MIDTOWN BEACH NOURISHMENT PROJECT IN PALM BEACH, FLORIDA
October 1995 to April 1997
INTRODUCTION
During the period October 18, 1995 to December 10, 1995, approximately 880,000 cubic yards of sand were dredged from a borrow area extending from approximately 2,000 feet south to 4,800 feet south of the south jetty at Lake Worth Entrance and placed along portions of Midtown Beach section in the Town of Palm Beach, Florida. The project specifications required placement of 800,000 cubic yards; thus the excess 80,000 cubic yards is "overfill". As shown in Figure 1, the cross-shore dimensions of the borrow area varied from 1,600 feet at its northern end to 2,500 feet at its southern end. The original depths at the borrow area site varied from 25 to 35 feet and the dredged depths were approximately 40 feet deep. The dredged sand was placed along the Midtown Beach as nourishment extending from via Bethesda at the north end to via Marina at the south end, a distance of approximately 5,030 feet. To provide stability to the nourishment project, eleven groins were constructed. The locations of these groins are shown in Figure 1 along with the borrow area and the approximate platform of the nourished beach. Sea Systems, Inc has conducted a pre-nourishment and three post-nourishment surveys to document the performance of the project. The purpose of this report is to present the results of an analysis of these four surveys.
The dates of the surveys are presented in Table 1. As can be seen from Table 1, although the placement of material was completed in December, the first post-nourishment survey was not completed until April 9, 1996 due to the activities related to groin construction. During the period between completion of nourishment and the first post-nourishment survey, a significant northeaster occurred (March 8-10, 1996) which undoubtedly caused the transport of some sand from the nourished beach. Thus, since the first post-nourishment survey post-dated the March storm, the first post-nourishment survey does not reflect the total amount of sand placed.

RESULTS

The results are presented in various forms, including examples of beach profiles, longshore distribution of additional volumes as a function of time, longshore distribution of additional beach width as a function of time and total additional areas and volumes as functions of time.
Beach Profiles
Figures 2 and 3 present examples of the available beach profiles in the borrow area and in the nourishment area, respectively. All of the profile surveys are presented in Appendix A. Figure 2, representing the profiles at DNR Monument R-79 is located approximately 3300 feet south of the south jetty. It is seen that the pre-nourishment depths in the borrow area ranged from approximately 25 feet to 35 feet and that the post-nourishment depths range up to approximately 40 feet. Figure 3 depicts the pre- and post-nourished profiles at Monument R-97D1 29 which is located at approximately mid-length of the nourishment project. This is in an area where the shoreline revetment is located and prior to the nourishment, there was no beach at mean tide as the water was at the revetment. After nourishment, there was approximately 150 feet of additional dry beach present. The presence of the natural offshore reef extending from 700 feet to 1,200 feet from the seawall is evident. Also evident from this plot is that there was very little change from the April post-nourishment survey to the August post-nourishment survey; however, there was a somewhat greater change from August 1996 to April 1997. As will be evident later, there were only minor changes in both volume and dry beach area within the longshore extent of the project during the April 1996 to August 1996 period, but substantially greater changes from August 1996 to April 1997.
Longshore Distributions of Volume Densities and Plan Areas
Figure 4 presents the longshore distribution of additional volume density along the project area. It is seen that on average, an additional 150 cubic yards per foot of beach front were present in April 1996 along the 5,030 feet of project area. Between the April 1996 and October 1996 surveys, although there had been some redistribution of volume, there had been very little volume loss. Between August 1996 and April 1997, the losses have been considerably greater. The volume densities in Figure 4 represent the volumes to approximately 1,000 feet seaward from the monument. As can be seen by referring to Figure 3 and the figures in Appendix A, this distance extends out onto the natural reef.
Figure 5 presents the longshore distribution of additional beach width within the project area in a form similar to that presented for volume density. Substantial similarities exist between the volume densities and additional beach widths. The changes between the April and August surveys are relatively small; however, the changes from August 1996 to April 1997 are greater.

SUMMARY AND CONCLUSIONS
Based on the three post-nourishment surveys, the Midtown Beach project has performed quite well, generally maintaining the volume and plan area from the first post-nourishment survey to the second and third surveys. The first five month post-nourishment period (April 1996 to August 1996) is for a generally mild weather period whereas the second seven month post-nourishment period (August 1996 to April 1997) is for a more generally energetic wave period. The area and volume changes reflect the wave energy levels of these periods. Accepting the reported placement volume of 880,000 cubic yards, the maximum loss to April 1997 within the placement area is approximately 31%. Moreover, approximately one-half of this loss occurred during the period when the groins were not in place and during the intense March 1996 storm. The losses during the seven month winter period, August 1996 to April 1997 within the placement area represent approximately 15.9 % of the material placed. The total losses during the one year period April 1996 to April 1997 within the placement area may represent the losses to be expected during a typical first year after nourishment and amount to 16.3 %.The total losses within the surveyed area during this one-year period are 6.3 %. Nourishment losses are expected to decrease as the effective length of the project becomes greater due to spreading of sand from the nourishment area. Additionally, at the Midtown Project, the stabilizing effects of the groins should start to occur soon. Two final points are relevant to evaluating project performance: (1) The project performance to date reflects two winter seasons. Very little change appears to occur during the summer months, and (2) Since permit conditions require renourishment when 40% of the project volume has been transported from the placement area, this would occur when the volume remaining is 480,000 cubic yards.
