jetties help stop erosion
jetties are constructive forces
Jetties do not protect a beach, jetties are built to tie boats up to. The structures built to protect a beach are called seawalls, sea defences and groins.
there are a lot!
otters are commonly known to be seen on pier rocks and some like to live on jetties. so its more of the breed.
The plural of jetty is jetties.

Jetties are usually for the purpose of controlling erosion in inlets and rivers. They also serve the purpose of protecting harbors and river entrances from the ocean from heavy wave action and storm damage.
they stop long shore drift

Erosion can be temporarily prevented from unnatural causes. One example is building jetties so water doesn't erode sand. Jetties can also ruin beaches by collecting sand from the water that needs to be brought back to beaches.
They traps sand, which stop the normal flow of sand along the shoreline.

These two terms are often used interchangeably to refer to the short, shore perpendicular structures that are built along a shoreline to hold sand in place. However, technically speaking, groins and jetties are not the same thing. Groins are the smaller shore perpendicular structures, built to trap sand and stabilize a sandy beach. Jetties are large structures typically used to stabilize inlet channels.
Help me. I doing a debate in my Geology class tomorrow. I am on the against side. Give me three points of why should I be against beach nourishments, jetties or groin. Thanks
segulls rock crabs starfish( ocasonally ) minows and/or krill shrimp sea robins or skates crabs that live in the jetties HOPE THIS HELPED U :)
Yes, the Potomac river is the western border of Washington DC. There are many jetties and piers and boat houses on the Washington DC side of the river that will allow you direct access.
Answerer: The load arm is a balanced mechanical arm use mainly at jetties to load and discharge petroluem or chemicals to a tank onshore. It is used at truck loading bay as well.

Also the load arm is the part of a lever where the load is applied, which is the opposite of effort arm which is where the effort or work is applied.
ocean groins are human-built structures put at a right angle to the shoreline to prevent the erosion, deposition and weathering of the shore. Jetties and breakwaters are also used for this reason. http://en.wikipedia.org/wiki/File:53sitges.jpg
Jetties and groynes are both structures that stick out from the coast, but which have different functions. A jetty is usually constructed on piles to allow access to boats moored to it. In this way, a harbour can increase its mooring capacity (which increases revenue). Harbours tend to be in sheltered locations, such as river estuaries. Groynes are built in areas which are prone to erosion. They can be made of wood, but are more often constructed from stones. Their purpose is to act as a barrier to erosion, and also to prevent beach sediment being moved along the shore. They form part of strategies for managing coastal erosion.
jetties can effect a shore by protect beaches by trapping pebbles and sand that normally flow down the cost with the current. But thy can also let the sand left over on the beach erode faster.
There are parts designed for swimming (jetties etc), however some parts are pretty busy with boat traffic etc, so it would be silly swimming there. not sure if the is a rule against it tho. ohh and the jelly fish
a place on the coast where vessels may find shelter, especially one protected from rough water by piers, jetties, and other artificial structures:
