The ecological limits of hydrologic alteration (ELOHA): a new framework for developing regional environmental flow standards
SUMMARY 1. The flow regime is a primary determinant of the structure and function of aquatic and riparian ecosystems for streams and rivers. Hydrologic alteration has impaired riverine ecosystems onExpand
Simple Words and Fuzzy Zones: Early Directions for Temporary River Research in South Africa
/ Although a large proportion of South Africa's rivers are nonperennial, ecological research into these systems has only recently been initiated. Consequently, we have little verified informationExpand
Inland Waters of Southern Africa: An Ecological Perspective
I. The Subcontinent.- 1. Introduction.- 2. The geomorphology of southern Africa.- 3. The climate.- 4. The regional limnology of southern Africa.- 4.1 Surface waters of the subtropical coastalExpand
The geomorphology of southern Africa
Since the separation of Africa from Gondwanaland (Fig. 2.1) the coastal rimland of the southern subcontinent has been subject to successive elevations and subsequent coastal abrasion. This coupledExpand
Macroinvertebrate functional feeding groups in the middle and lower reaches of the Buffalo River, eastern Cape, South Africa. I. Dietary variability
SUMMARY 1  The question of whether the diets of twelve abundant macroinvertebrate taxa from the middle and lower reaches of the Buffalo River (eastern Cape, South Africa) were too variable toExpand
Development of an operating rule model to simulate time series of reservoir releases for instream flow requirements
The output from many of the instream flow assessment workshops, currently being held in South Africa whenever a major water resource development is proposed, is a matrix of monthly flow rates thatExpand
The effects of impoundment on the physicochemistry of two contrasting southern african river systems
The downstream effects of six impoundments on their respective physicochemical conditions over two years are compared for two contrasting for two contrasting rivers. The impoundments studied includedExpand
THE DEVELOPMENT OF A GEOMORPHOLOGICAL CLASSIFICATION SYSTEM FOR THE LONGITUDINAL ZONATION OF SOUTH AFRICAN RIVERS
ABSTRACT The recognition of the Reserve by the new South African Water Law poses new challenges for river scientists. The ecological water requirement or environmental flow is recognised by that partExpand
