State of Maine's Beaches in 2009
|
Long Sands Beach, York
Figure 64 |
Two of three beach profiles (LS01 and LS03, Figure 64) were available for comparison. Profile LS02 was lost during the storm, and profiling not resumed. Beach profile data were available from April 1, 2006, April 22, 2007 (immediately post-storm), April 13, 2008, and April 15, 2009.

LS01 = B
Figure 65 |
The post-storm profile exhibited slight changes; there was some loss of elevation in the upper portion of the profile (from 50 m landward), and sediment gain in the offshore (Figure 65). This relates to erosion of sediment and transfer into offshore bars. The 2008 one-year post storm profile showed marked erosion, with the majority of the profile elevations being below those of the immediate post-storm profile. However, the 2009 profile underwent dramatic elevation gains, especially in the nearshore portion of the profile, from about 50-60 m and landward, though the offshore portion basically matches the immediate post-storm shape.

LS03 = B
Figure 66 |
Immediately post-storm, the beach profile showed signs of erosion of the beach and berm, and lowering of the profile between 50-75 m offshore (Figure 66). The 2008 profile showed slight berm recovery, and a gain in elevation of sediment in the offshore portion of the profile, from about 50 m seaward. By 2009, the profile developed a distinct berm feature at the 20 m mark, and although the nearshore developed a steeper slope, the offshore portion of the profile (40 m and seaward) increased in elevation by about 30 cm from 2008 elevations.

Summary
Recovery at Long Sands Beach has been quite good, with significant elevation gains along the profiles. Although some portions of the profiles were very low through 2008, good gains were made in 2009.
