Assessing the health of Ephemeral Rivers

Assessing the geomorphic and hydrologic aspects of ephemeral rivers is an important part of measuring their health. Ideally, a few accurate, repeatable, rapid measurements would describe their condition and allow changes to be assessed over time. Researchers and managers have developed a large number (hundreds) of hydrologic and geomorphologic indicators which are summarised in this review. Often a suite of indicators, developed by a management agency, will be applied to streams in a (more)...

Assessing the health of Ephemeral Rivers

This project aims to identify the most appropriate methods to assess health in these streams but is also intended to support further development so that ephemeral streams, in other areas of Australia, can also be assessed. The project is being undertaken by the Cooperative Research Centres for Catchment Hydrology and Catchment Ecology. These CRCs are consortiums of the Universities and industry partners with researchers based at University of Adelaide, Griffith University, University of Canberra, (more)...

Environmental Water Allocation required to sustain macroinvertebrate species in ephemeral streams

Project Objectives: To determine the key drought refuges used by macroinvertebrate species in intermittently-flowing streams and determine the level of threat to each refuge posed by prolonged drying and unpredictable flow regimes To determine the role played by different types of drought refuge in restocking macroinvertebrate populations in rivers and therefore the consequences for river communities of loss of each type of drought refuge. To determine the (more)...
