Multiphysics imaging or data inversion is of growing importance in many branches of
science and engineering. In geophysical sciences, there is a need for combining information …

This book places data assimilation (DA) into the broader context of inverse problems and the
theory, methods, and algorithms that are used for their solution. It strives to provide a …

A digital twin (DT) is a numerical model (in silico) of a system that runs alongside its physical
counterpart and exchanges (bidirectional) information with it. The digital twin, once suitably …

Deposition, turnover and movement of persistent organic pollutants (POP) were investigated
in the EU integrated project “AquaTerra”, which is among the first funded environmental …

Recently the concept of adjoint modeling has been introduced in shallow water acoustics for
solving inverse problems. Analytical adjoints have been derived for normal modes and for …

In accordance with the increasing industrial interests in the sea areas a two-pronged
development can be observed: an appearance of new methodologies for up-to-date and …

Knowing how the solution to time-harmonic wave scattering problems depends on medium
properties and boundary conditions is pivotal in wave-based inverse problems, eg for …

Wave-theoretic ocean acoustic propagation modeling is used to derive the sensitivity of
pressure, and complex demodulated amplitude and phase, at a receiver to the sound speed …

The integrated project “AquaTerra” with the full title “integrated modeling of the river–
sediment–soil–groundwater system; advanced tools for the management of catchment areas …

The interpretation of wave scattering data has led, and continues to lead, to a wide range of
scientific discoveries and practical engineering applications in domains as varied as …
