dc.description.abstractTemporary rivers and streams that naturally cease to flow can be found on every continent. Many others that were once perennial now also have temporary flow regimes due to the effects of water extraction or changes in land-use and climate, while others that used to run dry no longer do so due to water releases and waste water discharges. The dry beds of temporary rivers are an integral part of river landscapes and have: a role as seed and egg banks for aquatic biota; a unique diversity of aquatic, amphibious and terrestrial biota; a role as dispersal corridors; as temporal ecotones linking wet and dry phases; and as sites for the storage and processing of organic matter and nutrients. They also have a societal values, such as significance in human language and culture; agricultural uses; sources of sand and gravel for building purposes; and as places for recreation. ‘Traditional’ conceptual models of riverine ecosystem structure and function do not consider the dry phase. As a consequence, these models are incomplete and are thus not fully applicable to many parts of the world where temporary rivers are common and the dry phase is significant.
