Spatio‐temporal patterns of channel changes in response to a major flood event: the case of the Magra River (central–northern Italy)
Earth Surface Processes and Landforms - Tập 40 Số 3 - Trang 326-339 - 2015
Laura Nardi, Massimo Rinaldi
AbstractOn October 25th 2011, the Magra River (central–northern Italy) was affected by a significant flood event with an estimated return interval ranging from 30 to 200 years. This study investigates the morphological responses of the Magra River to this major flood event with the aims of (i) documenting the channel changes which occurred in r...... hiện toàn bộ
Flood hydrology and geomorphic effectiveness in the central Appalachians
Earth Surface Processes and Landforms - Tập 15 Số 2 - Trang 119-134 - 1990
Andrew J. Miller
AbstractThis paper compares hydrologic records and geomorphic effects of several historic floods in the central Appalachian region of the eastern United States. The most recent of these, occurring in November 1985, was the largest ever recorded in West Virginia, with peak discharges exceeding the estimated 500‐year discharge at eight of eleven stations in the South...... hiện toàn bộ
Influence of rock mass strength on the erosion rate of alpine cliffs
Earth Surface Processes and Landforms - Tập 34 Số 10 - Trang 1339-1352 - 2009
Jeffrey R. Moore, J. W. Sanders, W. E. Dietrich, Steven D. Glaser
AbstractCollapse of cliff faces by rockfall is a primary mode of bedrock erosion in alpine environments and exerts a first‐order control on the morphologic development of these landscapes. In this work we investigate the influence of rock mass strength on the retreat rate of alpine cliffs. To quantify rockwall competence we employed the Slope Mass Rating (SMR) geom...... hiện toàn bộ
Hyperconcentrated flows on a forested alluvial fan of eastern Canada: geomorphic characteristics, return period, and triggering scenarios
Earth Surface Processes and Landforms - Tập 39 Số 14 - Trang 1876-1887 - 2014
Marie‐Audray Ouellet, Daniel Germaın
ABSTRACTThe assessment of the dominant flow type on alluvial fans usually refers to two categories: debris‐flow fans (i.e. sediment gravity flows) and fluvial fans (i.e. fluid gravity flows). Here we report the results of combined morphometric, stratigraphic and sedimentological approaches which suggest that hyperconcentrated flows, a transitional process rheologic...... hiện toàn bộ
Trapping of airborne dust by mosses in the Negev Desert, Israel
Earth Surface Processes and Landforms - Tập 16 Số 2 - Trang 153-162 - 1991
Avinoam Danin, E. Ganor
AbstractAirborne silt and clay containing calcium carbonate, quartz, clays, marine nannoplankton, and aquatic diatoms are trapped among stems of mosses in the Negev Highlands Desert. The mosses were studied in an area with 70 mm mean annual rainfall. They grow over the particles covering them and trap additional dust as it comes, resulting in the accumulation of lo...... hiện toàn bộ
Speleothems in a north Cuban cave register sea‐level changes and Pleistocene uplift rates
Earth Surface Processes and Landforms - Tập 43 Số 11 - Trang 2313-2326 - 2018
Jo De Waele, Ilenia M. D’Angeli, Tomaso R. R. Bontognali, Paola Tuccimei, Denis Scholz, Klaus Peter Jochum, Andrea Columbu, Stefano M. Bernasconi, Joan J. Fornós, Esteban R. Grau González, Nicola Tisato
AbstractA flight of marine terraces along the Cuban coast records Quaternary sea‐level highstands and a general slowly uplifting trend during the Pleistocene. U/Th dating of these limestone terraces is difficult because fossil reef corals have been affected by open system conditions. Terrace ages are thus often based on geological and geomorphological observations....... hiện toàn bộ
Rock moisture measurements: techniques, results, and implications for weathering
Earth Surface Processes and Landforms - Tập 30 Số 3 - Trang 359-374 - 2005
Oliver Sass
AbstractRock moisture is an important factor for the intensity and distribution of frost weathering processes. However, quantitative measurements are scarce, which is partly due to the lack of reliable measurement techniques. This paper presents five different techniques for obtaining rock moisture data. While collecting rock pieces and two‐dimensional geoelectric ...... hiện toàn bộ
A case study of the processes displacing flow from the anabranching Ovens River, Victoria, Australia
Earth Surface Processes and Landforms - Tập 32 Số 14 - Trang 2120-2132 - 2007
Dean A. Judd, Ian Rutherfurd, John W. Tilleard, Robert J. Keller
AbstractAnabranching rivers have been well described and location‐for‐time models suggest that anabranches evolve through stages from channel development to eventual abandonment. Yet, there is much we do not know about the evolution of these systems. Our understanding of why anabranches evolve, how flow is displaced onto the floodplain or what propagates the scouri...... hiện toàn bộ
Multichannel rivers: their definition and classification
Earth Surface Processes and Landforms - Tập 39 Số 1 - Trang 26-37 - 2014
Paul A. Carling, John D. Jansen, Lyubov Meshkova
ABSTRACTThe etymology and historic usage of such terms as ‘anabranch’, ‘anastamose’ and ‘braided’ within river science are reviewed. Despite several decades of modern research to define river channel typologies inclusive of single channels and multiple channel networks, typologies remain ill‐conditioned and consequently ill‐defined. Conventionally employed quantita...... hiện toàn bộ
Characterization of complex fluvial systems using remote sensing of spatial and temporal water level variations in the Amazon, Congo, and Brahmaputra Rivers
Earth Surface Processes and Landforms - Tập 35 Số 3 - Trang 294-304 - 2010
Hahn Chul Jung, James Hamski, Michael Durand, D. E. Alsdorf, Faisal Hossain, Hyongki Lee, A. K. M. Azad Hossain, Khaled Hasan, Abu Saleh Khan, Ashabul Hoque
AbstractThe Surface Water and Ocean Topography (SWOT) satellite mission will provide global, space‐based estimates of water elevation, its temporal change, and its spatial slope in fluvial environments, as well as across lakes, reservoirs, wetlands, and floodplains. This paper illustrates the utility of existing remote sensing measurements of water temporal changes...... hiện toàn bộ
