Jetty
A pier - Investor / Dock, Jetty - is a technical structure of rivers and lakes, the smaller motor vessels (eg. Ferries create) and (temporarily) fix can.
Jetties are built in places where the water on the shore or near the shore is not deep enough to build a quay wall. Jetties are built from the bank into the water until sufficient water depth allows a safe mooring of a watercraft. Marinas can be located both inside and outside a port . People and goods reach the pier via a bridge or a footbridge. See also pier .
A special form of the jetty is the floating jetty , which floats on the water and is anchored on the bottom or on the bank. It adapts to changing water levels, especially in tidal waters. The best-known example are the pontoons attached to posts on the St. Pauli Landungsbrücken on the Elbe in Hamburg, which also support several buildings. The bridges, which serve as access, rest on the pontoons in a moveable manner along the longitudinal axis so that the various water levels (several meters) can be compensated for by appropriate inclination.
