Cretaceous times onwards led to the opening of the Tasman Sea, causing the reversal and beheading of the original northwest-flowingstreams and the formation of the Great Escarpment. The evolution of the Clarence River does not fit into most conventional
The influence of microform bed roughness elements on flow and sediment transport in gravel bed rivers : a reply
Carrying capacity ; Flood ; Flow ; Fluvial hydrology ; Fluvial processes ; River bed ; Sediment transport ; Turbulence
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.
Modelling floodplain flows using a two-dimensional finite element model

A prototype two-dimensional finite element flow model for depth-averaged free surface flows is developed for floodplain environments. Preliminary model results indicate that this modelling approach can be used to identify dynamic variations
in the flow field parameters over length scales of the order of 10-100 m. Potentially, such data have the ability to permit detailed analysis of short-term floodplain sedimentary dynamics.
Follow the flowers : the itinerant bee-keepers of China
Although bee keeping and honey production are not long traditions in China, many people from four provinces now move with their hives to find honey sources in flowering plants and to pollinate crops. Two thirds of the honey in China is exported
The influence of microform bed roughness elements on flow and sediment transport in gravel bed rivers : comment on a paper by Marwan A. Hassan and Ian Reid
The purpose of this discussion is two-fold : 1) to provide a further demonstration of the importance of treating the bedform-flow resistance-sediment transport system in a gravel-bed river as a dynamic interaction, as has been the case for many
This paper presents a discussion of the evidence from the Lairig Ghru in the Cairngorm Mountains and explores the relationships between snow avalanche and debris flow activity. Although isolated examples of snow avalanche landforms have now been
Climatic change and debris flow activity in high-mountain areas. A case study in the Swiss Alps

In the course of the heavy thunderstorms in summer 1987, countless debris flows occurred in different areas of the Swiss Alps. This situation provided a unique possibility for investigating several aspects of debris flows which developed under
