Thanks for your valuable comment,Mr.Hayder.

but in my question I want to estimate the potential sites for groundwater recharge.I already have the the map of Groundwater Potential Zones in my study area.

Dear Faez,

I suggest you install IDRISI Selva software. There is a Decision Support function  under GIS Analysis/Decision Support/WEIGHT

When you click WEIGHT, a window "WEIGHT(AHP Weight derivation" will open, then you have a tool where you can upload your files(maps) for AHP derivation, they will be compared pairwise.

Please try, your feedback is appreciated 

Dear, Canute Hyandye 

Thanks for your  comment.I ask about the suitable factors inside AHP to estimate suitable sites for recharging groundwater.

regards

You got already some nice hints! Based on my experiences in the Sahel, Atacama, Southern Tibet and the Alps I can only state that groundwater recharging is certainly very much site-dependent. I personally am rather not overly optimistic for such untertakings ...  However, give it a try.   Where is your study site?    mfb

Dear, Prof Manfred Buchroithner

Thanks alot for your valuable comment ,my study area in Kirkuk city in Iraq, and I attached the map of study area.

Regards

I just checked the climatic / precipitation conditions:

http://www.worldweatheronline.com/Kirkuk-weather-averages/At-Tamim/IQ.aspx

Based on that I can just confirm my scepticism.

You might get in touch with Dr. Al-Hameedawi, Amjed Naser Mohsin from Univ. Baghdad, one of my former PhD students. He knows the area quite well, due ti his PhD Thesis entitled "Integrative GI Technology Applied to Best-Site Selection for Industrial Areas in Erbil City, Iraq". Dresden, Technische Universität, Dissertation, 2014.

Hi Faez, 

Multi-criteria evaluation should be done by consultation with experienced experts, weighting factors is technology and site dependent. The procedures are simple; I have recently done irrigation suitability mapping using MCE you can find it in my RG (the title is Realistic Assessment of Irrigation Area Suitability). I will try to summarize you the procedures in short:

1. You have to identify the major factors which affect the rain water harvesting technology that yu have in mind. Some of the factors will be for example soil, slope, land use, you can also have a map shoving the concavity and convexity of the topography.

2. After identifying the factors the next procedure will be weighting. Out of the different weighting approaches AHP is less bias. For AHP just consult (Saaty 1977), you have to prepare a pairwise comparison matrix by using Saaty scale, then you can calculate the factors wait easily.

3. The next step is distributing the weights of factors to different levels of suitability, you can use equal interval ranging technique. For example, if one of your factor has a weight of 32 and if you have four levels of suitability; then the most suitable class will get 32, the next level of suitability will get 24, then next level of suitability will get 16 and the last one will have 8.

4. The last step is overlay analysis of reclassified factor maps.

My advice is this can be easily done by ArcGIS model builder, the model builder will give a chance to see the sensitivity of weighting.

Dear,Abeyou Wale Worqlul

Thanks so much ,I appreciate your support and help .

Try using ILWIS - has the option for SMCE  with Analytical Hierarchical Processing (AHP) option

SMCE - Spatial Multi-Criteria Evaluation

You will find good tutorials on how to use ILWIS from the ITC website and a number of tutorials on the use on AHP

Hi Faez, 

You can refer our recent publication using MCE and AHP for surface irrigation area suitability mapping. It is a similar approach:
