How do people make use of the tides?

People use tides in the following ways: tidal power generation, tidal aquaculture and tidal tourism.

First, tidal power generation

1, using tidal power generation is to store a large amount of seawater in the reservoir, and use the water level difference to generate electricity through the tidal fluctuation process. The principle of tidal power generation is similar to that of ordinary hydropower generation. By leaving the reservoir, seawater is stored in the reservoir at high tide and stored as potential energy. Then, when the tide ebbs, seawater is released, and the turbine is driven to rotate by the difference of high and low tide levels, and the generator is driven to generate electricity.

2. Tidal energy In a bay or tidal estuary, you can see that the sea or river fluctuates twice a day, which is called tide in the morning and tide at night. Tide, as a natural phenomenon, provides convenience for human navigation, fishing and salt drying. This phenomenon is mainly caused by the tidal force of the moon and the sun and the rotation effect of the earth.

3. To build tidal power stations, there is no need to emigrate or flood the land, and there is no environmental pollution problem. In addition, it can also be combined with tidal power generation to develop comprehensive utilization projects such as reclamation, aquaculture and marine chemical industry.

Second, the tidal law of aquaculture

1. In mudflat culture, tidal method is adopted for mudflat culture. The seawater level is high at high tide, which can be used for aquaculture, and can be evacuated in time at low tide to improve production efficiency.

2. Master the tidal time. The tide changes every day, and the time of high tide is different on different days. Determine the breeding time. The time of feeding fish every day should also be adjusted according to the specific high tide time.

Third, tidal tourism.

1. Tidal tourism means that tourists will experience extreme high tides and low tides at tourist destinations. Many tourist attractions are formed along the coast by using tidal laws, such as the spring tide of Qiantang River in Hangzhou.

2. The Bay of Fundy is the birthplace of the highest tide in the world, with 654.38 billion tons of water coming in and out twice a day. Visitors can play on the wet and soft beach at low tide, pick up shells, catch crabs and build sand castles. Watch the ebb and flow of the tide at high tide and feel the magical charm of nature.
