Wave Induced Mine Burial and Sediment Transport in Coastal Environment: Wave and Sediment Transport Modeling Studies
The long-term goal of this work is to develop numerical simulation techniques for predicting waveinduced sediment transport and bed evolution in the coastal zone (order 10 meter depth outside the surf zone), at horizontal scales of tens of meters or less, and the scouring/burial around objects/obstacles (mine-like), partially buried in the bottom. This research was initially motivated by the Na...
متن کاملDevelopment of a three-dimensional, regional, coupled wave, current, and sediment-transport model
We are developing a three-dimensional numerical model that implements algorithms for sediment transport and evolution of bottom morphology in the coastal-circulation model Regional Ocean Modeling System (ROMS v3.0), and provides a two-way link between ROMS and the wave model Simulating Waves in the Nearshore (SWAN) via the ModelCoupling Toolkit. The coupled model is applicable for fluvial, estu...
متن کاملSimulation of Wave-Current Interaction Using Novel, Coupled Non-Phase and Phase Resolving Wave and Current Models
The long term goals of this project are to be able to predict nearshore waves, currents, and sediment transport accurately from >20m water depth through to the shoreline. We would like to accomplish this over as large an area as possible; on the order of tens of km, and to resolve all individual waves. Time periods simulated would be of order hours to days at maximum. We would also like to be a...
متن کاملModeling of Wave-induced Sediment Transport around Obstacles1
We report on further developments of a hybrid numerical model to simulate wave-induced sediment transport. A 2D numerical wavetank (NWT) based on fully nonlinear potential flow (FNPF) equations is used to simulate fully nonlinear wave generation and propagation. A 3D Navier-Stokes model with large eddy simulation (LES) is coupled to the NWT to simulate complex turbulent flows near the ocean bot...
متن کاملA Nearshore Model to Investigate the Effects of Seagrass Bed Geometry on Wave Attenuation and Suspended Sediment Transport
The effects of seagrass bed geometry on wave attenuation and suspended sediment transport were investigated using a modified Nearshore Community Model (NearCoM). The model was enhanced to account for cohesive sediment erosion and deposition, sediment transport, combined wave and current shear stresses, and seagrass effects on drag. Expressions for seagrass drag as a function of seagrass shoot d...
