Basic flow field in a tidal basin

نویسنده

  • Sergio Fagherazzi
چکیده

[1] A simplified model for tidal flow in a basin is presented. The model is based on the assumption of a flat water surface oscillating synchronously in the tidal basin. Under this hypothesis the depth-averaged continuity equation becomes a Poisson equation that can be easily resolved at each instant of the tidal cycle. This formulation, which is particularly valid for small, deep basins, provides a simplified solution of the depth-integrated shallow water equations and suggests a possible approach to model long-term morphodynamic evolution of tidal basins. The model is tested in San Diego Bay, California, and the results are briefly discussed.

Tidal flow field in a small basin

[1] The tidal flow field in a basin of small dimensions with respect to the tidal wavelength is calculated. Under these conditions, the tide becomes a standing wave oscillating synchronously (with a flat water surface) over the whole basin. The shallow water equations can thus be strongly simplified, expressing the discharge vector field in terms of a potential function and a stream function. T...

Investigating the effect of Inlet and Outlet location on Flow field and Sedimentation pattern of a rectangular settling basin using CCHE2D

Water obtained from any source may contain impurities induced by erosion, dissolved minerals, dissolved gases and material produced from organic matter decomposing. If the amount of these substances exceed a certain limit, not only the water would not be potable, but the water containing the material will not be suitable to be used in most applications, or at least before treatment cannot be ap...

تاثیر جزر ومد بر رفتار بلند مدت مورفولوژی در حوضچه‌های وسیع جزر و مدی

Tidal basins are described by major features such as tidal flat, tidal channel, intertidal area, and tidal prism, which have been formulated by some empirical relations based on field observations. Although empirical relations explain some morphological patterns, those are not applicable to all conditions. Due to the lack of observations for different areas and under different geophysical condi...

Derivation of Geodesic Flow Fields and Spectrum in Digital Topographic Basins

We present a framework to characterize terrestrial functions—surficial and bottom topographic regions that are represented, respectively, as raster digital elevation models DEMs and digital bathymetric models DBMs —through analysis of flow fields that are simulated via geodesic morphology. Characterization of such functions is done via a new descriptor. Computation of this new descriptor involv...

On the Formation of Radial Tidal Current off the Central Jiangsu Coast

In the South Yellow Sea off the Jiangsu coast, there exists a special type of sand bodies, which are known as radial sand ridge field (RSRF). One of the characteristics of this area is the distinctive radial tidal current field. Although many studies have focused on the hydrodynamic environment around radial sand ridges, the knowledge on the genesis of the radial tidal current is still in a ver...
