Where docks are given sloping sides, openwork timber jetties are generally carried across the slope, at the ends of which vessels can lie in deep water or more solid structures are erected over the slope for supporting coal-tips.
A breakwater structure is designed to absorb the energy of the waves that hit it, either by using mass (e.g. with caissons), or by using a revetment slope (e.g. with rock or concrete armour units). In coastal engineering, a revetment is a land-backed structure whilst a breakwater is a sea-backed structure (i.e. water on both sides).
An old and simple slipway for smaller boats, Ystad, Sweden In its simplest form, a slipway is a plain ramp, typically made of concrete, steel, stone or even wood.The height of the tide can limit the usability of a slip: unless the ramp continues well below the low water level it may not be usable at low tide.
A plan and side view of a generic, empty canal lock. A lock chamber separated from the rest of the canal by an upper pair and a lower pair of mitre gates.The gates in each pair close against each other at an 18° angle to approximate an arch against the water pressure on the "upstream" side of the gates when the water level on the "downstream" side is lower.
The dock's lock was 80 by 20 feet (24.4 by 6.1 m) with a depth at high spring tides of 15.5 feet (4.7 m). As built the dock's sides were of chalkstone covered sloped clay at with a 1 in 3 rise, at the south side a 400 feet (120 m) timber wharf was built, which was rail connected by a sunken line allowing direct loading of wagons from the wharf.
Altars (stepped sides) of South Brisbane Dry Dock, 2007 (HMAS Diamantina to the right) The original section of the South Brisbane Dry Dock is U-shaped with stepped sides while the 1887 extension has sloping sides. [1] The dock was originally 320 feet (98 m) long, but was extended to 420 feet (130 m).
A loading dock or loading bay is an area of a building where goods vehicles (usually road or rail) are loaded and unloaded. They are commonly found on commercial and industrial buildings, and warehouses in particular. Loading docks may be exterior, flush with the building envelope, or fully enclosed.
Slip-off slope (right) and cut bank. The depositional slip-off slope is on the left and a small river cliff on the right. River Ashes Hollow, UK. Schematic cross section of a meandering river channel showing slip-off slope formation. A slip-off slope is a depositional landform that occurs on the inside convex bank of a meandering river.
