  • In this paper, the AA. have analysed 3 key river dynamic relevant parameters, namely basic hydrologic parameters, sediment regime, and planview and cross section changes of the Mura River in Slovenia. They have obtained all available historical maps
  • and hydrological data, determined present sediment granulometry along the river and analysed changes in river morphology. The purpose of the study was to detect boundary conditions of morphodynamic processes in the Mura River in Slovenia as the first phase
  • of the River Scaling Concept (RSC)

  • This study addresses the quantification of the Amazon River sediment budget which has been assessed by looking at data from a suspended sediment discharge monitoring network and remote sensing estimates derived from MODIS spaceborne sensor. Both
  • field and satellite-derived estimates of the sediment concentration of the Amazon River are combined to get an uninterrupted monthly average suspended sediment discharge from 1995 to 2007. Unlike the water discharge which exhibits a steady trend over
  • The impact of environmental changes on the sediment loads of Norwegian rivers
  • The aim of this paper is to discuss some examples where detailed measurements of the sediment load have been made during extreme events. A selection of rivers representing the range of sediment yields and processes in various parts of Norway has
  • been studied in sediment monitoring programmes carried out by the Norwegian Water Resources and Energy Directorate. The combined effects of climate change and human impact on sediment transport in rivers appear to enhance downstream sediment delivery.
  • The work reported in this contribution used a novel modelling framework to assess the impact of projected change in farming by 2015 on the relative input of the agricultural sector to the total suspended sediment load delivered to all rivers across
  • delivered to all rivers. Results suggested that the agricultural sector dominates present day (year 2000) sediment inputs to rivers. Key limitations of the integrated modelling approach are discussed.
  • Preliminary modelling of sediment production and delivery in the Xihanshui River basin, Gansu, China
  • Sediment production following severe wildfire and post-fire salvage logging in the Rocky Mountain headwaters of the Oldman River Basin, Alberta
