 ities preserve the shoreline and make it available for use. This 

 aspect is important because if the shoreline is not protected adequately,

Other structures built to protect the shoreline include bulkheads to 

 hold the shore in place; dikes to prevent flooding and extend reclaimed 

 land, jetties to provide a protective barrier between the sea and ship 

 channels; and groins along beach areas to control sand movement 

 (Figure IV. 2. 25).
