Arid area ; Base level ; Dating ; Desert ; Duricrust ; Fluvial terrace ; Geomorphogenesis ; Israel ; Negev ; Pediment ; Stratigraphy ; Thermoluminescence
The aims of this work are to characterize the morphostratigraphy of pediments in Makhtesh Ramon, Negev Desert; define the relations (synchronous or asynchronous) between fluvial terraces and pediment terrace staircases as a means of correlating time
Erosion processes in high mountain agricultural terraces in Peru

Paper examines the problem of changing human activities in the fragile environment of old agricultural terraces in the Central Andes of Peru. Eight experimental plots were established in the Santa Eulalia basin at elevations of 2800 m up to 3650 m
Rates of rock property changes with weathering : andesite gravel in fluvial terrace deposits in Nasuno-ga-hara, Japan
Erosion rate ; Fluvial terrace ; Honshu ; Igneous rock ; Japan ; Mineralogy ; Porosity ; Rock ; Rock mechanics ; Weathering
In order to estimate the rates of weathering-rind formation, this paper investigates andesite gravel with weathering rinds taken from dated fluvial-terrace deposits in the Nasuno-ga-hara, Central Japan. Mineralogical, chemical, physical
Desert pavement characteristics on wadi terrace and alluvial fan surfaces : Wadi Al-Bih, U.A.E. and Oman
Alluvial cone ; Arid area ; Geochronology ; Oman ; Quaternary ; Surface deposits ; Terrace ; United Arab Emirates
The aim of this work is to establish the characteristics of desert pavement development on three age-related groups of terrace surfaces in Wadi Al-Bih (United Arab Emirates and Oman). A second aim is to assess whether similar age-related pavement
characteristics are developed on alluvial fan surfaces, whose ages relative to the terrace sequence are suggested by morphostratigraphic relationships. Finally, on the basis of comparisons with other work, some suggestions are made relating to the age
Stream incision and terrace development in Frijoles Canyon, Bandelier National Monument, New Mexico, and the influence of lithology and climate
Climatic variation ; Fluvial processes ; Fluvial terrace ; Geochronology ; Lithology ; Longitudinal section ; New Mexico ; Quaternary ; Stream ; Tufa ; United States of America
The record of stream incision and terrace development in Frijoles Canyon, was investigated to examine the controls on channel evolution. Frijoles Canyon formed after deposition of the Tshirege Member of the Bandeleier Tuff at ca. 1.22 Ma, providing
excellent constraints on the time frame and initial conditions associated with evolution of the canyon. Evidence from terraces in Frijoles Canyon indicates that development of the stream profile has been strongly influenced both by climatic changes
The Nysa Kłodzka river drainage basin in the Sudeten Mts., SW Poland, preserves a complex late Cainozoic succession that includes 8 fluvial series or terraces and deposits from 2 glacial episodes as well as local volcanic rocks, slope deposits
of late Holocene channel and floodplain development and elucidated the relationship between reach- and subreach-scale channel transformation and terrace formation. Five terraced alluvial fills have been dated. The preservation of correlated terrace levels
Middle terrace deposits of the Tagus river in Alpiarça, Portugal, in relation to early human occupation
Archeological site ; Dating ; Fluvial terrace ; Palaeolithic ; Palaeosol ; Pleistocene ; Portugal ; Quaternary ; Stratigraphy ; Thermoluminescence
The stratigraphy and sedimentology of the Q3 middle terrace alluvial sequence in the lower Tagus river valley, were studied near the village of Alpiarça, approximately 40 km upstream from the estuarine area. Two main stratigraphic units were

In the western Grand Canyon, fluvial terraces and pediment surfaces, both associated with a Pleistocene basalt flow, document Quaternary aggradation and downcutting by the Colorado River, illuminate the river's response to overload and the end

This paper deals with the results of a study carried out on the lowest alluvial terrace of the Rivo d'Arco stream (Sorrento Peninsula), which terminates with an active sea cliff in the Marina di Equa area. This cliff exposes a very interesting geo
