Type of tide which the presence of a DIURNAL wave is conspicious by a large inequality in either the high or LOW WATER heights with two high waters and two low waters usually occurring each tidal day. In strictness, all tides are mixed, but the name is usually applied without definite limits to the tide intermediate to those predominantly semidiurnal and those predominantly DIURNAL.

Type of tide with a large inequality in either the high and/or low water heights.

The type of tide in which a diurnal wave produces large inequalities in heights and/or durations of successive high and/or low water s. This term applies to the tide s intermediate to those predominantly semidiurnal and those predominantly diurnal.
