Abstract: | An evaluation of coastal processes, shoreline erosion, and shore management options for Conference House Park, New York, USA,
reveals the problems associated with lack of congruence between jurisdictional boundaries and boundaries required for maintenance
of beaches and shorefront park land. Rates of shoreline change are high despite low wave energies because bay beaches contain
small amounts of sand. The park is so narrow in places that the shoreline will soon move out of park boundaries. This condition
will eliminate natural beach resources, restrict access, and create political and administrative problems. Management strategies
include revetment construction, beach nourishment, and acquisition of additional land. Obtaining the maximum length of shorefront
to create a park may be less cost effective in maintaining natural beach resources than obtaining a shorter frontage and more
compact shape that allows for shoreline movement. The problems of managing eroding shorelines in urban estuaries are acute
because space is lacking, the cost of land is high, and the critical nature of shoreline erosion is disguised by low wave
energies and lack of daily beach change. |
