  • Sandbridge Beach FONSI
    FINDING OF NO SIGNIFICANT IMPACT Issuance of a Negotiated Agreement for Use of Outer Continental Shelf Sand from Sandbridge Shoal in the Sandbridge Beach Erosion Control and Hurricane Protection Project Virginia Beach, Virginia Pursuant to the National Environmental Policy Act (NEPA), Council on Environmental Quality regulations implementing NEPA (40 CFR 1500-1508) and Department of the Interior (DOI) regulations implementing NEPA (43 CFR 46), the Bureau of Ocean Energy Management (BOEM) prepared an environmental assessment (EA) to determine whether the issuance of a negotiated agreement for the use of Outer Continental Shelf (OCS) sand from Sandbridge Shoal Borrow Areas A and B for the Sandbridge Beach Erosion Control and Hurricane Protection Project near Virginia Beach, VA would have a significant effect on the human environment and whether an environmental impact statement (EIS) should be prepared. Several NEPA documents evaluating impacts of the project have been previously prepared by both the US Army Corps of Engineers (USACE) and BOEM. The USACE described the affected environment, evaluated potential environmental impacts (initial construction and nourishment events), and considered alternatives to the proposed action in a 2009 EA. This EA was subsequently updated and adopted by BOEM in 2012 in association with the most recent 2013 Sandbridge nourishment effort (BOEM 2012). Prior to this, BOEM (previously Minerals Management Service [MMS]) was a cooperating agency on several EAs for previous projects (MMS 1997; MMS 2001; MMS 2006). This current EA, prepared by BOEM, supplements and summarizes the aforementioned 2012 analysis. BOEM has reviewed all prior analyses, supplemented additional information as needed, and determined that the potential impacts of the current proposed action have been adequately addressed.

An anabranch cycle E-mail: [email protected] model was developed from previous literature and field observations to illustrate how anabranches within the wandering pattern change from single to multiple channels and vice versa over a number of decades. The model was used to investigate the temporal dynamics of a wandering river through historical case studies and channel characteristics from field data. The wandering Renous River, New Brunswick, was mapped from aerial photographs (1945, 1965, 1983 and 1999) to determine river pattern statistics and for historical analysis of case studies. Five case studies consisting of a stable single channel, newly formed anabranches, anabranches gaining stability following creation, stable anabranches, and an abandoning anabranch were investigated in detail.

  • Stratigraphic Heterogeneity of a Holocene Ooid Tidal Sand Shoal: Lily Bank, Bahamas
    Stratigraphic heterogeneity of a Holocene ooid tidal sand shoal: Lily Bank, Bahamas by Andrew G. Sparks B.A., Franklin & Marshall College, 2008 Submitted to the Department of Geology and the Faculty of the Graduate School of The University of Kansas in partial fulfillment of the requirements for the degree of Master of Science 2011 Advisory Committee: ________________________ Eugene C. Rankey, Chair ________________________ Georgios P. Tsoflias ________________________ Krishnan Srinivasan Date Defended: ____________ The Thesis Committee for Andrew G. Sparks certifies that this is the approved version of the following thesis: Stratigraphic heterogeneity of a Holocene ooid tidal sand shoal: Lily Bank, Bahamas Advisory Committee: ________________________ Eugene C. Rankey, Chair Date Approved: ____________ ii ABSTRACT A central challenge in sedimentary geology is understanding three-dimensional architectural variability, and how it might be predicted. Ooid sand shoals, present in the stratigraphic record from Archean to recent, represent an economically important, but heterogeneous type of carbonate deposit. Whereas the processes influencing the deposition of ooid shoals are well examined and understood, the means by which distinct processes are recorded in the rock record are less constrained. The purpose of this thesis is to understand the relationship among processes, plan-view morphology and stratigraphic variability by examining Lily Bank, a modern tidally dominated Bahamian ooid shoal. Research focuses on two bar form end-members of Lily Bank: transverse shoulder bars oriented normal to flow and flood- and ebb-tide oriented parabolic bars. Results from integrating remote sensing imagery, high frequency seismic (Chirp) data and core characterization (sedimentary structures and granulometric analyses) reveal the stratigraphic record of geomorphic change.
