- A 3-D model of Quaternary terrace development, simulations of terrace stratigraphy and valley asymmetry : a case study for the Allier terraces (Limagne, France)
- Alluvial terrace ; Climatic variation ; France ; Heave ; Massif Central ; Model ; Quaternary ; Stratigraphy ; Tectonics ; Terrace
- Simulation results suggest that terrace stratigraphy in the study area is mainly the result of internal dynamics and climatic change. Local tectonism contributed to the development of unpaired terraces while the general regional uplift played
- a dominant role in determining terrace formation and preservation in general.

- Terraced landscapes in Slovenia
- Agriculture ; Rural area ; Slovenia ; Terrace cultivation
- Slovenia is a country of exceptionally diverse landscapes at the intersection of four major European macroregions: the Alpine, Pannonian, Dinaric, and Mediterranean regions. Terraces, which are a characteristic Mediterranean landscape element, occur
- in all landscape types, but they vary in terms of density, purpose, and current function. Terraces, which define the most characteristic terraced landscape, are most common in the Mediterranean environment. - (L'A.).
- Laboratory experiment and digital simulation of multiple fill-cut terrace formation
- Channel geometry ; Experimentation ; Fluvial processes ; Fluvial terrace ; Honshu ; Japan ; Meander ; Numerical model ; Terrace
- The formation mechanism of multiple erosional terraces which develop in the dissection process of sedimentary valley fills was investigated by laboratory experiments and computer simulations. Sequences of unpaired terraces were produced
- on experimental fan-like deposits under conditions of constant water discharge, no base-level change, and no sediment supply. The terrace formation process was investigated by relating terrace morphology to the process of lateral channel shifting accompanied
- Low uplift rates and terrace reoccupation inferred from mollusk aminostratigraphy, Coquimbo Bay area, Chile
- Aminostratigraphy ; Chile ; Marine quaternary ; Marine terrace ; Sea level ; Stratigraphy
- Mollusk aminostratigraphy of Quaternary marine terrace sediments at Coquimbo Bay, Chile, combined with recently available electron spin resonance (ESR) ages, necessitates revision of the northern Chilean relative sea-level and terrace chronology
- . Terrace reoccupation during successive high sea-level stands is inferred on the basis of litho- and aminostratigraphically defined unconformities in terrace sediments.
- Asynchronous terrace development in degrading braided channels
- Arizona ; Climatic variation ; Fluvial processes ; Fluvial terrace ; Palaeogeography ; Palaeohydrology ; Quaternary ; United States
- This paper describes a process of terrace development in rapidly degrading channels that produces a physically continuous terrace tread that consists of temporally nonsynchronous segments. Moreover, the AA. show that lower terraces developed
- in the upstream portion of a degrading channel may correlate with higher terrace surfaces developed farther down channel. The results are based upon data collected and observations made in degrading braided channels in a laboratory flume and in a degrading braided
- Spatial variability of soil properties at different scales within three terraces of the Henares River (Spain)
- Chronosequence ; Fluvial terrace ; Model ; Pedogenesis ; Soil properties ; Soria ; Spain ; Spatial variation ; Statistics
- This paper shows results obtained from the geostatistical analysis of soil properties within the terraces generated by Quaternary evolution of the Henares River incision. Stationarity is assumed provided the similar nature, origin of the parent
- material and pedogenesis of the terraces. The study examines sampling at different spatial scales to establish 1) differences among 3 selected terraces of lower, medium and upper Pleistocene age and 2) short- and medium-range variations occurring within
- the terraces.
- Terraces, uplift and climate in the Karakoram Mountains, Northern Pakistan : Karakoram intermontane basin evolution in Quaternary of the Karakoram and Himalaya.
- No simple relationship exists between terrace heights, degree of incision and terrace deformation, and the tectonic and climatic history of the area. Allocyclic processes further complicate the interpretation of terrace formation. Six main types
- of terraces are recognised by the AA : glaciofluvial, morainic, fluvial, debris, lacustrine and fan terraces.
