Migration of Dredged Material Mounds: Predictions Based on Field Measurements of Waves, Currents, and Suspended Sediments, Brunswick, GA

Johnson, Charley R. 20 April 2005 (has links)
The state of Georgia has two large ports that are accessed by way of navigable entrance channels. One of these ports is located in Brunswick, Georgia, and is maintained by the United States Army Corps of Engineers via periodic dredging. Sediments removed from the channel are typically pumped several miles offshore of Brunswick and placed in dredged material mounds, thus removing the sediment from the littoral cycle. This offshore placement, while being the most economically viable method, often negatively impacts the sediment budget of the coastal region and causes erosion downdrift of the channel, specifically along Jekyll Island. Onshore placement of the dredged material is not feasible due to increased associated costs and the high fraction of fines present in the material; thus, nearshore placement is a potentially viable alternative. Nearshore placement could possibly reduce erosion rates and provide protection to property from waves and storms. The USACE initiated a thorough field data collection campaign in 2002 to study the possibility of beneficial placement of dredged material. The author analyzed the existing data to predict the rate and direction of sediment movement away from an existing dredge mound. These predictions are then compared to bathymetric survey data in an effort to validate the results and methodologies used for sediment transport predictions. The ultimate goal is to use the results of this study along with numerical models currently being developed by the Corps to assess the possibility of sediments being transported toward the shore thus re-entering the littoral cycle and providing a benefit to the coast of Georgia.

Woodland settlement trends and ritual development in East Central Indiana

Waldron, John D. January 1996 (has links)
This study tested two hypotheses related to Woodland settlement trends and ritual development in East Central Indiana through the example of Mounds State Park in Anderson, Indiana. The first hypothesis was that earthwork enclosure complexes, such as at Anderson, were utilized as central places within a defined territory for the redistribution of resources. The second hypothesis was that a link existed between increasing social stratification in a mixed foraging and horticultural economy and a shift in the function of earthwork complexes resultant from a change in subsistence. It was determined that no conclusions could be made about the validity of these hypotheses due to incomplete data. Suggestions for obtaining relevant data and a theoretical model of earthwork function based on available data are presented. / Department of Anthropology

Håga in context – An analysis of the Håga complex in the Bronze Age landscape of the Mälar Valley region / Håga i kontext – En analys av Hågakomplexet i bronsålderslandskapet i Mälardalen

