Figure 3. Ludlam Beach showing the barrier island backed by a 2- to 3-inile-wide 

 tidal marsh. Note the 5, 000-foot -seaward offset of the island south 

 of Townsend Inlet relative to Ludlam Beach. Crosshatch shows 

 locations of peat -marsh material exposed on the beach on 8 March 

 1962 (from National Ocein Survey chart 1217). 



Ludlam Beach is 7.5 miles long and 0.25 to 1 mile wide. The higher eleva- 

 tions and most of the inhabited area are along the oceanside of the island. 

 Coastal dunes average 8 to 15 feet in elevation above MSL. On the landward 

 side, the island is largely intertidal marsh dissected by drainage ditches, 

 although recent development has extended into this area along the southern half 

 of the island. The location of the surveyed profile lines at Ludlam Beach is 

 shown in Figure 4 . 



2. Coastal Exposure and Bathymetry . 



The island centerline of Ludlam Beach is offset 800 feet seaward from the 

 barrier island to the north of Corson Inlet and 5,000 feet landward from the 

 barrier island to the south of Townsend Inlet (Fig. 3). Since Ludlam Beach 

 faces the southeast [N. 30° E.), it is fairly sheltered from westerly flow, 

 especially from strong wave-generating northwest winds (Fig. 1). It is par- 

 tially sheltered from northeast winds by the protrusion of the New Jersey coast
