The impact of opening a new inlet to connect the Delaware Bay with adjacent wetlands is described. A hydraulic and stability analysis of the new inlet is presented. The growth of the ebb tidal shoal is identified as the primary cause of beach erosion updrift and downdrift of the new inlet. An estimate of the expected erosion along adjacent beaches is made and compared with erosion occurring during the period between 1994 and 2006.
