Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that the radius of influence around a groundwater pump well can be calculated mathematically?

Yes. Mathematical models and analytical solutions are well established in hydrogeology to calculate the radius of influence, drawdowns, and flow characteristics around a groundwater pumping well.
