All of them are defined through partial differential equations, which need to be restricted with respect to scattered measurements of the total hydraulic head H, or electrical potential φ, or tracer concentration c obtained from a series of tests. Here, we will briefly describe a generic solution approach applicable to all the four inverse problems on the basis of geostatistics. More details can be found in Ref. [25]. Let χ be a generic symbol representing a primary variable to be estimated, based on a priori knowledge of χi∗ at 1 ≤ i ≤ nχ locations and measurements of a secondary variable v∗j at 1 ≤ j ≤ nv locations.

Similar adaptive mesh refinement is also desirable in hydraulic tomography when the hydraulic conductivity K(x) and/or the specific storage Ss (x) are locally rapid varying functions of x. Moreover, higher resolution around the location of the source term Q is often necessary and can be achieved by adaptive mesh refinement. 2 An example showing the necessity of using adaptively refined finite element meshes in connection with tracer tomography. 3 Parallel Subsurface Imaging with Adaptivity 39 make domain decomposition a nontrivial task in connection with parallel computing.
