PERDIDO KEY BEACH NOURISHMENT PROJECT:

GULF ISLANDS NATIONAL SEASHORE

1992 ANNUAL REPORT

1 INTRODUCTION

This report is one in a series of annual summaries of a continuing field project within

Gulf Islands National Seashore at Perdido Key, Florida (Figure 1). Between November 1989 and

September 1990 approximately 4.1 million m3 of dredge material were placed along the eastern 7

km of the Gulf of Mexico shoreline of Perdido Key. From September 1990 to October 1991, an

additional approximately 3 million m3 of material were placed as an underwater deposit between

DNR Monuments R-48 and R-60, extending 3.8 km in the longshore direction and up to 700 m

in the cross-shore direction (see Figure 2).

Earlier reports (Work et al. 1990a, 1990b, 1991a, 1991b, 1991c, 1992a) discussed the

site and physical data collection methods in detail. The focus of this report will be the results of

the field work and physical data collection for 1992. The data describe topographic and

bathymetric changes of the area, waves, currents, tides, sediment sizes, winds, temperatures and

rainfall.

2 DATA COLLECTION

The study area and the data collection sites are shown in Figure 2. Table 1 presents a

chronological summary of the ongoing field efforts since commencement of the project. A

discussion of the data collection and analysis methods can be found in previous reports; only a

brief summary will be included here.

2.1 Hydrographic and Topographic Surveys

The survey equipment and methodology used were unchanged from previous surveys.

The beach profiles were surveyed to approximate depths of 4 to 5 m employing standard

rod-and-level techniques, by first wading and then swimming over the deeper portions of the

profiles. The offshore profile was surveyed by a boat equipped with a fathometer to measure

depths and a microwave rangefinder system to measure horizontal distances. The profile lines

were surveyed using the same azimuth values as in the previous surveys.

During the annual survey in October, 1992 twenty-five profiles were surveyed by boat,

and an additional eight have been surveyed to wading/swimming depth (generally 4-5 m) only, in

order to improve spatial resolution of the evolution of the beach nourishment. A total of eleven

surveys have been conducted to date: the annual bathymetric surveys of 11/89, 9/90, 10/91 and

10/92 and the additional wading/swimming surveys of 1/91, 5/91, 9/91, 1/92, 6/92, 1/93 and

5/93. Data from the four annual surveys are presented in Appendix I.

2.2 Wave/Current/Tide Data

Waves, currents and tides are measured at two stations, one located offshore from the

Ranger Station near DNR Monument R-34, and the other on Caucus Shoal near R-62. Both

stations comprise P-U-V type electronic gages mounted on tetrapod shaped steel frames placed

on the ocean floor. The P-U-V gages consist of two electronic sensors; a pressure transducer and

a electromagnetic current meter. Raw data include a pressure signal and two velocity signals

measured on a horizontal plane perpendicular to each other. All signals are collected once every 6

hours at 1 Hz sampling frequency for a 17 minute duration.

The gage near the Ranger Station is connected by a cable to a shore station which serves

as a link for the remote control operation. The P-U-V data from this gage can be retrieved from

6

the University of Florida via telephone. The gage near Caucus Shoal carries a self contained

storage device which can store data until divers retrieve the package every 3-4 months.

Additional information about wave packages can be found in previous reports by Work et al.,

1990 and 1991.

The P-U-V data are analyzed using directional spectrum methods to obtain wave height,

wave period, wave direction, tide, current velocity and current direction. The computed wave,

current and tide parameters are presented in Appendix II for the period of January to December

1992. There are seven plots per month for each gage. The first four plots present wave related

parameters. These are: Wave period, significant wave height, modal wave direction and the

spreading parameters of the wave spectrum. Wave information is followed by current and tide

variables presented in three plots which show the current velocity, mean current direction and the

tidal elevation.

2.3 Sand Samples

Sand samples are collected at eight locations along the profiles: Dune, mid-beach, berm,

beachface, -1 m, -2 m, -5 m and -8 m. Details about the sampling locations and methodology can

be found in the previous reports by Work et al., 1990 and 1991.

Grain size distributions have been determined by mechanical sieve analysis of each

sample, using a series of twelve U.S. standard sieves with mesh numbers 10, 20, 30, 40, 50, 60,

70, 80, 100, 120, 140, 160. The analysis results are presented in Appendix III. Each figure shows

grain size distributions at a particular location for different sample years. Several characteristic

parameters of the grain size statistics have been analyzed, such as D50 , mean diameter, sorting

index, skewness and kurtosis. In this report only results related to D,, are presented. Other

parameters can be obtained from the authors. A further discussion on sediment characteristics and

spatial/temporal variations in grain sizes can be found in Chapter 4.

