Interactions of Waves and River Plume and their Effects on Sediment Transport at River Mouth (RIVET I)

چکیده
The interaction between the hydrodynamics and complex bathymetry can produce highly heterogeneous and locally energetic flows, e.g., in a tidal inlet dominated by tidal flow and wave-current interaction. Consequently, the morphological evolution around such tidal inlet also becomes very dynamic. These two factors cause concerns over navigation safety especially in areas where routine surveys are not possible. Through significantly improved remote sensing technology, data on the surface flow features and limited information on the bottom bathymetry can be obtained. However, a complete prediction on the detailed hydrodynamics, bottom bathymetry and morphodynamics still relies on numerical modeling. On the other hand, it is also unclear if existing wave-averaged coastal modeling systems are sufficiently robust to provide the critical link (interpolation) between the remote-sensing data and the ground-truth data. The main challenges appear to be due to several key intra-wave and bottom boundary layer processes that are not directly resolved in typical coastal modeling systems. For example, it is well-known that in numerical modeling of inlet hydrodynamics, the results are sensitive to parameterization of bottom friction, which is a complicated function of flow depth, bedform and wave-current interactions.

Interactions of Waves, Tidal Currents and Riverine Outflow and their Effects on Sediment Transport (RIVET II)
Studying the mixing of riverine freshwater and coastal water is the fundamental step to further understand the balance of a coastal/estuarine ecosystem (e.g., Hickey et al. 2010), seabed properties, sediment budgets (Gelfenbaum & Kaminsky 2010), and the sustainable management of the fluvial-estuary habitat (e.g., damming, dredging). The nearfield of a river plume represents an energetic environ...
متن کاملBackwater and river plume controls on scour upstream of river mouths: Implications for fluvio-deltaic morphodynamics
[1] Sediment flux from rivers to oceans is the fundamental driver of fluvio-deltaic morphodynamics and continental margin sedimentation, yet sediment transport across the river-to-marine boundary is poorly understood. Coastal rivers typically are affected by backwater, a zone of spatially decelerating flow that is transitional between normal flow upstream and the offshore river plume. Flow dece...
متن کاملIn-situ and Land-Based Remote Sensing of River Inlets and Their Interaction with Coastal Waters
An observational program applying a broad suite of in-situ and boat-based remote sensing tools to the New River inlet and its interaction with the ocean was implemented during the RIVET I experiment. Of particular interest was the flow of the river through and within the inlet; wave breaking within the inlet as a result of shoaling and wave-current interactions; and the fate, dilution, and tran...
متن کاملEstimation of Sediment Transport Rate of Karun River (Iran)
Several types of sediment transport equations have been developed for estimation of the river sediment materials during the past decades. The estimated sediment from these equations is very different, especially when they applied for a specific river. Therefore, choice of an equation for estimation of the river sediment load is not an easy task. In this study 10 important sediment transport equ...
