms in the landscapes of the northeastern Appalachians

- South Africa's most valuable source of water is the eastern escarpment region of the KwaZulu-Natal Drakensberg and Lesotho highlands. Analysis of rainfall variability trends can thus contribute to a better understanding and management of the area
- and yet no recent studies have investigated these aspects. This study assesses the 1970-2000 rainfall period using 13 stations to the east of the escarpment and presents a spatial perspective on annual rainfall totals and intra- and inter- annual

- Nearly horizontal sedimentary sequences are typically eroded into escarpments capped by resistant rock layers. These escarpments record in planform the spatial variation in erosional processes. Simulation models have been constructed of scarp
- Peasants in the eastern Andean escarpment often have plots spatially removed from each other. Although net yields are reduced 7% on average by the additional travel and transport required to tend dispersed fields, harvests from them buffer
- Main factors which influenced topography shaping in Angola are geological structures and tectonic movements. The Great Escarpment of South Africa (at least within Angola) is a tectonic feature belonging to the transitional zone between the African
- structure. The erosion-denudational topography prevails there. Eastern Angola (Congo and Okovango basins) is a vast alluvial plain made up of sandy sediments of Neogene age. As in South Africa several planation epochs can be distinguished in Angola. - (L'Ed.).
- In southern Africa, stratified, closed canopy forests are regarded as relict from former wetter phases. In the eastern Cape such forests are found on the slopes of the Great Escarpment and at one coastal site at Alexandria. This forest is anomalous

- The development of vegetation on the Winterberg escarpment
- The vegetation changes during the later Quaternary of the Winterberg escarpment area are presented. It is shown that both climatic change and human-induced change have been important influences on the development of plant communities in the region.
- Continental rifting and drainage reversal : the Clarence River of eastern Australia
- Cretaceous times onwards led to the opening of the Tasman Sea, causing the reversal and beheading of the original northwest-flowing streams and the formation of the Great Escarpment. The evolution of the Clarence River does not fit into most conventional
