Adjusting a vessel's trim and draught to enhance resistance characteristics is promising strategy improve the energy efficiency of maritime transport. However, vast majority scientific effort has been directed at such gains in deep, unrestricted waters. Shallow confined waters modify flow pressure distribution around ship, altering considerably curve. This study aims elucidate increase effects ...

It has been proved that the geoinformation system of a territorial community is an innovative electronic cartographic resource aimed at maintenance targeted and comfortable assets management, mainly, natural, water, forest, mineral, land resources, engineering, transport, social, tourist infrastructure, investment potential providing for operative communication between residents administration ...

On August 11, 2021, one of the most destructive flood disasters occurred in Western Black Sea Basin Turkey. The resulted death 76 individuals, 30,000 people being affected by disaster. A maximum precipitation depth 400 mm/day was recorded at station, indicating a return period exceeding 500 years for rainfall event.

CFD simulation is used to predict 3D flow inside different configurations. Tunnel ventilation system is one example of CFD application field. Ventilation system is important in all kind of tunnels, road tunnel, rail tunnel or waterway tunnel. In all case CFD is able to predict chronic pollutant dispersion or accidental consequences. This paper presents the model of a waterway tunnel in France i...
