Computational Hydraulics Group
University of Texas at Austin
The Computational Hydraulics Group (CHG) at The University of Texas at Austin
is a leading research center in the modeling of aqueous environments, including
problems related to shallow water hydrodynamics, hurricane storm surges and
groundwater pollution. The group focuses on the development and analysis of
numerical algorithms for multiphysics, multiscale flow and transport problems,
and the implementation of computational methodology in efficient, scalable,
parallel software. CHG is housed in the Institute for Computational Engineering and Sciences.
CHG's recent efforts include investigation of high-resolution algorithms based
on finite volume, discontinuous Galerkin and hybrid continuous/discontinuous
finite element methods. Dynamic
h-p adaptivity for multiscale resolution, coupled
with novel time stepping procedures, are also being developed. Methodologies are being implemented and tested on a variety of computational
platforms, from workstations to petascale parallel computers. Our parallel
simulators are scalable to tens of thousands of processors.
CHG researchers are part of the multi-university ADCIRC (Advanced Circulation)
development team. ADCIRC is a modeling framework for shallow water hydrodynamics,
with applications to hurricane storm surge modeling, coastal sustainability
and development of hurricane protection systems, and modeling of coastal environments.
In addition, we develop "next-generation" simulators with the long-range
goal of performing high-resolution, operational real-time forecasting and hindcasting.
In addition to developing numerical methods for PDEs, CHG performs research
in data assimilation and parameter estimation, using variational methods and
ensemble methods. These algorithms are also being applied to problems in groundwater
and surface water.
