Resolution analysis of tomographic slug test head data: Two‐dimensional radial case

摘要: Hydraulic tomography inverse problems, which are solved to estimate aquifer hydraulic properties between wells, known be ill-conditioned and a priori information is often added regularize numerical inversion of head data. Because both data have effects on the inversed solution, assessing meaningful contained in alone required ensure comprehensive interpretation solutions, whether they regularized or not. This study thus aims assess amount tomographic slug tests resolve heterogeneity Kh, Kv/Kh, Ss. Therefore, resolution analysis based truncated singular value decomposition sensitivity matrix with noise level representative field measurements applied using synthetic reflecting littoral aquifer. As an approximation behavior real system, experiments associated matrices generated radial flow model accounting for wellbore storage simulate plane encompassing stressed well observation well. Although fine-scale heterogeneities limited by diffusive nature groundwater equations, holds potential uniquely coarse-scale Ss, as inscribed matrix. implies that can provide key anisotropy, but must supplied obtain finer details.
