Showing papers in "Geomorphology in 2001"

TL;DR: In this paper, the characteristics, evolution and sediment discharge during the Holocene of the deltas of two large Chinese rivers, Huanghe (Yellow River) and Changjiang (Yangtze River) are summarized.

TL;DR: In this article, the authors examined the temporal and spatial distribution of discharge and sediment load in the Yangtze River basin over a 100-year period, and found that only 50% of the discharge is derived from the upper basin, with the rest coming from the numerous tributaries of the middle and lower course.

TL;DR: Wang et al. as discussed by the authors pointed out that the deteriorating flood situation is the result of inappropriate human intervention in the natural environment and suggested that the appropriate strategy should change from "keeping the flood away" to "giving the flood way".

TL;DR: In this paper, five distinctive estuary types are identified on the basis of contemporary morphodynamics, and they are classified into three types of normally open estuaries (that maintain a semi-permanent connection with the open sea), two closed estuarial types (that are separated from the sea for long periods by a continuous supratidal barrier).

TL;DR: In this paper, the Changjiang (Yangtze) River has formed a broad tide-dominated delta at its mouth during the Holocene sea-level highstand, and three boreholes (CM97, JS98, and HQ98) were obtained from Changjiang delta plain in 1997-1998 to clarify the characteristics of tidedominated delta sediments and architecture.

TL;DR: In this article, a multiple regression model including three morphological catchment properties is used to predict total sediment yield (t year −1 ) from catchments in central Belgium, based on sedimentation rates in small flood retention ponds.

TL;DR: In this paper, the authors used a 10m Digital Elevation Model (DEM) of topography to evaluate the processes that generated fire-related debris flows in the watershed of Storm King Mountain, CO.

TL;DR: In this article, a 1.22m-wide × 9.14m-long gravel bed flume was used to investigate how far wood is transported and where it is deposited in streams.

TL;DR: In this article, the stability of a step-pool channel was investigated on the basis of measurements during a median annual flood, and it was shown that the channel is stable and the effective stress remains well below the threshold to move the large, structure-forming boulders.

TL;DR: In this article, the authors developed a consistent and efficient method for generating maps of D-d using digital terrain data, which relies on measuring hillslope flow path distance at every unchanneled site within a basin, and analyzing this field as a random space function.

TL;DR: In many catchments in southeastern Australia, alluvial stores have been the dominant source of sediments mobilised in the period since European settlement, and this has been reflected by dramatic changes to river morphology as mentioned in this paper.

TL;DR: In this paper, a survey of China's water resource management situation and its challenges for the decades ahead is presented, with a special focus on the Yangtze River basin, where the water and hydropower of this vast basin are increasingly being exploited.

TL;DR: In this paper, the authors used cosmogenic radionuclide 10 Be and 26 Al to date strath terraces along the Alaknanda River in lower Garhwal Himalaya to provide an estimate of ; 4m m a y1 for the rate of regional denudation throughout the Holocene.

TL;DR: In this paper, the authors describe a method to quickly map terrain at reconnaissance (1.250,000) and semi-detailed (1:50,000), which can be used as a basis for further land evaluation and land use planning in large territories.

TL;DR: In this paper, the authors discuss the large-scale geomorphological characteristics of the Swiss Alps based on numerical analysis of a digital elevation model and compare these to an erodibility map constructed from a geotechnical map of Switzerland and regional geomorphic studies.

TL;DR: In this paper, the location of 559 landslides in the 875 km2 catchment of the Middle Fork of the Payette River, Idaho can be predicted based on topographic attributes and a wetness index generated by the DYNWET model.

TL;DR: The geomorphology of the Martian valley networks is examined from a hydrological perspective for their compatibility with an origin by rainfall, globally higher heat flow, and localized hydrothermal systems.

TL;DR: In this paper, the watershed of the Upper-Roubion River and its main tributaries, the Soubrion and Bine Creeks, was analyzed to analyze contemporary morphological and sedimentary changes in response to a progressive decrease in bedload supply.

TL;DR: In this paper, a sequence of events involved in the formation of loess deposits, both hypothetical deposits and those of central China, Hungary, Nigeria and Tunisia, are discussed and pathways are presented, which illustrate the potential role of, and inter-relationships between, a variety of silt-generating mechanisms in formation of Loess.

TL;DR: In this paper, the authors examined the human impacts on the major hydrological processes in the Changjiang River basin, with a special focus on their influence on the discharge from the drainage basin to the sea during the dry season.

TL;DR: In this article, the authors show that thermal stress fatigue and thermal shock may be more active components of the Antarctic weathering regime than have generally been recognised; the aridity of the study area limits the role of freeze-thaw weathering.

TL;DR: In this article, a data set on soil losses and controlling factors for 58 ephemeral gullies has been collected in the Belgian loess belt from March 1997 to March 1999.

TL;DR: In this paper, a review of the major scale issues in weathering studies reveals concerns over the fundamental spatio-temporal distributions of weathering phenomena, as well as issues of upscaling microscope-based observations, and linking different scales of observations in explanations of landform development.

TL;DR: In this article, the authors proposed that the Three Gorges were cut not later than the initiation of the earliest terrace, and the seven terraces, well developed along the eastern Sichuan Basin and the three gorges, date from Early to Late Pleistocene (1.16-0.01 Ma B.P).

TL;DR: In this paper, the authors examined the evolution of the Chiangjiang River at different periods based on surveys and historical records, and found that the evolutionary process of the tidal flat is highly episodic under this general tendency of progradation.

TL;DR: In this paper, a step-backwater flow model was used to estimate the peak discharges of the GLOF and seasonal high flow floods (SHFFs) and reconstruct the hydrology and hydraulic conditions of GLOFs at 10 reaches and SHFFs at 18 reaches.

TL;DR: The configuration of the Arno and Ombrone deltas (Italy) is evaluated in this article, showing that the terminal courses of the rivers forming the rivers face the dominant wave orthogonal.

TL;DR: In this paper, a set of Late Cenozoic sediments in the Kunlun Pass area, Tibetan Plateau, China were analyzed using ESR and TL dating, and it was shown that they date from the Late Pliocene to the Early Pleistocene.

TL;DR: In this paper, a large and geographically diverse data set consisting of meandering, braiding, incising, and post-incision equilibrium streams was used in conjunction with logistic regression analysis to develop a probabilistic approach to predicting thresholds of channel pattern and instability.

TL;DR: In this article, fluorescent dyes on the reclaimed surface reveal preferred flowpaths through macropores surrounding the numerous, large rock fragments in the minesoil, indicating that infiltrated water contributes to storm runoff by the processes of throughflow and return flow.