2.4 Weather Data

The electronic weather station was installed in June 1990 and collected data until May

1992. In October 1992 it was replaced with a similar unit. This new station operates with a

locally installed data acquisition unit and a storage device. The weather station can be controlled

remotely from the University of Florida and the stored data can be retrieved via telephone. The

data acquisition unit consists of electronic sensors to measure wind velocity, wind direction, air

temperature and rainfall. Data are sampled at 1 Hz frequency and the hourly mean, minimum and

maximum values are saved in the storage device. Approximately once a week an operator calls

the weather station from the University of Florida and retrieves the stored data into a computer.

Appendix IV presents the analyzed data in biweekly time series of wind velocity, wind direction,

air temperature and rainfall.

2.5 Photographic Documentation

Oblique color ground photography has been taken throughout the study to document

changes as the nourished beach evolves. Photography is conducted in conjunction with each

survey. Three photos are generally taken along each profile, viewing to the left along the beach,

perpendicular to the beach and to the right along the beach. The reader may contact the authors

regarding availability of the photographs.

3 ISSUES CURRENTLY UNDER INVESTIGATION

In addition to the information presented in the preceding sections of this report, three

problems are under active study and are discussed here only briefly.

8

3.1 Nearshore Berm Evolution

As noted, following the beach nourishment, approximately 3 million cubic meters of

sand were placed underwater in the area shown in Figure 2. Figures 3 and 4 show cross-sections

through the entire profiles including the profile nourishment area for DNR Monuments R-50 and

R-58. This portion of the nourishment is referred to as "profile nourishment" as distinguished

from the "beach" nourishment which advanced the dry beach and its underwater extension. The

profile nourishment sand was placed by bottom-dump barges such that each placement results in

a more or less identifiable mound with the entire placement appearing as a very "hummocky"

terrain (see Figure 5). Although the original program did not call for study of this portion of the

nourishment, the program scope was modified in Spring, 1992 to include this element. Starting

with the Fall survey of 1992, our annual surveys have encompassed the profile nourishment area.

These efforts have included an extension of the profile lines in the area of profile nourishment

and additional surveys "blanketing" the area. The results from the bathymetric survey in October,

1992 are presented in Figures 5 and 6 which show a three-dimensional view and a contour map

of the nourished area.

The major issues concerning the profile nourishment center around the movement of the

sand ashore with special emphasis on the rate. The rationale for hypothesizing landward

movement is that if the profile was initially in equilibrium and "active", placement of additional

material such as occurred here will result in a profile with an "excess of sand" leading to onshore

sediment transport. Methods currently being employed to address this question include a focus

on the landward edge of the placed material and the bathymetric evolution with particular

emphasis on smoothing of the surface features. Perdido Key was impacted by Hurricane Andrew

in October 1992 with peak significant waves at the two gages measured at 2.7 m. Based upon

analysis of the profile nourishment data, it appears that there may be a small net landward

movement of the underwater berm forming the profile nourishment; however, most of the

evolution is apparent as a "spreading out" of the placed material. This is evident in Figures 3 and

4 for Monuments R-50 and R-58.

In addition to continuing to monitor the profile placement geometry, future efforts will

be directed to the development of methodology for the prediction of the evolution of the

underwater mound, including the rate of landward migration and the smoothing of the surface

features.

3.2 Wave Data Comparison

As discussed previously, a second wave gage was installed in the vicinity of Caucus

Shoals in April, 1992. One purpose of this gage was to identify and document any localized

effects of the Entrance to Pensacola Bay, including the effects of Caucus Shoals. It is expected

that causes of different wave properties at the two sites could include both wave refraction and

wave diffraction, each of which can modify the wave height and wave direction. The effects of

these processes are important as they can cause localized changes in the longshore sediment

transport over the length of the nourishment project. These wave transformation phenomena are

complicated due to the fact that they are functions of the incident wave direction and wave

period. Also wave gages have a tendency to malfunction. The pressure sensor which provides the

basis for determining wave heights is the most reliable element of the gage and the current meter

which provides the basis for establishing wave direction is the least reliable.

At present, efforts are underway to identify portions of the wave records which are

well-suited for identifying the wave transformation effects. Figures 7 and 8 present the wave

characteristics at the two gages during the passage of Hurricane Andrew where it can be seen that

the wave heights were approximately the same, at least until the Caucus Shoals gage ceased to

function near the period of highest waves at about noon on August 24, 1992. During this period,

the wave direction was not well established at either gage.

