Exchange Flow Variability between Hypersaline Shark Bay and the Ocean

open access: yesJournal of Marine Science and Engineering, 2018
In Shark Bay, a large hypersaline bay in Western Australia, longitudinal density gradients force gravitational circulation that is important for Bay-ocean exchange. First-time observations of vertical stratification and velocity are presented, confirming

Comparison of computational fluid dynamics and fluid structure interaction models for the performance prediction of tidal current turbines

open access: yesJournal of Ocean Engineering and Science, 2020
CFD models perform rigid body simulations and ignore the hydroelastic behavior of turbine blades. In reality, the tidal turbine blades deform due to the onset flow.

STUDY ON NUMERICAL PREDICTION OF TIDAL CURRENT USING FORECATED WEATHER DATA

open access: yesPROCEEDINGS OF HYDRAULIC ENGINEERING, 2005
The environmental impact assessment is becoming very important with increased public awareness to the environmental issues. In many cases, future conditions of water environment are evaluated referring to the results obtained from numerical simulations that are carried out based on the possible scenario.

Prediction and analysis of tides and tidal currents

open access: yes, 2003
An efficient algorithm of tidal harmonic analysis and prediction is presented in this paper. Some conditions are found by means of the known approximate relationships between the harmonic constants of the tidal constituents. A system of linear equations for least squares solutions under these restricted conditions is obtained. In the case of inadequate

Tidal Current in the Simonoseki Straits and its Prediction

open access: yesJournal of Geography (Chigaku Zasshi), 1949
Tidal current in a, narrow strait can be inferred from the tides at both ends of the strait. That is, if h be the difference of height of S ea surface at both ends, the velocity of tidal current, v, at a point within the strait is expressed by the formulaν=c√2ghwhere c is a constant such that ...
