When is a River not a River ? Consideration of the legal definition of a river for geomorphologists practising in New South Wales, Australia
  • When is a River not a River ? Consideration of the legal definition of a river for geomorphologists practising in New South Wales, Australia
  • Australia ; Concept ; Definition ; Environmental management ; Geomorphology ; Legislation ; New South Wales ; Perception ; River bed ; Stream ; Water resources
  • This paper examines why the definition of a river is an important and ongoing management issue, and outlines the development of legal definitions of river. Finally, the role of fluvial geomorphology is discussed with respect to the definition
  • of a river and its channel. This analysis will reveal whether the existing legislative framework adequately reflects the physical realities of rivers and watercourses so as to facilitate their conservation.

  • Sedimentatieverschijnselen nabij een rivier stuw op de Markrivier Sedimentation phenomena near a river dam on the river Mark
  • To alter the natural river behaviour, many regulation projects have been carried out on various river systems. However, until now very few studies on the reactions of the rivers to the imposed regulating systems have been undertaken. - (Author).
Anabranched rivers
  • Anabranched rivers
  • Channel geometry ; China ; Fluvial dynamics ; Fluvial processes ; Meander ; Model ; River bed ; Statistics ; Stream ; Stream flow
  • Since the anabranched river pattern is the most typical one in the middle and lower reaches of the Yangtze River (Changjiang) as well as in many other rivers in China, a systematic study on the formation cause of the anabranched river pattern has
  • been made in recent years, including field observations, modeling experiments in four river models under different boundary conditions, the analyses of river pattern formation and transformation etc. In this paper, some of the detailed results obtained

Geometric properties of river cross sections and associated hydrodynamic implications in Wuhan-Jiujiang river reach, the Yangtze River
  • Geometric properties of river cross sections and associated hydrodynamic implications in Wuhan-Jiujiang river reach, the Yangtze River
  • Based on measured hydrological data by using ship-mounted Acoustic Doppler Current Profiler (ADCP) instrument, the AA. analyzed shapes of river cross sections of the middle Yangtze River basin (mainly focusing on Makou and Tianjiazhen river reach
  • ). The hydrologic data of 36 river cross sections have been successfully obtained. In this paper, the AA. try to characterize the hydrodynamic properties of river knots, associated backwater effects and their implications for flood mitigation in the middle and lower
  • Yangtze River basin are also discussed.

The evolution pattern on the Yellow River delta system
  • The evolution pattern on the Yellow River delta system
  • The Yellow River delta is a fluvial action dominating, highly constructive sedimentary system. The evolution pattern of the delta is closely related to the hydrologic features and the suspended sediment load of the Yellow River as well as the river

European rivers: first results
  • European rivers: first results
  • 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).

Persistent and ancient rivers. Some australian examples
  • Persistent and ancient rivers. Some australian examples
  • Australia ; Cenozoic ; Drainage network ; Geochronology ; Palaeogeography ; Palaeohydrology ; Palaeosurface ; River bed ; Stream
  • Rivers are positive feedback systems and, once established and dominant, tend to maintain and enhance that dominance. Thus, major rivers ought to persist. Rivers, some 60 m.y. old (Eocene), that are extant and have been continuously active since
  • initiation have been identified in Australia. Other rivers of equal or even greater antiquity, but with slightly chekered chronologies, also persist in the landscape, as do the ghosts of others. River of similar antiquity occur in other Gondwana landscapes.

  • The types of river reaches for the major Hungarian rivers/lower reaches: alluvial fan accumulation| meandering and downcutting| meandering and infilling| equilibrium or final state| upper reaches: downcutting/ are demonstrated on map. Grain size
  • distribution of channel fill and load are studied. Most of the rivers belong to the downcutting type which is promoted by river regulations increasing slope. (DLO).

  • Conceptual model ; Decision making process ; Ecology ; England and Wales ; Environmental management ; Gravel ; Model ; Rehabilitation ; River bed ; Stream ; United Kingdom ; Watershed
  • This paper is concerned with development and application of a conceptual model of the river restoration process and, through a specific case study, a demonstration of the challenges that arise when combining ecological and geomorphological
  • principles with social and economic issues. This, it demonstrates the difference between the ideal goals of river restoration and the practical determinants of the nature of a river restoration that derive from individual and community goals.
