Currently a model developed in South Africa - not sure how applicable it will be in your situation.

Wynand  Thank you so  much for the response. Do you have a link to the literature for that work?? It would be a great help.

Thank you,

Regards

There is some reports available from the Water Research Commission - www.wrc.org.za

You can do searches in the "knowledge hub" and order some of the info. 

Hi Pranita!

This doesn't directly relate to wetlands, but years ago, we constructed a compund index of water quality, catchment geomorphology and biota. I attached the paper.

Alan Herlehy's group has also published a fair about this.

Hope that helps!
