Question

In 3–5 sentences, construct an argument for why beach nourishment is or is not a viable strategy to manage beach erosion.(4 points)

Answer 1

Beach nourishment is not a viable long-term strategy because it only replaces sand temporarily and requires repeated, costly renourishment as sea level rises and storms become more frequent. Recurrent projects create large financial burdens for communities and can harm marine and dune ecosystems when incompatible sand is used or nourishment smothers habitat. Nourishment also fails to address root causes of erosion such as altered sediment supply and development in vulnerable zones, often shifting erosion downdrift. More sustainable options—managed retreat, living shorelines, and restoring sediment supply—are generally more effective and resilient over the long term.
