Short summary
We consider how well one can identify hydraulic conductivity that varies from place to place by using only measurements obtained at a finite number of groundwater monitoring wells. In particular, we relate how accurately features (meaning connected high- or low-conductivity regions) are identified to their size and to well spacing, and we examine which kinds of information are most valuable. When feature size exceeds 4 times the well spacing, better-than-random identification is possible.
