The presence of water and the pattern(s) of wetland water levels are primary drivers of virtually all aspects of wetland ecology.
Understanding the water regime of wetlands is important for Australian wetlands as many go through natural, often extended, dry phases and support a suite of specially adapted organisms. Conversely wetlands that hold water permanently are also valuable ecologically as they provide refugia for flora and fauna during naturally extended dry periods or times of drought, potentially making them a source of colonisers for nearby or connected ephemeral wetlands.
Brock and Boulton describe the main features of water regime to include timing, frequency, duration, extent and depth and variability.
