Convergence analysis of a variational data assimilation scheme for bathymetry detection from surface wave observations
N. K. -R. Kevlahan, R. A. Khan
Accurate mapping of ocean bathymetry is a multi-faceted process, needed for safe and efficient navigation on shipping routes and for predicting tsunami waves. Currently available b…

On the convergence of data assimilation for the one-dimensional shallow water equations with sparse observations
N. K. -R. Kevlahan, R. Khan, B. Protas
The shallow water equations (SWE) are a widely used model for the propagation of surface waves on the oceans. We consider the problem of optimally determining the initial condition…

Compressive sampling for energy spectrum estimation of turbulent flows
Gudmundur F. Adalsteinsson, Nicholas K. -R. Kevlahan
Recent results from compressive sampling (CS) have demonstrated that accurate reconstruction of sparse signals often requires far fewer samples than suggested by the classical Nyqu…
