Why is beach nourishment considered mostly a short-term strategy for fighting beach erosion?
Beach nourishment involves adding sand or sediment to a beach to replenish and restore its shoreline. However, it is considered a short-term strategy for fighting beach erosion because the added sand is eventually eroded by natural forces such as waves, tides, and currents. This erosion can occur relatively quickly, leading to the need for repeated nourishment to maintain the beach's width and protect coastal properties.
Additionally, beach nourishment can be expensive and time-consuming to implement, making it impractical as a long-term solution for areas experiencing ongoing erosion. Other more permanent solutions, such as constructing seawalls or groins, may be more effective in protecting shorelines from erosion in the long run.
