  • Understanding watershed suspended sediment transport
  • This paper synthesizes a variety of methods adopted in suspended sediment monitoring, estimation and modelling for understanding sediment transport processes and determining the suspended sediment load. Methods for sediment monitoring are described
  • in terms of direct and indirect approaches. Different approaches toward the establishment of a sediment rating curve are examine thoroughly. Techniques of sediment modelling are summarized via depiction of various hydrological and sediment models
  • at the watershed scale. The paper ends with the discussion of future developments in suspended sediment studies at the watershed scale.

  • Flood-based analysis of high-magnitude sediment transport using a non-parametric method
  • Badland ; Flood ; Pyrénées ; Regression analysis ; Sediment budget ; Sediment transport ; Semi-arid area ; Spain ; Suspended load ; Watershed
  • This study aims to quantify flood-based sediment yields in 2 highly active headwater catchments in the upper Isábena River : Villacardi and Cabecera. The results are compared with the sediment delivery from a zero-order badland catchment
  • and the sediment yield at the outlet of the basin, upstream of the reservoir. A novel regression aproach is applied that allows the interpolation of intermittent measurements of suspended sediment concentrations, computes confidence intervals for these estimates
  • and enables the calculation of sediment loads.

  • Impacts of dams on the sediment flux of the Pearl River, southern China
  • China ; Dam ; Hydraulic works ; Impact ; Quantitative analysis ; Reservoir ; Sediment budget ; Sediment transport ; Southern China ; Stream ; Xi Jiang
  • Based on datasets begun in the 1950s of water and sediment flux at the main gauging stations and measured deposition rates in some reservoirs, this paper examines the impact of dam construction on the sediment flux of the Pearl River. The results
  • and conclusions show that the sediment flux of the Pearl River has shown a drastically decreasing trend since the mid-1980s, which is attributed mainly to deposition in the reservoirs. A further decrease in sediment flux into the sea is expected to occur

  • The behavior of specific sediment yield in different grain size fractions in the tributaries of the middle Yellow River as influenced by eolian and fluvial processes
  • Aeolian features ; China ; Dust storm ; Erosion ; Fluvial processes ; Grain size distribution ; Huang He ; Precipitation ; Sediment budget ; Sediment load ; Suspended load ; Watershed
  • Based on data from 35 stations on the tributaries of the Yellow River, annual specific sediment yield in 8 grain size fractions has been related to basin-averaged annual sand-dust storm days and annual precipitation to reveal the influence of eolian
  • and fluvial processes on specific sediment yield in different grain size fractions. The period from which the data were used is from 1950 to 1970 as basin-wide erosion and sediment control measures have not yet been practiced during this period, and human
  • impact on sediment producing and transporting processes was relatively small.

  • Relationships among rainfall, runoff, and suspended sediment in a small catchment with badlands
  • The Araguás Catchment of the Central Spanish Pyrenees has been monitored since 2004 to study weathering erosion, as well as the hydrological and sediment responses to rainfall in order to understand the dynamics of a badland area in a relatively
  • humid environment. This paper focuses on relationships among rainfall, runoff, and suspended sediment. One objective is to distinguish different hysteretic loops for single flood events and determine the relationships between the types of hysteresis
  • and the hydrological and sediment responses.

  • Structural composition and sediment transfer in a composite cirque glacier : Glacier de St. Sorlin, France
  • Cirque ; Fluvioglacial features ; France ; Glacier ; Glacier dynamics ; Meltwater ; Model ; Moraine ; Rhône-Alpes ; Sediment transport
  • This paper considers the links between structure, sediment transport and sediment delivery at Glacier de St. Sorlin, French Alps. The conclusion of this study is that at Glacier de St. Sorlin proglacial sediment-landform associations are subjected
  • to intense syn- and post-depositional modification by high melt-water discharges, hence their composition does not reflect that of sediments melting out at the terminus. The action of melt water limits the potential of the sedimentary record to be used

  • Sediment rating curves developed on stage and seasonal means in discharge classes for the Mellah wadi, Algeria
  • Algeria ; Rainstorm ; Regression analysis ; Sediment budget ; Sediment transport ; Suspended load ; Watershed ; Winter
  • The goal of this study is to estimate suspended sediment load in the Mellah wadi, Seybouse basin, using the sediment rating curve technique on data from a 23-year period. The analysis is based on frequent suspended sedument concentration
  • measurements during a great number of storms. Sediment transport is dominated by winter storms. A high exponent b of the power regression equation during the winter season confirms the intense geomorphic work by winter season storms caused by high intensity

  • Improving precision in sediment source and erosion process distinction in an upland catchment, south-eastern Australia
  • Australia ; Bank erosion ; Erosion ; Gully erosion ; Isotope analysis ; New South Wales ; Sediment budget ; Sedimentology ; Slope gradient ; Watershed
  • In this study Cs 137 and Pb 210 were used to determine surface and sub-surface source contributions of fine sediment in a small upland headwater catchment in the Central Tablelands region of New South Wales. The findings from this analysis
  • are employed in an adjustment procedure to better differentiate sediment source erosion processes by utilising channel survey and erosion pin data. Variability in sediment source contributions within the catchment was high, with rapid transition from hillslope
  • to channel source dominance of sediment flux with distance downstream in the study catchment.

  • An index of sediment transferring function (Fs) is applied in this study to reveal the temporal variation in the downstream sediment transfer of the Lower Yellow River. It is found that in the past 50 years, this sediment transferring function index
  • , the changing drainage basin factors have resulted in the decrease in the sediment transferring function of the Lower Yellow River.

  • A suspended sediment budget of the Yichang-Wuhan reach of the Yangtze River, China
  • Carrying capacity ; China ; Human impact ; Multiple regression ; River bed ; Sediment budget ; Stream ; Suspended load
  • The amount of the sediment deposition in the Yichan-Wuhan reach of the middle Yangtze River has been determined using the concept of sediment budget at the channel-reach scale. The fill-scour processes of the middle Yangtze River were studied during
  • the period 1956-1997 in response to the variation in sediment load and flow inputs. Multiple regression equations have been established to assess the contributions of influencing factors to the variation in sediment deposition amount in the studied river

  • Temporal changes in suspended sediment transport in a gullied loess basin : the lower Chabagou Creek on the Loess Plateau in China
  • Annual variation ; China ; Flood ; Gully erosion ; Loess ; Peak discharge ; Plateau ; Precipitation ; Seasonal variability ; Sediment transport ; Suspended load ; Watershed
  • Using a dataset up to 8 years long in the Lower Chabagou Creek, the variability in suspended sediment load at different temporal scales (within-flood variability, monthly-seasonal and annual) is analyzed in this paper. The results show
  • that, on the within-flood scale, most of the sediment peaks lag behind peak discharges, implying that slope zones are the main sediment source area; independent of the occuring sequences of the peaks of sediment and discharge, all the events could present an anti
  • -clockwise hysteresis loop resulting from the abundant material and the influence of hyperconcentrated flows on suspended sediment concentration. At monthly and seasonal scales, there is a store-release process, i.e. sediment is prepared in winter, spring
  • and late autumn, and exported in summer and early autumn. At the annual scale, the high variability in concentration and sediment yield are highly correlated with water yield, resulting from the number and magnitude of floods recorded yearly, and almost all
