Ocean Tides are pretty useful.
1. During high tides, water rushes into harbours. This helps ships enter and exit harbours safely.
2. High tides make ocean/sea water rush into the mouths of rivers. This helps ships to enter port towns like New York, London, Rotterdam, and Hamburg
3. The temperature at which sea water freezes is much lower than that of river water. In cities like London, due to the high tide, the sea water enters the river and prevents it from freezing.
4. The water accumulation during high tides can be stored behing specially made dams. This can then be used for hydel power.

Usually, any region in the world experiences high tide and low tide twice a day at given intervals. Tides occur due to the gravitational force of the moon and the sun acting on the waters of the Earth, especially the oceans and the seas. The gravitational force of the moon affects the tides more than the Sun as the moon is closer than the Sun.
High tide is when the water level of the ocean increases at a particular area. This is because the gravity of the moon pulls on the water on the side of the earth it is facing and causes water to accumulare in the area it is acting on.
Low tide is when the water level of the ocean decreases or recedes at a particular place. This may be because the sun's gravity is acting on the water present there or that the moon's gravity has pulled some of the water in that region into another region.
Due to the position of the sun, moon ,and Earth, the tides are of two types on which you can research on your own: Neap tide and Spring Tide.

Yes, tides are very useful.  Though the natural occurance of tides is something that cannot be stopped, decreased or increased, people have made use of the phenomenon of tides for many advantages.

As long as people have been sailing in ships, they have noticed that vessels in the ocean have organic matter growing on the hull below the water line.  (This can include barnacles, algea, and even mussels.)  In the days of large wooden sailing vessels, sailors would  navigate their ships to a sandy beach at high tide and tie it off securely.  As the tide would recede, the ship would be effectively beached.  Then, the sailors could careen the vessel.  That is, they would actually set fire to the growth on the hull.  This would not damage the ship, as this was a controlled burn.  At high tide, the ship was untied and floated free.  The resistance to speed created by the organisms was now removed.

Similarly today, the use of tides allows vessels to be beached so that the underside, including the rudders or propellers can be maintained and/or fixed.

Of course, for large vessels engineers have since invented drydocks, allowing a hull to be exposed and dry for any length of time rather than only for a few hours a day.

For the most part, the tides exist and we have to deal with it.  In some places tides are extreme (the Bay of Fundy), in others, they barely change (the Mediterranean Sea).  For those who live/work/build near the shore, it is not a question of whether or not the tides iare useful--because, face it, we can't suddenly outlaw tides and make them go away--but how do we best take the tides into account when undertaking a building project, calculating flood zones, measuring tidal erosion, or determining a rate for flood insurance.

Even if we determined that tides are not useful, there is nothing we can do about them.  They are here to stay and we can either "make the most of it" or we can simply avoid the shore altogether.

Tidal tidal force is due to the role of the sun and the moon, so that the water on the planet generate the phenomenon of cyclical fluctuations. It is not only power generation, fishing, salt production and development of shipping, marine culture, but also for many military operations have a major impact. Historically, there are many successful use of tidal and win the wars.

If it were harnessed, as it is from waterfalls and rivers, the power could be enormous. The French have pioneered this form of tidal power in their huge hydroelectric project near St. Malo in Brittany. Nestling at the foot of the Cotentin peninsula between Dinard and St. Malo, it is able to take advantage of about half the estimated 56 million horse-power which is swept into the Channel by the Atlantic title.

The 24 separate power stations, which are built into the dam, act simultaneously to produce 540 million KWH of electricity a year. This is less than some of the hydro-electric complexes built on the great rivers of Europe, but it is a great deal more reliable, as the rise and fall of the tide is unaffected by adverse weather conditions. These tides may be useful in a sense to produce a great amount of energy but there are a number of problems related to it, both socially and economically.