Elliott, Rachel January 2020 (has links)
The Bronze Age in Middle Sweden is characterized by several key sites and monuments which have been interpreted by previous research to play an overarching role in the elite ruling system in the Mälar Valley region. King Björn’s mound (a.k.a. the Håga mound) and the hillfort Predikstolen represent one of these complexes and has been referred to as a central hub for trading between the south and east as well as a central meeting point for alliance networks throughout the Mälar Valley region. The ritual importance of the site has been particularly relevant to discussions around the mound and accompanying cult house, Hågakyrkan, since the excavation of the mound in 1902-3 by Oscar Almgren. The investigation of the mound’s central cairn dated the monument to the Bronze Age Period IV, and resulted in the discovery of one of the most spectacular burials in Sweden, including gold and bronze artefacts indicative of connections with south Scandinavia, particularly Denmark, and a ritual role typified by Kristian Kristiansen’s institutional divisions of elites based on artefact assemblages. To understand how Håga and other Bronze Age sites have attained the label of ‘ritual’ places in the landscape, a discussion is included on previous research which has defined the parameters of sacred versus profane activity utilizing theories on identity as demonstrated through material expression explored by Kristian Kristiansen (1987, 2011) and Susanne Thedéen (2004). This thesis also utilizes the ritual practice theory defined by Catherine Bell (2009) to identify the repetitive traditions which define cultic practice during the Bronze Age in Middle Sweden in order to understand the unique phenomenon of Håga as compared to other sites in the Mälar Valley region: two sites with established cultic complexes (Broby and Skeke), and two sites characterized by industrial bronze production (Apalle and Hallunda). These sites were additionally chosen based on their position along a north-south inlet system which directly connected Lake Mälaren from the eastern Baltic sea to south Scandinavia and north-western Europe. A comparative analysis of the relevant features and finds of each site as well as a brief overview of the evidence of conflict in southern Scandinavia and Europe are used to contextualize the role Håga served leading up to and following construction of the Håga mound. The delimitations and potential uses of the results are included in the discussion / Bronsåldern i Mellansverige kännetecknas av några nyckelplatser och monument vilka tidigare har tolkats av forskare att ha spelat en övergripande roll för hövdingadömet i Mälardalsområdet. Kung Björns hög (s.k. Hågahögen) och fornborgen Predikstolen utgör ett av dessa komplex och har kallats ett regionalt nav för handel mellan söder och öster, samt en central mötesplats för alliansnätverk i hela Mälardalen. Den rituella vikten har också påpekats som relevant till diskussionen kring Hågahögen och närliggande kulthuset Hågakyrkan sedan undersökningen ledd av Oscar Almgren år 1902-3. Undersökningen av högens centralrösen har daterat monumenten till bronsåldern Period IV och resulterade i upptäckande av en av de mest spektakulära begravningarna i Sverige, vilket inkluderade guld och bronsartefakter som ger indikationer på kopplingar till Sydskandinavien, speciellt Danmark, och den rituella rollen representerat av Kristian Kristiansens institutionella uppdelningar av eliter baserad på artefaktgrupper. För att förstå hur Håga och andra bronsåldersfornlämningar har märkts som ‘rituella’ platser i landskapet, diskuteras tidigare forskning som har definierat begränsningarna av sakral jämfört profan aktivitet med hjälp av teorier om identitet baserad på materiella uttryck utforskat av Kristian Kristiansen (1987, 2011) och Susanne Thedéen (2004). Uppsatsen använder sig också av rituellpraktiksteori eller s.k. ‘ritual practice theory’ definierad av Catherine Bell (2009) för att identifiera återkommande traditionerna som exemplifierar kultpraxis under bronsåldern i Mellansverige, för att kunna förstå den unika karaktär Håga har jämfört andra fornlämningar i Mälardalen: två fornlämningar med etablerade kultkomplex (Broby och Skeke) och två kännetecknade av industriell bronsproduktion (Apalle och Hallunda). De fornlämningar som har valts ut för jämförelse har också baserats på deras position längst det nord-sydliga vattenledssystemet som direkt kopplar Mälaren från Östersjön till Sydskandinavien och nordvästra Europa. En jämförande analys av relevanta anläggningar och fynd från varje fornlämning plus en kort översikt av bevisen för konflikt i Sydskandinavien och Europa används för att kontextualisera Hågas roll innan och efter byggandet av Hågahögen. Begränsningar och potentiella användingsområden av resultaten inkluderas i diskussionen.

Investigations at Kinlock (22SU526), a Freshwater Mussel Shell Ring in the Delta Region of Mississippi

Carlock, James Bradley 11 December 2015 (has links)
Kinlock is a freshwater mussel shell ring site located in Sunflower County in the Mississippi Delta. Little work has been done at freshwater mussel shell rings, and therefore little is known about them. This thesis uses four different data collection methods to answer questions of chronology, site layout, etc. These four methods are controlled surface collection, excavation, coring, and magnetometry. Based on the results of these methods, Kinlock was found to be a Woodland period mussel shell ring with a later Mississippian period component built on top of the shell. This later component consisted of five mounds situated around a plaza. It was also found that the plaza was planned and maintained from the Woodland period through the Mississippian period, until the site was abandoned.

Terminal-occupation community patterns at Lyon's Bluff (22OK520) in Oktibbeha County, Mississippi:sedimentological, molluscan, artifactual, and geophysical evidence

Bierly, S Marshall 03 May 2008 (has links)
Prehistoric cultures are often studied by intrasite artifact variation and quantity without much consideration of how prehistoric populations interacted locally and regionally. Archaeologists can identify and study patterns associated with activities within a specified radius in order to gain an understanding of cultural operations. Identifying a social framework for a prehistoric society allows the investigation of group organization such as status differentiation, shared rituals, and the construction and maintenance of earthworks and living areas. That facilities were constructed for specialized use within a community is evidenced by the presence of earthworks and mounds at many sites (Lewis et al. 1998:16-17). Less well understood is how community patterns reflect social organization. The purpose of this thesis is to better document the number and distribution of structures at Lyon’s Bluff, a Mississippian to Protohistoric-period mound site in Oktibbeha County, Mississippi. The focus will be on the last part of the occupation at the site, i.e., on materials recovered from the plowzone. A method employing molluscan remains and sedimentological evidence is used that allows for the delineation of structure locales using plowzone samples. Additional evidence is provided by artifact distributions and geophysical (magnetic gradiometer) data.
