Hey Ráĥmá,

Yes! There's a great study that might help guide what you're looking for. It’s called: “Sensitivity Analysis of DRASTIC Model in Vulnerability Assessment of Shahrood Alluvial Aquifer” Here’s the link to the article: 👉 https://www.wwjournal.ir/article_17357_en.html?lang=en

They use two well-known methods:

• Map Removal Sensitivity
• Single Parameter Sensitivity

I've also created a simple Excel template based on that paper, where you can input your DRASTIC parameters and weights, and it will calculate sensitivity scores automatically.
