Mcmc surface wave inversion
Web9 mrt. 2024 · Inversion refers to using physical phenomena observed on the earth’s surface to infer the spatial changes of the physical structure of the underground medium. To solve the inversion problem, a number of inversion methods have evolved over the … WebContamination source identification is a crucial step in environmental remediation. The exact contaminant source locations and release histories are often unknown due to lack of records and therefore must be identified through inversion. Coupled source location and release history identification is a complex nonlinear optimization problem.
