THE DUAL NATURE OF HYDROPEAKING RIVERS: IS ECOPEAKING POSSIBLE?

摘要: Philosophically, the natural flow regime concept is tremendously appealing; however, its application can be challenging for many biologists without expertise or resources to handle such approaches on their own. This particularly true hydropeaking rivers, where incorporating sometimes challenging. Additional challenges include our limited understanding of how individual components relate geomorphic and ecological processes. Supplementary environmental that rivers are ecologically two different in one: low high peaking flow. Taxa require a narrow range water velocities cannot withstand rapid changes discharge would likely eliminated competitively disadvantaged under harsh conditions. As peak flows diverge, become increasingly ecologically, there will fewer taxa abiotic variability. Deviations from may result new constraints certain fishes invertebrates, but this does not necessarily mean loss productive fish habitat. Viewing as one risks associated with ratios serve more practical useful perspective towards maintaining altered yet while representing step improving management river ecosystems. © Her Majesty Queen Right Canada 2013.
