what man-made features cause change on shoreline?
100603
Jetties and sea walls cause sand and silt to be deposited on their down-current side.  Example: The long jetty near the airport.\n\nWetlands are drained for development thus removing the buffer that wetlands provide against storm surges and flooding.  Example: Burnt Bridge Creek area - Lacamas Creek Enterprises Inc. filled approximately 1.2 acres of wetlands

There are a couple ways. Hot spots can build up islands through volcanic activity, like Hawaii. Some islands can be created by subduction volcanism (Japan). Other islands can be uplifted at convergent or possibly transverse plate boundaries.\n\nIslands can also be created by erosion and inundation, as in a case of sea level rise where the water covers low lying areas while higher areas get "separated" from the land by water (St. Lawrence Island in Alaska). Glaciers can scour channels around large land masses, then recede and the channels can become filled with water to surround the land masses and make them islands. Manhattan Island was actually created by a continental glacier pushing a bunch of sediment out into the ocean and then receeding (it is a moraine).\n\nSome islands can be created purely by sediment deposition, such as those at the mouths of deltas.

over time the water 'hitting' the coast erodes it by removing the particles (happens over long peiods of time)

Mudslides(flows can be helped and are caused from \nlack of plants,roots ,brush,trees ect on the sides of hills.With the escavation and creation of new\nhousing ect and for the clean hillside look.The\nimportance of the undergrowth of grass ,trees ect \nhave been depleted and not replaced.They have \nprograms for beaches and hillsides,even in foreign\ncountries that realise the importance of root and plant systems in hillside lands.The winding and \nweb patterned root systems of these plants,trees\nacts like a "net" and the plants themselves and erosion barrier.

Tides vary in strength depending on whether the sun and moon are working together or against each other.  Also the shape of the coast that the tide washes against can magnify it (like a converging bay) or dimminish it (like a diverging promontory jutting into the sea).  Therefore, the location is key.  For substantial power generation, a massive structure may be required which is a huge investment.  The project may be opposed for esthetic reasons (some like big tides?) and economic reasons (access for ships and pleasure boats may be affected?).  Such structures can change the natural movement of sand and beaches, especially during and follopowing huge storms.  But one big problem remains, that you can not harness the tides without influencing and changing them.  The wrong structure could dimminish the very tide that you wish to harness.  Therefore, the tides can be harnessed (some have been) but not without many problems to overcome.  Computer models can help only with the technical problems to avoid abandoned investments.

Coastal erosion is also known to produce offshore bars which, if big enough, can be vegetated and become islands.\n\nRivers can also meander around bits of land on the floodplain and cut them off from the rest of the earth, forming islands.

When I was Hawaii recently I went to visit my favorite beach, Kahana Bay, and was very disappointed that the area was allowed to accumulate lots of garbage and floating debris was washed up all over the shore.  I would love to see this cleaned up and returned to the beautiful way I remember it.

its the product of erosion....soil that has been eroded from rocks become sand in the sea...then when waves move they carry the sand to the shore...

A one that gradually increases in size before it reaches the shore.

1. different and more efficient road road surfacing. Too many dirt roads in this state.\n2. More hook up to city water and sewage in the large towns\n3. stop dumping partially treated sewage in the river

NONE.  All things were created!  Things adapt to changing environments, but they never turn into something entirely new.

The represent two different ends of the spectrum of erosion. A cove tends to be a sheltered less energetic environment than a point exposed to the full force of the ocean waves - therefore waves either deposit or do not erode sand from coves, while wave erosion of points keeps them cut back to exposed rock - carrying away all finer grained materials.

Currents flow in complex patterns affected by wind, the water's salinity and heat content, bottom topography, and the earth's rotation.

Sounds like you want your homework done by someone else..lol. Question is confusing.  15 effects of erosion, ok (you do the work, there)...what do you meant "its issue of this topic?"  the topic of environment? You're not clear. Look below for links.
