  • Channel units in small, high gradient streams on Vancouver Island, British Columbia
  • The aim of this paper is to present a classification and descriptions of channel units in small, very high gradient mountain channels and to discuss the efficacy of the classification criteria : bedrock cascades, boulder cascades, rapids, chutes

  • ; and to analyse their relation with hydrological and sedimentological processes. This article presents the first digital object-oriented dataset of islands, wetlands and channels with full spatial coverage of the Okavango Delta. Islands were divided into discrete
  • classes and the occurrence, size and density of island types was analysed in relation to physiographic regions and channels in various stages of development.
  • The aims of this study were : to classify the continuum of wet and dry areas into object-oriented classes of islands and wetland regions; to estimate the qualitative and quantitative distributions of these components throughout the Okavango wetland

  • Anastomosis and the continuum of channel pattern
  • Australia ; Canada ; Channel geometry ; Classification ; Concept ; Flood ; Floodplain ; Fluvial processes ; Meander ; River bed
  • Anastomosing rivers are characterized by multiple channels separated by islands excised from the floodplain. Their status relative to the continuum concept of channel pattern is assessed with channel pattern defined in terms of three variables: flow
  • strentgh, bank erodibility and relative sediment supply. Anastomosis may in certain cases represent a transitional form of channel pattern but there is no denying the longevity of some anastomosing systems.

  • A major dredging programme to deepen the shipping channels at the Port of Tauranga has seen some 5 million m3 of mainly sandy sediment dredged from the shipping channels and dumped on the adjacent inner shelf. An Environmental Impact Assessment has
  • Channel geometry ; Floodplain ; Fluvial processes ; Ireland ; Island ; River bed ; Stream flow ; Tree ; Vegetation
  • This paper presents data on the flood response of channels in one of the last wooded, semi-natural anastomosing systems in Europe. The Gearagh, Ireland, is characterized by hundreds of small islands separated by interconnected channels of low slope
  • . Islands are relatively stable and wooded, with evidence of division by channel erosion and growth by in-channel sedimentation. Biotic components such as debris dams, tree root masses and tree-throw pits play a key role in the partitioning of flow
  • , and cause variations in channel velocities and the overbank velocity distribution. The implications for channel pattern maintenance are briefly discussed.

  • An inventory of 846 mass movements, mainly landslides, in 2 alpine regions of southwest New Zealand was created to explore the geomorphic impacts of slope-failure processes on river channels and valley floors. A nominal classification system
  • is introduced for characterizing : the physical contact nature between landslides and river channels; and the resulting geomorphic consequences for drainage. Dominant persistent geomorphic imprints of bedrock landslides include channel occlusions and landslide

  • The geomorphic work accomplished during an extreme storm event by 3 primary tributaries in the western Manawatu river catchment (New Zealand) is assessed using sequential aerial photographs. Areas of floodplain and channel erosion were quantified
  • as a measure of the work accomplished during floods triggered by a 150-year storm in February 2004. The contrasting amount of geomorphic work between these tributaries relates to valley floor and channel configurations, which prime discrete reaches

  • Come a nasty gale : the response to Hurricane Hugo on the island of Montserrat, West Indies
  • On September 17, 1989, a hurricane devastated this tiny island : trees were defoliated, floods repositioned river channels, and most dwellings were damaged. But the relief effort also reinforced community solidarity.―(DWG)
