The location of DAM has been obtained by using AHP techniques. As a result, I have prepared the dam/reservoir suitability map. Certainly, validation is a very important part of the model. If, any other dam site is not available/ not constructed in the study area. How can we validate? Is there any method or approach?. Furthermore, Is sensitivity analysis is required for the spatial layers utilized to prepare the dam site suitability map?
I m eagerly waiting for prompt and scientific answers to overcome this difficulty?
Thanks
If no alternative dam sites are available or being built in the study region, the best option is to go to the suitable site found using AHP and survey it for Dam Site Selection Criteria.
If you do a sensitivity analysis on the weights of the spatial layers acquired using the AHP approach, it is my understanding that the weights obtained based on the expert views in the AHP method would be questioned.

Multi-Criteria Decision-Making (MCDM, also known as Multi-Criteria Decision Analysis, MCDA) refers to methods – including software – for making decisions where numerous criteria (or objectives) must be addressed concurrently in order to rank or choose between the options under consideration.
A Multi-Criteria Analysis (MCA) may be used to find and analyze policy choices by evaluating their effects, performance, impacts, and trade-offs. MCA is a systematic strategy for guiding complicated decisions based on predefined criteria and objectives.
However, Zardari et al. (2015) defined three key types of MCDM techniques, which are articulated in the form of an up-to-date classification Arslan (2017) as simple, original, and differentiated methods. Because of its simplicity and broad general application, the WSM is chosen as the best MCDM approach.
As far as the dam location validity is concerned. One cannot directly validate the Potential location. The way in which dam location is being derived doesn't require the validity.
If you want to validate the location which you are proposing, then go for Hydraulic simulations, considering approximate dam profile. See if Dam purposes gets fulfilled at the obtained site with less impact on the ecosystem.
Selection of dam sites depends on many factors such as
1. Effect on biodiversity
2. Change in ecosystem
3. Kind of dam and funds available for the project
4. Area under submergnce
5. Purpose of dam. ( irrigation , power , industries and water supply to cities )
6. Lithplogy
7. Tectonic plate
8. Gorges
And list can be big if deeply research is done.
For such issues ENVIRONMENTAL IMAPCT ASSESSMENT generally carried out before proposing the dam site.
Many international agencies gets involved for designing the dam profile and assesing the impact.
Hope this discussion helps you.
All the best
Thank you Mr.Praveen for sharing your views . The answer is really convincing.
Thanks a lot @ Mr. Praveen Rathod
