Second order adjoint sensitivity analysis in variational data assimilation for tsunami models

15 Mar 2020 Kevlahan N. K. -R. Khan R. A.

We mathematically derive the sensitivity of data assimilation results for tsunami modelling, to perturbations in the observation operator. We consider results of variational data assimilation schemes on the one dimensional shallow water equations for (i) initial condition reconstruction, and (ii) bathymetry detection as presented in Kevlahan et al. (2019, 2020)... (read more)
