The water transport/ urban development interface is considered against the background of factors involved in urban transport systems in the context of the broad field of transport geography. A typology is introduced to distinguish between land-based
and water-based forms of transport, and between inter-and intra-urban systems.

The inference that flow and form are dynamically linked is in sympathy with the own conclusions of the AA. that cluster spacing is an equilibrium condition governed by the interplay of flow resistance and sediment transport.
The aim of this study was to assess the impact of climatic change on sediment transport in the river Rhine, and on the deposition of suspended sediment on the embanked floodplains in the Netherlands. - (AGD)

Morphologic transport estimates available for a 65-km stretch of Fraser River over the period 1952-1999 provide a unique opportunity to evaluate the performance of bedload transport formulae for a large river over decadal time scales. Formulae
bedload transport predictions for the 4 formulae show that they vary between each other as well as from the morphologic transport estimates.
Several Central and West-European rivers were investigated within the framework of the SCOPE/UNEP study on Carbon transport in Major World Rivers. The rivers are sampled twice a year, i.e. in August/September at low discharge and in February/March
at high discharge. Preliminary results are presented here. The rivers Meuse and Scheldt have been sampled respectively at Heusden and Temse. (LW).
Channel adjustments, bedload transport and sediment sources in a gravel-bed river, Brenta River, Italy
Multi-scale characterization and evolution of channel forms in gravel-bed rivers
of the river in terms of bedload transport and sediment sources. The study reach was investigated using historical maps, aerial photographs, monumented cross-sections, laser altimetry data and field survey. Bedload transport rates were estimated
This paper deals with the Brenta River, a gravel-bed river strongly affected by human impact. The aims of this work are 1) to reconstruct the channel adjustments that have occurred during the last decades and 2) to analyse the present condition
by a morphological approach, which allows the construction of a sediment budget. The results should be taken into account in addressing sediment management and restoration along a dynamic and unstable river such as the Brenta.
Bedload transport processes in a braided gravel bed river model
of the experiments using steady flows and unsteady flows reveal the nature of bedload transport (BLT) processes in braided rivers, particularly regarding variability of BLT in braided rivers.
A 1:50 scale hydraulic model was designed, based on Froude number similarity and using hydrological and sediment data from a small braided gravel-bed river (the North Branch of the Ashburton River, Canterbury, New Zealand). The qualitative results
This progress report reviews the research into the processes of : 1) coarse surface layers; 2) armour versus pavement; 3) bed surface structure and sediment transport; 4) imbrication; 5) small- and medium-scale gravel bedforms; 6) gravel bedforms
