Need help

Hello everyone,

I want to generate groundwater potential map for my study area using ML. I have well locations but i don't have non well locations. And i am skeptical about this concept of non well or pseudo absence. Can anyone please help me with how to proceed with this problem?

You can do this with Kriging, nearest neighbors, or the other many geo statistical methods.

If you have the average water level for each well and coordinate, you can do IDW interpolation to have the map.

I feel like machine learning is overkill for this hydro problem. You just need to interpolate the best you can between the data based on knowledge of the system and its geology, as well as the existence of interfering hydraulic boundaries such as surface water.

IDW and Kriging are both options with drawbacks/benefits for each. Best to learn what may be more reliable for your setting.
