Used to map groundwater potential zones (GWP) in arid regions, identifying areas for maximum recharge by analyzing factors like soil texture, geology, and slope. It is also employed to assess water quality and identify highly polluted zones in river catchments.

The is a numeric value generated by the Simple Additive Weighting method. It represents the overall performance or suitability of an alternative. The core idea is to aggregate the weighted scores of all criteria for a given alternative into a single numerical index.

Construct a matrix where rows are alternatives and columns are criteria. Each cell contains the raw performance value of an alternative for a specific criterion. 3. Normalize the Decision Matrix

It can handle a large number of alternatives and criteria.

Studies have shown that the SAW model can provide superior performance compared to other methods like the OIF index for specific scenarios like groundwater prospect mapping . Real-World Applications of SAW

Generally indicates a better alternative (closer to the ideal solution).

The method is easy to understand and implement, making it accessible to non-experts.
