Sediment exchange in tidal inlets
Title
Sediment exchange in tidal inlets.
Creator
Merz, Clifford Ronald., Florida Atlantic University, Scarlatos, Panagiotis (Pete) D., College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description
Sediment exchange characteristics of tidal inlets subjected to tidal excitations are investigated and the results compared to field data measured at Jupiter Inlet, Florida. A specially written computer program combines inlet/nearshore hydrodynamic expressions with bed-load and suspended load sediment transport relationships to examine the building mechanisms of the near-shore tidal ebb shoal. The ebb tidal flow is modeled as a turbulent, plane jet which includes lateral mixing and entrainment...
Show moreSediment exchange characteristics of tidal inlets subjected to tidal excitations are investigated and the results compared to field data measured at Jupiter Inlet, Florida. A specially written computer program combines inlet/nearshore hydrodynamic expressions with bed-load and suspended load sediment transport relationships to examine the building mechanisms of the near-shore tidal ebb shoal. The ebb tidal flow is modeled as a turbulent, plane jet which includes lateral mixing and entrainment, bottom friction, and offshore bathymetric changes. Flood tidal flow is modeled as a potential flow sink with the water being drawn into the inlet from one or more dominant offshore areas depending on the offshore bottom slope. Sediment transport expressions are evaluated at various locations within the offshore flow field and the sediment deposition depth is calculated at that location over one tidal cycle. Model results are plotted and compared to field data for analysis.

Title
Archaeomalacological Data and Paleoenvironmental Reconstruction at the Jupiter Inlet I Site (8PB34a), Southeast Florida.
Creator
Green, Jennifer, Fradkin, Arlene, Florida Atlantic University, Dorothy F. Schmidt College of Arts and Letters, Department of Anthropology
Abstract/Description
The Jupiter Inlet I site is situated between the Atlantic coast and the Loxahatchee River in southeast Florida. Although excavations were previously conducted, faunal remains were not systematically collected until recently. Molluscan remains recovered in 2010 are examined to reconstruct past ecological habitats, identify which water bodies were used for extracting resources, and document changes in molluscan species over time. Based upon identifications, only brackish and marine species are...

Although excavations were previously conducted, faunal remains were not systematically collected until recently. Molluscan remains recovered in 2010 are examined to reconstruct past ecological habitats, identify which water bodies were used for extracting resources, and document changes in molluscan species over time. Based upon identifications, only brackish and marine species are represented, indicating that the Loxahatchee River was brackish rather than freshwater during the time of occupation and that the site inhabitants were collecting mollusks from both the lagoon and coastal waters.

SPECIES RICHNESS, ABUNDANCE AND OCCURRENCE OF GRASSBED FISHES FROM JUPITER INLET, FLORIDA.
Creator
SNYDER, DAVID BRANT., Florida Atlantic University
Abstract/Description
The fish communities of two seagrass habitats near Jupiter Inlet, Florida, were studied from April 1981 to March 1982 to determine species composition, abundance, richness and occurrence. Monthly collections yielded a total of 23,156 specimens representing 47 families and 146 species. Both sites were numerically dominated by Lagodon rhomboides, Eucinostomus gula, and E. argenteus, which (combined) comprised 63% of the total catch. The presence of young lutjanids, haemulids, serranids and...

Monthly collections yielded a total of 23,156 specimens representing 47 families and 146 species. Both sites were numerically dominated by Lagodon rhomboides, Eucinostomus gula, and E. argenteus, which (combined) comprised 63% of the total catch. The presence of young lutjanids, haemulids, serranids and sphyraenids indicates the role of this area as a nursery ground. Temporal patterns in species composition and abundance were examined through numerical classification. Species composition was more consistent over time than were corresponding abundances. Despite their proximity, the two sites exhibited differences in species composition and abundance. The role of biological, physical and historical factors are discussed in relation to the observed community patterns.

Show moreFor much of the 20th century, mariners in the United States were able to utilize the radio beacon system to aid in navigation; however, in spite of its importance in U.S. nautical history, there has been very little historical or archaeological research published about the system. The Jupiter Inlet Light Station Radio Beacon Building, located at what is today known as the Jupiter Inlet Lighthouse Outstanding Natural Area (JILONA), was part of this coastal network of radio beacons. This thesis involves the methodologies of historical research and terrestrial laser scanning and serves several purposes: to provide JILONA with information about and a digital point cloud of the radio beacon building for future use in a planned museum onsite, to create a much-needed historical narrative of the U.S. radio beacon system, and to aid the Florida Atlantic University Department of Anthropology in future terrestrial laser scanner and modeling efforts. Because the project was undertaken at the request of JILONA, this thesis is to be considered a work of public archaeology.

Show moreThis thesis develops a technique that combines the use of historical geography with photo interpretation and physical geography to reconstruct the predevelopment landcover of an urban area in southeastern Florida. This technique differs from traditional map making methods by utilizing Geographic Information System modeling procedures to create a conceptual map and test it against independent historical maps and accounts. Historical maps and accounts provided new information about the historic landscape that could not be deferred from present physiographic information. The resulting maps had more detail about the most highly altered areas than the conceptual map created from physiographic information.

