Coastal engineering
lower low water (LLW)
Engineering; Coastal engineering
The lower of the two low waters of any tidal day. The single low water occurring daily during periods when the tide is diurnal is considered to be a lower low water.
rip
Engineering; Coastal engineering
A body of water made rough by waves meeting an opposing current, particularly a tidal current; often found where tidal currents are converging and sinking.
poorly-sorted
Engineering; Coastal engineering
Said of a clastic sediment or rock that consists of particles of many sizes mixed together in an unsystematic manner so that no one size class predominates.
poorly-graded
Engineering; Coastal engineering
Said of a clastic sediment or rock that consists of particles of many sizes mixed together in an unsystematic manner so that no one size class predominates.
reference point
Engineering; Coastal engineering
(1) A specified location (in plan elevation) to which measurements are referred. (2) In beach material studies, a specified point within the reference zone.
swash mark
Engineering; Coastal engineering
The thin wavy line of fine sand, mica scales, bits of seaweed, etc., left by the uprush when it recedes from its upward limit of movement on the beach face.
density current
Engineering; Coastal engineering
Phenomenon of relative flow within water due to difference in density. For example, the salt-water wedge is a density current, as is a volcanic nuée ardente.
