Instrumentation to Measure Bottom Roughness from GEOPROBE Tripods.

摘要

The long-term goal of our research is to improve our ability to model sediment transport and accumulation in coastal oceans. In particular, we hope to develop regional-scale models (~10s of kilometers) with predictive capability over time scales of decades. Such models are useful for a wide range of engineering, environmental, and tactical Naval applications. Field observations and measurements of sedimentary processes are a key component of our research, because careful quantitative data are needed to improve parameterizations of sedimentary processes and to test existing models. Measurement of bottom topography is crucial for interpretation of boundary layer processes because bottom roughness directly affects near-bottom flow, and sedimentary processes can alter bottom morphology.