- Evolution of Quaternary river terraces related to the uplift of the central part of the Bohemian Massif
- Bohemia ; Czech Republic ; Fluvial terrace ; Geomorphology ; Neotectonics ; Palaeogeography ; Quaternary
- Fluvial sediments in the Vltava, Berounka, Sázava and Labe valleys are preserved as extensive river terrace sequences. These accumulation terraces originated from an interaction of climate-morphogenetic and neotectonic processes in the late Cenozoic
- Cryoplanation terrace orientation in Alaska
- Alaska ; Cirque ; Cold area ; Frost action ; Geomorphometry ; Periglacial features ; Snow ; Snow line ; Terrace
- This study makes an initial step in the morphometry of landscapes containing landforms attributed to cryoplanation by examining frequency distributions of cryoplanation terrace orientation and exploring their relation with glacial cirques. Data from
- the Eagle Summit/Mastodon Dome area in interior Alaska indicate a possible relation between snowline elevation and the concentration of terrace orientation.
- Agricultural terrace evolution in Latin America
- Erosion control ; Farming system ; Farming;Agriculture ; Historical geography ; Latin America ; Mexico ; Slope ; Terrace cultivation;Terrace cropping ; Venezuela
- Field work in Venezuela and Mexico suggested to the A. that very wide terraces incrementally developed in pre-Columbian times as a result of controlled erosion from hillside cultivation more than by purposeful human design. - (DWG)
- Terrace origins : hypotheses and research strategies
- Farming system ; Farming;Agriculture ; Historical geography ; Latin America ; Research ; Slope ; Terrace cultivation;Terrace cropping
- Hypothesis is advanced that agricultural terraces in river bottoms and on hillslopes emerged over time as the result of natural incremental processes abetted by soil management techniques devised by small farmers. - (DWG)
- Marine terraces as indicators of global geoidal and hydrological changes
- Global change ; Hydrology ; Marine terrace ; Sea level ; Spatial analysis ; Terrace
- Spatial pattern analysis of marine terrace elevations from 40-30 thousand years B.P. was used to reconstruct sea level and geoid parameters during that time.
- Processes of Holocene terrace formation in a steep gravel-bed river, Nikko volcanic area, central Japan
- Flume experiments suggest that, in a breaded stream, terraces are formed from bars under erosional conditions. This paper examines these processes of terrace formation with the aid of field data on the Holocene terraces of the Nedori River

- Morphological, sedimentological and tectonic features of Diamante-M. Carpinoso marine terrace flight (Tyrrhenian coast of Northern Calabria, Italy)
- Calabria ; Coastal environment ; Glacio eustatic change ; Italy ; Marine terrace ; Neotectonics ; Pleistocene ; Quaternary ; Sea level ; Vertical movement
- Marine terrace flights resulting from the interaction of Quaternary glacio-eustatic fluctuations and tectonic uplift are a typical feature of the Tyrrhenian coast of Calabria in Southern Italy; in particular a terrace flight with four orders
- of terraces is evident in the Diamante area. The aim of this study was to define the type of tectonics that acted in the area and to determine its effects, based on morphologic, morphotectonic, sedimentologic and stratigraphic evidence.
- Fluvial terraces of the lower Susquehanna River
- Fluvial processes ; Fluvial terrace ; Geomorphogenesis ; Isostasy ; Palaeogeography ; Pennsylvania ; Stratigraphic correlation ; Stratigraphy ; United States
- Within the context of the new age control, the purposes of this paper are to: 1) identify, map and correlate fluvial terraces along the lower Susquehanna River; 2) assign ages to the terraces by downstream correlation to the fluvial stratigraphic
- seequence at the river mouth; 3) develop a model for terrace genesis on a U.S. Atlantic-type passive margin; and 4) suggest the nature, magnitude, and rates of passive margin deformation.
- Coseismic uplift of Holocene marine terraces in the Pakarae River area, eastern North Island, New Zealand
- This paper presents the first detailed terrace description and evaluation of the timing and deformation pattern for each coseismic event. The AA. describe the terrace morphology and terrace deposits at three localities in region C (determined by Ota
- et al., 1983) and report ages from six of the seven terraces at Pakarae River and from several levels at Puatai Beach and Waihau Bay.
- Terrace stratigraphy in the Tunica Hills of Louisiana
- The age and number of important fossil-producing late Pleistocene terraces in the Tunica Hills have recently become quite controversial. One hypothesis holds that only a single loess-mantled Farmdalian terrace flanks the streams in this area
- . The other maintains that there are two terraces. The youngest is considered essentially Holocene in age while the older is Sangamon in age. Radiometric and stratigraphic evidence collected for this study indicates that there are two terraces. The youngest
