River ecosystem health or aquatic ecosystem health could be determined using Index of Biotic Integrity (IBI).
E-flows describe the quantity, timing, and quality of water flows required to sustain freshwater ecosystems .....
My question is, can we use P-IBI to estimate e-flows? If it can be used to pridict the impacts of a planed dam on downstream aquatic ecosystem health?
Well,
Healthy rivers are important to people Essential to human health and quality of life Support economic activity Healthy rivers need environmental flows
Regards
Environmental flows are very important for determine the water quantity which are essential for human health
Dear Ang,
You are asking an interesting question. The IBI can provide very useful monitoring information that can be used to track and evaluate the impacts of dams and their alteration of the natural flow regime. I suggest using three IBI’s together - one for algae, one for macroinvertebrates, and one for fish. That combination will provide data on impacts at three levels of the aquatic old web - it will provide a nice fingerprint of the structure and function of the ecosystem.
i can send you some currrent papers that will be helpful if you are interested. If you are interested please email me [email protected].
i hope this is helpful.