3.3 Washover Deposits Due to Hurricane Andrew

Hurricane Andrew caused washover deposits along portions of Perdido Key. These

deposits can be characterized as extending approximately 25 m inland from the seaward limit of

the berm and with a thickness of approximately 50 cm. Figure 9 presents an example of a

cross-section (R-54) through the profile showing the washover deposit This deposit of sand has

had the intended purpose of allowing the beach berm to build up naturally rather than to prevent

overwash as would occur if the constructed berm were high as was the case for the 1985 beach

nourishment. A very strong recovery "ridge" is also present in Figure 9. A manuscript is being

developed for journal publication consideration describing this washover event and evaluating

various methods for predicting the washover process and magnitudes.

4 DISCUSSION

Several features of the monitoring program, based on data collected last year merit

discussion as presented below.

4.1 Concentration of Fines

The concentration of fines, located primarily between Ranges R-42 and R-59, are shown

in Figures 10 and 11 respectively for the 5 and 8 m contours, and appear to be decreasing with

time. The origin of these fines is the Pleistocene mud deposits that were excavated in the

dredging operation. The decrease of fines with time is to be expected due to suspension during

energetic wave events which causes suspension of the fines and distribution over wide areas.

However the interpretation of the suspension and transport of fines must be tempered with the

understanding that the distribution can be somewhat "spotty" due to local depressions and thus

the data must be interpreted in the "aggregate" sense rather than on the basis of individual

samples.

4.2 Sediment Characteristics

Sediment characteristics are summarized in Figure 12a for the dune, mid-beach, berm

and beach face locations and in Figure 12b for the Im, 2m, 5m and 8m depths. The solid line in

each of these figures represents the October, 1992 median diameters and the dotted lines

represent the envelope of the size distributions measured including pre-nourishment. It is seen

that in general the 1992 sizes are nearer the lower limit of the envelope than the upper limit. This

is also shown in Figure 13 which shows the temporal variation of the longshore averaged median

values. There is a discernible but slight trend toward the smaller sizes. The reason for this is not

known as many times it is found that new deposits will experience "natural armoring" in which

the finer sand will be removed by wind or water action leaving the less erodible coarser material.

It is possible that Hurricane Andrew contributed to this effect. The two planned future sediment

collections and analysis efforts may provide a basis for further interpretation and understanding.

4.3 Profile Equilibration and Cross-Shore Sediment Transport

The profiles in the nourishment project were placed steeper than those present prior to

the nourishment project. Because the nourishment sediment is compatible to the native, it is

expected that the final equilibrated profile will be very similar to the original. This equilibration

is evident from Figures 14 and 15 which present respectively the alongshore changes in the dry

beach width since November, 1989 and the alongshore change in the position of the 4 m contour

since November, 1989. The post nourishment recession of the dry beach and advancement of the

4 m contour within the nourishment area are indications of a reduction in profile slope. This

slope equilibration is also evident in Figure 16 which presents the average of eight profiles

within the nourishment area. The upper portions of the profiles (down to an elevation of

approximately -0.6 m) appear to have always had approximately the same slope as prior to

nourishment. This could be due to very rapid adjustment before the first post-nourishment survey

or could be due to the placement slope coinciding with the equilibrium slope. It is likely that

both explanations are correct to some degree. Proceeding to greater depths, the offshore bar is not

as well developed as for the pre-nourishment profiles. In fact the average profile one year after

nourishment has only a small indication of a bar whereas after two years, the bar is now better

developed. The slopes seaward of the bar are still substantially steeper than the pre-nourishment

values. The features discussed above are consistent with the fact that the upper portions of the

water column experience more wave energy and thus equilibrate more rapidly than the lower

portions. Profile equilibration was hastened by the maximum 2.7 m peak significant wave

heights (Figures 7 and 8) which occurred during Hurricane Andrew. However waves of this

height had occurred previously at least twice during this study. It is generally believed, based on

very limited data, that cross-shore equilibration requires approximately 2 to 5 years. Although the

data collected in conjunction with this study seem reasonably consistent with this time frame,

they provide more detail in particular the progressive evolution toward equilibrium with

increasing water depth. Finally, it should be noted that these profile equilibration data provide

the best documentation for any beach nourishment project to date. Figure 17 presents, for

comparison the average of five profiles west of the nourishment.

An estimate of the average cross-shore sediment transport can be determined from

sequential average profiles as presented in Figures 16 and 17. These calculated cross-shore

transport rates which are presented in Figures 18 and 19 do not account for sand removed by

longshore transport. It is seen that within the nourished area (Figure 18), the maximum

cross-shore transport during the second year after nourishment is approximately 60% to 70% of

the value during the first year, even with the mobilizing activity of Hurricane Andrew during the

second year. The approximate cross-shore sediment transport for the profiles west of the

nourishment project is shown in Figure 19. Without discussing the details, the peak offshore

transport magnitudes within the nourishment area are approximately 2.5 times greater than the

transport magnitudes west of the nourishment area.
