  • Estuarine and Coastal Research Unit, ECRU (CSIR, National Research Institute for Oceanology, 1981-04)
    The Gamtoos has the fourth largest catchment of all the Cape rivers, with an area of 34 438 km2 which extends right up into the Great Karoo. Two large tributaries drain the eastern extremity of the Nuweveld Mountain range ...
  • Estuarine and Coastal Research Unit, ERCU (CSIR, National Research Institute for Oceanology, 1981-04)
    The Spoeg has a relatively small catchment area and probably only flows into the sea at times of extreme flooding. As the dune covered catchment readily absorbs the run-off, the mouth does not appear to be subject to heavy ...
  • Estuarine and Coastal Research Unit, ECRU (CSIR, National Research Institute for Oceanology, 1981-04)
    The estuary falls within a strict security area of the Koingnaas mining concession of De Beers Consolidated Diamond Mines. Due to the active mining operations in the immediate vicinity of the estuary, security clearance ...
  • Estuarine and Coastal Research Unit, ECRU (CSIR, National Research Institute for Oceanology, 1981-04)
    This report entails available historical information on Buffels estuary and abiotic and biotic characteristics found in the estuary are presented. Although the Buffels River has a relatively large catchment compared with ...
  • Estuarine and Coastal Research Unit, RCRU (CSIR, National Research Institute for Oceanology, 1981-06)
    The nature of the Bitter surface sediments in the mouth region suggest that the river flows intermittently but probably only for short periods. This is to be expected from the nature of the rainfall and the small size of ...
  • Estuarine and Coastal Research Unit, ECRU (CSIR, National Research Institute for Oceanology, 1981-06)
    The state of knowledge of the Groen is poor. The area, being remote, has received little attention in the past and the bulk of information in this report originates from the Estuarine and Coastal Research Unit (ECRU) survey. ...
  • Estuarine and Coastal Research Unit, ECRU (CSIR, National Research Institute for Oceanology, 1981-06)
    The Holgat is not an estuary in the true sense, due to a combination of factors. Although the catchment has an area of 1500 km2, the Holgat last flowed in 1925. The main reason for this appears to be the low rainfall in ...
  • Council for Scientific and Industrial Research, CSIR; National Research Institute for Oceanology, NRIO; Eustuarine and Coastal Research Unit, ECRU (CSIR, Eustuarine and Coastal Research Unit, 1982)
    This record is an overview of the Green Series Reports produced by the Estuarine and Coastal Research Unit (ECRU) of the Division of Earth, Marine and Atmosphere Science and Technology at the Council for Scientific and ...
  • Estuarine and Coastal Research Unit, ECRU (CSIR, National Research Institute for Oceanology, 1982-01)
    This report provides historical overview on river catchment, ecology, biotic and abiotic characteristics and available information on the Rooiels estuary. The Rooiels estuary is a small but ecologically healthy system on ...
  • Estuarine and Coastal Research Unit, ECRU (CSIR, National Research Institute for Oceanology, 1982-02)
    This report provides historical overview on river catchment, ecology, biotic and abiotic characteristics and available information on the Uilkraals estuary. The Uilkraals has a relatively small Table Mountain Sandstone ...
  • Heinecken, TJE; Bickerton, IB; Morant, PD (CSIR, National Research Institute for Oceanology, 1982-06)
    This report is a synthesis of all available information on five of the smaller rivers discharging in to False bay combined as a single volume. The rivers dealt with are the Buffels (Wes), Elsies, Sir Lowry' Pass, Steenbras ...
  • Estuarine and Coastal Research Unit, ECRU (CSIR, National Research Institute for Oceanology, 1982-06)
    A detailed account of the history of the Kowie estuary and the attempts to develop a harbour at the mouth of the river are given in the “Basket Work Harbour”. (Turpin, 1964). As far as could be ascertained, the river has ...
  • Estuarine and Coastal Research Unit, ECRU (National Research Institute for Oceanology, CSIR, 1982-06)
    This report provides an overview of the Hartenbos estuary of the Cape Coast dealing with aspects such as climate, geology, soils, catchments, run-off, vegetations, oceanography and estuaries. In this report available ...
  • Estuarine and Coastal Research Unit (CSIR, National Research Institute for Oceanology, 1982-09)
    Various charts and title deeds give the name of the river as the Zilvermyn rivier, Silver Mijn Stream or Silvermynrivier. The name Silvermine apparently originates from attempts in the 1680s to mine silver in the valley ...
  • Estuarine and Coastal Research Unit, ECRU (CSIR, National Research Institute for Oceanology, 1982-09)
    In this report an attempt is made to synthesis available information on the Botriviervlei and Kleimond estuary. The name Bot River is probably a direct reference to the slow flowing nature of the river and derived from ...
  • Estuarine and Coastal Research Unit, ECRU (National Research Institute for Oceanology, CSIR, 1982-10)
    This report provides information about Lourens River. The Lourens River was known in the late 17th century as the Tweederivier, since it was the second river crossed on the journey from the Cape Peninsula to the Hottentots ...

    This report is one of a series on Cape Estuaries being published under the general title "The Estuaries of the Cape, Part 2". The report provides information on sand estuary: historical background, abiotic and biotic ...
  • Bickerton, IB (CSIR, National Research Institute for Oceanology, 1982-12)
    This report provides historical information on the Zeekoevlei. The Zeekoe canal at present constitutes a public health hazard, particularly where it passes under the Baden Powell Drive bridge and flows across the beach ...
