Abstract
Waves are the most important phenomena affecting marine navigation, either in the field of fishing, military or transporting of goods. This paper tries to answer the following important questions: What are the causes and types of waves in the coast of Zuaracity? What are their characteristics? And how do those waves affect the marine navigation and human activities on this coast? The research finds significant results devoted in that: the coast is exposed to on type of waves; wind waves. Zuara coast has never been exposed to waves of Tsunami or landslides. The largest size of the wave forms in winter season due to the wind of north-west which is the fastest wind type that the Libyan coast is exposed to. However, the highest speed is up to 65 knots accompanied with waves reach a height of more than 7 meters. The research also classifies the wind speeds that lead to cancelling ships and boats trips that depend on this work is studying the waves in Zuara coast and the relationship with the waves of Libyan coast and Mediterranean sea. Also, it focuses on the effect of waves on boat speed, design, fuel consumption, and other effects.
Highlights
Waves are the circular movement of water molecules that makes the water surface turbulent and makes floating bodies in vertical persistent movement, which does not stop until the waves calm
5) Waves in Zuara coast are of the wind wave type
6) The size and speed of waves in Zuara coast depend on the wind speed and direction, and its blowing time
Summary
Waves are the circular movement of water molecules that makes the water surface turbulent and makes floating bodies in vertical persistent movement, which does not stop until the waves calm On this basis, the waves affect the activity of humans who ride the sea, and this causes increasing in the size of waves, leading in many cases to stop the activity and the cancelling of a lot of cruises for the reason of fear or cut the risk of adventure to challenge the sea waves. It can be seen that the most human activities affected by the waves are: marine navigation, transport of goods, passengers on ships, fishing and military activities. This study is an initial step to open search in this kind of few studies in the country, and this is what induces me to investigate in this area of research
