Abstract Several methods have been developed such as experimental methods, numerical and computational models for studying the prediction of water level. The purpose of this research is to evaluate and verification Telemac's numerical tidal model in Bushehr Bay waters using measured data. In this regard, the Telemac 2D module has been used to simulate the tide in a A course, 15 days from 01/08...

This paper presents the analysis of the study of the flicker emitted from the 1.2 MW tidal energy converter (TEC), SeaGen, against varying tidal parameters. This paper outlines the main elements of the TEC itself, the environment it is located in and the measurement set up. In this paper, the flicker emitted by the TEC is compared with the different tidal parameters, including flood and ebb tid...

Many nations have expanded their national energy portfolio to ameliorate the effects of climate change and to ensure the security and certainty of energy availability. These efforts have led to scrutiny of marine renewable energy (MRE) as one of several viable new renewable energy sources. In addition to the need to prove the reliability and efficiency of current and wave energy converters, eff...

conducted in the 1980s, is estimated to run to £15 billion. The UK government's Sustainable Development Commission (SDC) estimates that this facility could save 5.6 Mt carbon dioxide per year, in comparison to new-built gas-fired power plants. The carbon footprint of building the barrage would be paid back in 5–8 months, according to the SDC. The concept is based on proven technology, as a simi...

Abstract: Recently, focus has been placed on ocean energy resources because environmental concerns regarding the exploitation of hydrocarbons are increasing. Among the various ocean energy sources, tidal current power (TCP) is recognized as the most promising energy source in terms of predictability and reliability. The enormous energy potential in TCP fields has been exploited by installing TC...

[1] During March–April 1999, 2 weeks of undulating CTD and shipboard acoustic Doppler current profiler surveys revealed the variability of the intense internal tide on the northern edge of Georges Bank. The nature of the internal tide was modulated by episodic surface intrusions of cool, fresh Scotian Shelf Water (SSW), stratifying the otherwise vertically well-mixed outer bank. The introductio...

Global development in terms of increased attention to environmental protection and the finite nature of fossil resources have accelerated the use of renewable energies. Renewable energy portfolio standard (RPS), is a government policy to promote the use of renewable energy in the energy consumption basket.  The RPS stipulates the minimum amount of renewable energy that each electricity supplier...

Spatial resource gradients have been observed at a number of proposed tidal energy sites. However, these gradients are typically quantified using the first or second moments (i.e., mean or standard deviation) of time series which obscures information about the co‐temporal amplitude and phase variation. These co‐temporal variations have a number of interesting implications for power production f...

The generation of clean renewable energy is becoming increasingly critical, as pollution and global warming threaten the environment in which we live. While there are many different kinds of natural energy that can be harnessed, marine tidal energy offers reliability and predictability. However, harnessing energy from tidal flows is inherently difficult, due to the harsh environment. Current me...
