    Spatial Variability of the Particle Size Composition of Overbank Floodplain Deposits (1997)
    Springer
    Water, air & soil pollution 99 (1997), S. 71-80 
    Details
    ISSN: 1573-2932
    Keywords: River floodplains ; overbank sedimentation ; floodplain deposits ; grain size composition ; spatial variability
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract An important feature of overbank floodplain deposits is the spatial variability of their particle size composition. Analysis of such spatial variability can assist in developing an improved understanding of the transport and deposition of suspended sediment on river floodplains during overbank flood events, in investigating the fate of sediment-associated contaminants and in calibrating existing floodplain sediment deposition models. The study reported in this paper investigates the spatial variability of the grain size composition of overbank floodplain deposits at different spatial scales, through analysis of surface sediment samples collected from frequently inundated floodplain sites on the Rivers Culm, Stour and Severn in the UK. Significant lateral and downstream variations in the grain size composition of the sediment deposits have been documented at the study sites, and the results obtained have been interpreted in terms of the processes governing overbank floodplain flow and sediment transport and deposition, which are influenced by a number of factors including floodplain geometry and topography.

    Investigating spatial patterns of overbank sedimentation on river floodplains (1997)
    Springer
    Water, air & soil pollution 99 (1997), S. 9-20 
    Details
    ISSN: 1573-2932
    Keywords: Floodplains ; sedimentation ; caesium-137 ; unsupported lead-210 ; overbank deposition ; deposition rates ; fallout radionuclides
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Attempts to study spatial patterns of overbank sedimentation on river floodplains commonly face important operational and sampling problems in documenting deposition rates. Recent advances in the application of fallout radionuclides (137Cs and unsupported210Pb) to the estimation of medium-term rates of overbank sedimentation offer an essentially unique opportunity to assemble detailed distributed data sets for medium term deposition rates. Such data can afford a valuable basis for investigating the complex relationship between sedimentation rates and floodplain microtopography and morphology and flow hydraulics. This paper reports the results of an investigation of the spatial pattern of overbank sedimentation rates on the floodplain of the River Culm, Devon, UK. Caesium-137 and unsupported210Pb measurements have been used to establish the general pattern of deposition rates along an 11 kilt reach and more intensive measurements have been employed to document the detailed pattern existing within a small area subject to frequent inundation. The resultant data have been used as a basis for interpreting the major controls on the observed patterns.
