Timing of tides is related to the Earth’s rotation, and the rotation of the moon around the Earth.Ħ The Sun The second factor controlling the tides is the sun’s gravity.Īverage solar tide = half average lunar tide. Opposite side - bulge produced away from the moon.

Variations in gravitational attraction between the Earth, moon and sun.ĥ The Moon Primary factor that controls the rhythm and height of the tides 2 tidal bulges due to gravitational attraction Side of Earth closest to moon - seawater drawn towards moon. The bore in mahi river is found to be of 2.5m length and 18km/h speed.ģ Tide: are bulges of water produced by the gravitational attraction of the sun and moon on the ocean and by the centrifugal force resulting from rotation of the Earth-sun and Earth-moon systems.Ĥ Why tides occur Refers to cyclic rise and fall of sea water. In india tidal bore is observed in Hoogly river In west coast it is formed near the entrance of sabarmathi and mahi river. It is common in rivers which are shallow, sleep and funnel shaped The formation of tidal bore depends on the strength of incoming tidal wave slope and depth of channel river flow.
