Discontinuous Galerkin Methods for Modeling Hurricane Storm Surge
Abstract Storm surge due to hurricanes and tropical storms can result in significant loss of life, property damage, and long-term damage to coastal ecosystems and landscapes. Computer modeling ofExpand
A Performance Comparison of Continuous and Discontinuous Finite Element Shallow Water Models
In a series of numerical tests, it is demonstrated that the DG SWE model is generally more efficient than the CG model in terms of achieving a specified error level for a given computational cost and on large-scale parallel machines because of the inherently local structure of the method. Expand
A River Discharge Model for Coastal Taiwan during Typhoon Morakot
Abstract : In the coastal waters of Taiwan, freshwater discharge from rivers can be an important source of uncertainty in regional ocean simulations. This effect becomes especially acute duringExpand
A future for intelligent autonomous ocean observing systems
Ocean scientists have dreamed of and recently started to realize an ocean observing revolution with autonomous observing platforms and sensors. Critical questions to be answered by such autonomousExpand

Adaptive hierarchic transformations for dynamically p-enriched slope-limiting over discontinuous Galerkin systems of generalized equations
A family of generalized slope limiters in two dimensions for Runge-Kutta discontinuous Galerkin (RKDG) solutions of advection-diffusion systems are studied and a series of coupled p-enrichment schemes are introduced. Expand
Time-evolving acoustic propagation modeling in a complex ocean environment
During naval operations, sonar performance estimates often need to be computed in-situ with limited environmental information. This calls for the use of fast acoustic propagation models. Many navalExpand
Time-optimal path planning: Real-time sea exercises
We report the results of sea exercises that demonstrate the real-time capabilities of our fundamental time-optimal path planning theory and software with real ocean vehicles. The exercises wereExpand
