Coastal engineering

Stream

Engineering; Coastal engineering

(1) A course of water flowing along a bed in the Earth. (2) A current in the sea formed by wind action, water density differences, etc.; e.g. the Gulf Stream. See also current, stream.

Reach

Engineering; Coastal engineering

(1) An arm of the ocean extending into the land, e.g., an estuary. (2) A straight section of restricted waterway that is uniform with respect to discharge, slope, and cross-section.

Dynamic viscosity

Engineering; Coastal engineering

In fluid dynamics, the ratio between the shear stress acting along any plane between neighbouring fluid elements and the rate of deformation of the velocity gradient perpendicular to this plane.

Pass

Engineering; Coastal engineering

In hydrographic usage, a navigable channel through a bar, reef, or shoal, or between closely adjacent islands. On the Gulf of Mexico coast, inlets are often known as passes (e.g., Sabine Pass).

Littoral transport

Engineering; Coastal engineering

The movement of beach material in the littoral zone by waves and currents. Includes movement parallel (long shore drift) and sometimes also perpendicular (cross-shore transport) to the shore.

Diurnal current

Engineering; Coastal engineering

The type of tidal current having only one flood and one ebb period in the tidal day. A rotary current is diurnal if it changes its direction through all points of the compass once each tidal day.

(1) A cylindrical sample extracted from a beach or seabed to investigate the types and depths of sediment layers. _x000D_ (2) An inner, often much less permeable portion of a breakwater or barrier ...
