CD44A:
Connecting "Roughness" and "Bathymetry": Resolving the Often Unresolved Interactions Between Time-Varying Flow and Topography II Posters


Session ID#: 28294

Session Description:
Topography in the ocean varies continuously over a wide range of length scales, from scales typically considered “roughness” to those considered “bathymetry”. Flow is also driven over topography at a range of time scales by processes such as surface and internal waves, tides, and steady currents. Interaction of flow with topography causes persistent spatial patterns in pressure, currents, and turbulence. In ocean circulation models where the domain is discretized into a finite resolution grid, some of these processes are resolved and others are not. The goal of this session is to bring together the growing number of people who are investigating flow-topography interactions at a range of spatial and temporal scales. We particularly encourage studies in shallow coastal systems such as the inner shelf and nearshore, coral reefs, and vegetation canopies. Field observations, laboratory measurements, numerical modeling, and theoretical studies that contribute to understanding this problem are all encouraged. We hope to inspire discussion about the physics of interactions between time-varying flow and topography, ways these processes are currently parameterized, and how they might be better represented.
