Today, the widespread use of fossil fuels is caused many problems in the world, which include: Ozone depletion, the increase carbon dioxide in the atmosphere, growing recognition of climate change impacts and decreasing fossil fuel resources. These issues have led to an increased interest in the mass generation of electricity from renewable sources such tidal energy. The Khowr-e Musa Estuary, l...

a major part of tidal energy is usually dissipated by the interaction of tidal currents with bottom topography. gulf of oman is a marginal sea which has variable topography and its dominant tidal constituent is m2 semi-diurnal tide. in this paper, the interaction of barotropic tidal current with bottom topography is evaluated. this phenomenon causes the formation of internal tide. internal tide...

Tidal power can play a vital role in integrating as new source of renewable energy to the off-grid power connection in isolated areas, namely Sandwip, in Bangladesh. It can reduce the present energy crisis and improve the social, environmental and economic perspective of Bangladesh. Tidal energy is becoming popular around the world due to its own facilities. The development of any country large...

Tidal stream energy has the potential to make a significant contribu‐ tion to energy mix in the future. Accurate modelling and visualisation of both tidal resource and array layout enhances understanding of in-stream tidal behav‐ iour leading to improvements in site identification and optimal positioning of individual turbines. A realistic representation of blade loading conditions will aid des...

Tidal Stream Energy Extraction in Coastal Basins A thesis submitted for the degree of Doctor of Philosophy Scott Draper St Catherine's College, Oxford Trinity Term 2011 In recent years the extraction of energy from tidal streams has grown in popularity as a potential source of clean renewable energy. To extract this energy, tidal devices, resembling underwater turbines or hydroplanes, are deplo...

Tidal energy has the potential to play a key role in meeting renewable energy targets set out by the United Kingdom (UK) government and devolved administrations. Attention has been drawn to this resource as a number of locations with high tidal current velocity have recently been leased by the Crown Estate for commercial development. Although tides are periodic and predictable, there are times ...

An overview of the current design practices in the field of Renewable Energy (RE) is presented; also paper delineates the background to the development of unique and novel techniques for power generation using the kinetic energy of tidal streams and other marine currents. Also this study focuses only on vertical axis tidal turbine. Tidal stream devices have been developed as an alternative meth...

A tidal bore may occur in a macro-tidal estuary when the tidal range exceeds 4.5–6 m and the estuary bathymetry amplifies the tidal wave. Its upstream propagation induces a strong mixing of the estuarine waters. The propagation of undular tidal bores was investigated herein to study the effect of bridge piers on the bore propagation and characteristics. Both the tidal bore profile and the turbu...
