Tidal Constants.Amounts by which the tide, at a particular place, differs from tide at a port of reference. They may be 'time' or 'height' constants. Time constant applied to time of high or low water at port of reference will give approximate time of high or low water at that particular place. Similarly, height constants will give heights of high and low water.
Tidal Current. Name sometimes given to 'tidal stream'.
Tidal Friction ______ 353____ _______Tide Rode
Tidal Friction. Retardation of Earth's rotation by Moon's tractive effort on atmosphere and waters of Earth; so causing day to be lengthened by about 0.002 of a second in 100 years. In about 50,000,000,000 years the day and month will be of equal length (about 47x24 hours).
Tidal Harbour. Harbour whose depth of water depends on state of tide.