Show moreThis study analyzed two different inlet management strategies being utilized in Palm Beach County and compared how the downdrift beaches were affected by those strategies throughout the year. Cross-sectional beach profiles, Digital Elevation Model comparisons, and subaerial volumetric change were analyzed for patterns in postplacement beach morphology. Trends in cross- and alongshore grainsize were also analyzed. In Boca Raton the inlet was dredged multiple times a month depending on the level of infilling and the material was placed on the beach immediately downdrift of the inlet. The downdrift beach of the Boca Raton inlet underwent a cycle of shoreline advance in the summer and shoreline retreat in the winter. It was dominated by seasonal processes and its morphologic change was the direct result of shifts in the wind and waves without having a beach more than 60 to 80 meters over the course of the study. In Jupiter, the inlet was dredged on a near annual basis and the material was placed 600m south of the inlet. The size and scope of the larger one-time annual nourishment project resulted in beach widths upwards of 120 meters. The equilibration process that followed in both the cross- and alongshore are what dominated the morphological trends experienced at the site. The results of this study should help coastal managers without current inlet management strategies, compare and overview two different successful inlet management options. For future studies, researchers should extend the monitoring period and extend profiles to the depth of closure to capture. Sediment is a valuable resource, and it’s important for best management practices to maximize benefits and protect downdrift beaches for long-term resiliency of coastal communities.

Creator
Pire-Schmidt, Joaquin., College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description
The analysis and modeling of the coastal farfield behavior of inlet discharge plumes is the key to understanding the fate of pollutants discharged into the ocean. These plumes disperse in chaotic and unpredictable patterns. Theoretical models are based on the average conditions and calibrated to the results of tracer studies. Data and models for freshwater discharges in coastal ocean systems are limited because of the lack of adequate tracers. On February, 2007, a tracer study was conducted...

These plumes disperse in chaotic and unpredictable patterns. Theoretical models are based on the average conditions and calibrated to the results of tracer studies. Data and models for freshwater discharges in coastal ocean systems are limited because of the lack of adequate tracers. On February, 2007, a tracer study was conducted on the Boynton Inlet, Florida, using sulfur hexafluoride (SF6) tracer. The objective of this study is to provide methods of analysis for the sample data collected during the experiment. The detected tracer concentrated in a bolus that migrated north of the inlet at velocities lower than predicted by the current data. The plume was successfully modeled with a Gaussian plume model, with 90% of the SF6 predictions having less than 4.6 pptr error.

Shorelines are a primary source of attraction for the nearly two million tourists who visit Palm Beach County annually. Many of Palm Beach County beaches are located on barrier islands, separated by a series of inlets which serve as access points to the Intracoastal Waterway.

Show moreShorelines are a primary source of attraction for the nearly two million tourists who visit Palm Beach County annually. Many of Palm Beach County beaches are located on barrier islands, separated by a series of inlets which serve as access points to the Intracoastal Waterway. However, inlets are often cited as a source of erosion, through interruption of littoral drift and interaction with nearshore hydrodynamics (e.g., causing wave diffraction or refraction). In an effort to mitigate potential negative impacts of the economically important tidal inlets, Palm Beach County has installed a sand transfer plant (STP) at two inlet locations, the Lake Worth Inlet and the South Lake Worth Inlet. Through analysis of annual aerial photography and beach profile surveys taken between 2000 and 2009, this study will determine what effect, if any, these sand transfer plants are having on the inlet-adjacent shorelines north and south of the two inlets with STP, as well as an inlet without an STP (Boca Inlet). This study hopes to increase the understanding of shoreline dynamics in Palm Beach County, which could recognize important alongshore patterns, such as the occurrence of erosional hot spots, to assist in future mitigation efforts.

Show moreSponges (Phylum Porifera) are hardy organisms persisting and predicted to become more dominant world-wide under climate change scenarios. However, we lack baseline knowledge on sponge biodiversity in transitional areas (subtropical to warm-temperate) that are more susceptible to climate change such as The Indian River Lagoon (IRL) (estuary) and Saint Lucie Reef (northern most coral reef) ecosystems in south Florida. The aims of this master’s thesis are to 1) evaluate if sponge assemblages reflect the previously defined ecotone between subtropical and warm-temperate biomes in the IRL (Chapter one), 2) determine how porifera communities are associated to their respective environment (temperature, water velocity, photosynthetically active radiation, carbonate chemistry, and nutrients) in the IRL and St. Lucie Reef (Chapter two), and 3) establish a distribution baseline for future studies aiming to assess Porifera range shifts during climate change (Chapter one and two). Porifera biodiversity surveys across the IRL and Saint Lucie reef were carried out at different spatial and time scales. Environmental parameters (ocean acidification, temperature and eutrophication) were obtained and compared for sites in Fort Pierce Inlet and St Lucie Reef. Chapter one results show that sponge assemblages do not reflect the previously defined ecotone between subtropical and warm-temperate biomes in the IRL, instead they structure in relation to the inlets (distance from the inlet). The most diverse sponge assemblages are found in Sebastian, Fort Pierce, and Jupiter Inlets, and are significant different among habitats; oyster reefs host a unique assemblage of excavating sponges.
