The paper presents validation of the numerical program that computes the distribution of marine current velocities in the Bangka strait and the kinetic energy potential in the form the distributions of available power per area in the Bangka strait. The numerical program used the RANS model where the pressure distribution in the vertical assumed to be hydrostatic. The 2D and 3D numerical program...

The objective of the present work is to assess the global wind and wave resources in the vicinity of some developing countries by evaluating 16-year of data (2001–2016), coming from the European Centre for Medium range Weather Forecast (ECMWF). Until now, not much work has been done to evaluate and use the renewable energy sources from these marine environments. This is because most of the atte...

Due to the diminishing reserves of fossil fuels and increased pollution from exploitation of these fuels, the world is focusing on the renewable energy sources. Energy from tidal waves is one of the most exciting forms of renewable energy because of its consistent nature. Hence, the predictable, consistent and reliable nature of marine currents has enthused the researchers to emphasize on harne...

The English Channel is one of the world's busiest sea areas with intense shipping and port activity juxtaposed with recreation, communications and important conservation areas. Opportunities for marine renewable energy vie with existing activities for space. The current governance of the English Channel is reviewed and found to lack integration between countries, sectors, legislation and scient...

Marine current turbine commercial prototypes have now been deployed and arrays of multiple turbines under design. The tidal flows in which they operate are highly turbulent, but the characteristics of the inflow turbulence have not being considered in present design methods. This work considers the effects of inflow turbulence on the wake behind an actuator disc representation of a marine curre...

There is considerable evidence that environmental variability plays a major role in controlling abundance and distribution of marine populations and that fisheries alter ecosystem functioning and state. This overview documents emergent ecosystem-level ecological patterns and answers meaningful questions regarding the exploitation of marine resources. Do marine ecosystems function differently fr...

the qom formation in naragh area, with 185 meter thickness, is exposed about 25 km northeast of delijan. this formation in the studied area, lithologically, consists of shale, gravely limestone, and sandy limestone, with thin, medium to thick bedded and massive limestons. it disconformably covers the lower red formation and is covered by recent alluvium. in this research, the role of large fora...
