this issue by providing velocity and boundary shear stress data over a range of discharges from a sequence of 4 pools and 3 riffles in the River Rede, Northumberland.
Dating the culmination of river aggradation at the end of the last glaciation using distal tephra compositions, eastern North Island, New Zealand
An extensive terrace in the Waipaoa valley, eastern North Island, is underlain by at least 10 m of coarse, aggradational, river gravels. Tephra or tephric layers occurring in the lower cover beds were investigated at 5 sites using a combination
of stratigraphy, mineralogy, and the major element composition of glass shards together with discriminant function analysis (DFA). Discussion of the results. The downcutting represents a major change in river dynamics and is most likely the response to climatic
Estimation of temporally averaged sediment delivery ratio using aggradational terraces in headwater catchments of the Waipoa River, North Island, New Zealand
The AA. estimate temporally averaged SDRs within 7 neighbouring tributary catchments in the headwaters of the Waipoa River, North Island, New Zealand. Channels are generally degrading in these catchments, and gully erosion is by far the dominant
on the basis of catchment area, channel bed slope and gully area.

The AA. analyze the historical trends in channel pattern and the contemporary downstream changes in channel geometry, grain size, and gradient in the gravel bed, proglacial Sunwapta River, Alberta. The rational equations incorporate the effect
Monte Carlo simulations of a two-dimensional depth-averaged distributed bed-roughness flow model, TELEMAC-2D, are used to model a detailed tracer dispersion test in a complex reach of the River Severn in the Generalized Likelihood Uncertainty

Periglacial cover-beds on the Swiss Plateau : indicators of soil, climate and landscape evolution during the Late Quaternary
The AA. contribute to the ongoing debate on cover-beds and soils by presenting results from the Swiss Alpine Foreland. In this region, layered soil profiles have already been mentioned, but no systematic investigations of this phenomenon exists
to date. They emphasize on cover-bed-sequences on glacial deposits of varying ages to get clues on the chronology of various layers.
Particle travel distances and bed and sediment compositions associated with rain-impacted flows
Laboratory experiments were performed with rain of uniform drop size impacting flows over non-cohesive beds of uniform sized sand and coal particles with flow velocities that were insufficient for the flow to entrain the particles without the aid
