Seismic wave modelling using finite difference methods
… numerical approach to model numerically seismic wave propagation, and also to ascertain if rock interfaces could be inferred from signals received at a geophone.<br/><br/>We mainly employ two different models together, namely the "Parsimonious staggered grid" and the "Box" model. So far as we are …

Seismic wave modelling using the boundary element method
… also been obtained for three-dimensional scalar waves. In addition, the three dimensional elastodynamic boundary kernels have been evolved.<br/><br/>Constant elements are normally employed to discretize the boundary. To determine the dynamical response constant elements are seen to be well …

High-resolution wave modelling in the Mediterranean Sea: Sensitivity to surface current forcing
… ανάλυσης (1/36◦) κυματικό μοντέλο τρίτης γενιάς WAVEWATCH III. Η απόδοση του μοντέλου αξιολογήθηκε μέσω συγκρίσεων με δορυφορικές και επιτόπιες παρατηρήσεις του ύψους κύματος, παρουσιάζοντας συνολικά καλή συμφωνία, ενώ παράλληλα αναδείχθηκαν οι υπάρχουσες δυσκολίες στην πειραματική επαλήθευση των …

Environmental requirements for optimal naval operational efficiency
… thesis the applicability of ocean environment modelling as a part of optimal naval operational efficiency, and thus military oceanography, is evaluated. To be able to do this, the principles of knowledge-based warfare and the ability to make rapid environmental assessments, are introduced. …

Hurricane-generated ocean wave propagation and impacts on a fringing reef in Hawai’i
… storms, had strong winds that generated large waves and impacted the islands in the summer of 2018. This study aims to investigate the ocean surface wave response to hurricane wind forcing across the ocean at a large scale and to understand the finer-scale processes of energy dissipation and …

Oceanographic considerations for the management and protection of surfing breaks
… ICZM around surfing breaks including: surfing wave parameters; surfing break components; relationship between surfer skill, surfing manoeuvre type and wave parameters; wind effects on waves; currents; geomorphic surfing break categorisation; beach-state and morphology; and offshore wave …

Sea state estimation from inertial platform data for real-time ocean wave prediction
… greatly improved spatio-temporal data. The wave glider (WG) is one such autonomous marine robot used for persistent ocean research and other maritime activities, and forms the focus of this study. The WG is a low power USV/UUV hybrid that harnesses wave energy for propulsion, and has a small …

Modelling of low- and high-frequency sea level variability and their drivers around the southern African coast
… of a methodical exploration of water level and wave dynamics in these waters. The structure of the thesis is based on the operational marine forecasting platform developed at the South African Weather Service (SAWS). As part of this thesis, I conceptualized and co-developed the operational …
