well... you tried using a simulator of water quality ? sure you will need a lor of physical - chemical properties of the water, but it's an easy way to analyze global situations.

Different sources you mentioned can generate different types of impacts to wetlands, and therefore it is advisable to analyze each stream separately.

Thanks,

Dear Anand,

It seems to me that you are trying to do job for the Institute. I had once the same idea with National Parks. But making of interactive maps needs professional in ArcView 8.x and 9.x, to date even 10.x. Now its name is ArcGIS Desktop. Simply say you should cooperate with specialists in GIS technologies. Enter this forum in RG !

I agree with José that you need a lot of different indices of chemical, physical and biological nature to select the most important factors to forecast changes and further possibilities to work with wetlands in rural areas. I saw perfect examples of integration the wetlands into the city landscape in Malmo (Sweden),

Dear Arnaud, 

 following the old advises giving by the researchers below, i want to advise you to segragate data according to the water facilities. After that,  use PCA to analyse statistically with spss or xlstat software 

Use also Arcgis to illustrate and present the thematic map

Thank you Jean Ghislain sir,

Hope you doing well.

I have no clue about thematic map. how to prepare it. any free download software or something more available here to make it.

please suggest me.

it would be easy to me.

i welcome your suggestions.

Regards

Hi Arnaud,

I agree with several on the forum that to help represent your points on a map and show relation to one another the best software to use would be ArcMap 10. However, it is not a free software. I don't know if it is a possibility for you to link of with another individual from a university or organization for a cross publication that might want to help with the ArcMap component.

For the wetland analysis. Obviously if you have the ability to measure the chemical components of the water that would be the best way to identify sewage contaminants in the water. However if that is not a feasible option there are other ways to measure high levels of nutrients. I would imagine in Dubai you will be dealing with different species than I do here in CO but we have species indicators for fecal contaminants (such as black fly larva). I agree with Jean regarding your statistics. Do you have a software program to help you with your statistics?

Thank you Corinna Photos sir.
