Tidal waves are periodically occurring waves caused by the gravitational interactions between the Moon, the Earth, and the Sun. Tidal Waves Tidal waves are caused by gravitational interactions between the Moon, the Earth, and the Sun. Seismologists record seismic waves using various instruments like seismometers, accelerometers, and hydrophones. Seismic waves have a wavelength of about 120 miles and generate massive tsunamis. Underwater landslides, earthquakes, large artificial explosions, faulting of the seafloor, and volcanic eruptions cause this type of wave. Seismic Waves A tsunami crashing into a city. This type of wave was first scientifically observed in Lake Geneva by Francois-Alphonse Forel - a renowned Swiss hydrologist, in 1890. Seiche waves are formed by resonances in water bodies often disturbed by seismic activities or meteorological disturbances. Seiche waves are standing waves observed in fully or semi-enclosed water bodies like lakes, bays, reservoirs, harbors, swimming pools, and seas.

Occasionally, most severe storms result in the formation of swells that are longer than 700 m. Often called surface gravity waves, swell waves move along the air-water interface under the influence of gravity and have comparatively longer wavelengths. Swell waves are deeper waves formed when a large amount of energy builds up beneath the ocean's surface, sustained by wind strength and duration of wind blow over a fetch of water. Swell Waves Swell waves caused by a storm in the ocean. The gravity waves that are seen on the air-sea interface are referred to as surface gravity waves, while the gravity waves that are produced within water bodies are known as internal waves. This type of wave is generated by gravitational forces acting on a fluid medium and develops when a fluid is displaced from an equilibrium position. This type of wave is quite common in nature, having a wavelength of less than a few centimeters and a phase speed of about 0.2 to 0.3 meters per second. Often referred to as ripples, capillary waves move along a fluid’s phase boundary and are greatly influenced by the effects of surface tension. Capillary Waves Capillary waves created by falling water droplets. Some of these types have been discussed below. Several distinctive types of waves develop over time. Depending on the water depth, wind speed, wind fetch, and duration of blowing wind, the wind-generated waves can range in size from small ripples to waves having a height of 100 ft. It is to be noted that ocean waves can travel large distances before they reach the shores. These include the wind speed the undisturbed distance of open water over which the wind is blowing without any significant direction change the breadth of the area impacted by the wind fetch the duration of wind flow over the water and the depth of the water body. Many factors determine the formation of waves. Often at the beaches, we can see waves traveling in groups which are referred to as wave trains. No such progression is, however, observed for standing waves.

For progressive waves, the crests and troughs move at a steady speed in a perpendicular direction to themselves. Crests are the highest points of a wave, while troughs are the lowest points. A wave makes the surface water move in a simple harmonic motion as wave crests and troughs. The waves moving towards the shore carry the energy from the wind offshore. These deformations disseminate with the wind speed, whereas the water molecules stay at the same position.

Water waves are generally surface waves or deformations on the sea surface that are a mixture of longitudinal and transverse waves formed by the interaction between the Sun, the Earth, and the Moon. Geography Of Water Waves Cliff washed by the tidal waves on Fingal Beach, Australia.Ī wave is defined as a disturbance on the surface of a water body that moves in a forward motion. Moreover, some abnormal natural phenomena like underwater landslides, volcanic eruptions, and earthquakes can create enormous waves termed tsunamis, leading to widespread damage to coastal environments and human habitations. Although the large and calm waves that come at frequent intervals charm the surfers and beachgoers, the giant rogue waves cause shipwrecks and result in several fatalities. Water waves are indeed a treat to the eyes as they are in a continual set of motion, attracting surfers and beachgoers to the otherwise mundane sea beaches. The waves, however, do not cause the water to move but are actually the movement of energy through the water.

These are called water waves, formed by the wind moving across the free surface of a body of water creating disturbances. While standing on a sea beach, one can observe that the water is physically moving toward the shore and rolling inwards and outwards.
