  1. Pedogeomorphic aspects of the Roodepoort area, Transvaal: Soil depth-slope relationships

    Pedogeomorphic aspects of the Roodepoort area, Transvaal: Soil depth-slope relationships

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Fifty hillslope profiles with associated soils in the Roodepoort area, Transvaal, were examined to determine the relationships between soil depth and hillslope characteristics. A meso-scale approach was adopted which implied the relationship between three soil depth phases and the hillslope...
  2. AN ASSESSMENT OF THE POTENTIAL IMPACT OF ALIEN INVASIVE VEGETATION ON THE GEOMORPHOLOGY OF RIVER CHANNELS IN SOUTH AFRICA

    AN ASSESSMENT OF THE POTENTIAL IMPACT OF ALIEN INVASIVE VEGETATION ON THE GEOMORPHOLOGY OF RIVER CHANNELS IN SOUTH AFRICA

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    Invasion of the riparian zone by alien vegetation is recognised as a serious problem in many areas of South Africa. Vegetation is a dynamic component of river channels. It is an important control variable affecting channel form whereas the flow...
  3. A GEOMORPHOLOGICAL APPROACH TO THE IDENTIFICATION AND CLASSIFICATION OF INSTREAM FLOW ENVIRONMENTS

    A GEOMORPHOLOGICAL APPROACH TO THE IDENTIFICATION AND CLASSIFICATION OF INSTREAM FLOW ENVIRONMENTS

    Item type: Journal Article • Journal: Southern African Journal of Aquatic Sciences
    This paper highlights the considerable confusion that exists within the ecological literature concerning the classification of the lotic (flowing water) environments. A large number of ill defined terms has been introduced by various authors; these often relate to better defined...
  4. The application of a hydraulic biotope matrix to the assessment of available habitat: Potential application to IFRs and river health monitoring

    The application of a hydraulic biotope matrix to the assessment of available habitat: Potential application to IFRs and river health monitoring

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    In an attempt to meet the requirement of the new South African Water law a number of initiatives are under way to determine the flow requirements for our rivers. An essential component of this initiative is the determination of the...
  5. Towards a classification of Tanzanian rivers: a bioassessment and ecological management tool. A case study of the Pangani, Rufiji and Wami–Ruvu river basins

    Towards a classification of Tanzanian rivers: a bioassessment and ecological management tool. A case study of the Pangani, Rufiji and Wami–Ruvu river basins

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    River classification is important for reporting ecological status and for the general ecological management of river systems by partitioning natural variability. A priori river classification by abiotic variables and validation of classifications obtained using aquatic macroinvertebrates from reference sites for...
  6. Bathymetry, substrate and fishing areas of Southeast Atlantic high-seas seamounts

    Bathymetry, substrate and fishing areas of Southeast Atlantic high-seas seamounts

    Item type: Journal Article • Journal: African Journal of Marine Science
    Most of the Southeast Atlantic Ocean is abyssal, and global bathymetries suggest that only ∼3.2% of the areas beyond national jurisdiction (ABNJ; also known as the high seas, as defined in the United Nations Convention on the Law of the...
