Book Description
An analysis has been carried out to quantify the sediment transport processes in the Fort Pierce Inlet area and the influence of the inlet. This analysis is formalized as a sediment budget and is based on available survey data, and nourishment and dredging records extending from 1972 to 2002. Available survey data encompass shoreline distances approximately 6 miles north and 15.4 miles south of Fort Pierce Inlet. Three periods were examined in this study: 1972 to 1987, 1987 to 1997, and 1997 to 2002. Average annual sediment volume and shoreline changes derived from the profile data collected during these three intersurvey periods were analyzed. Application of general sediment budget principles established that for the total period 1972 to 2002 there was an average annual deficit of approximately 16,300 yd3/year on the beach south of Fort Pierce Inlet. The general sediment budget indicates that 116,000 yd3/year enter the north boundary of Riomar Beach; 82,000 yd3/year enter the north boundary of St. Lucie County and 57,000 yd3/year leave the south boundary of St. Lucie County. Application of numerical modeling to develop an understanding and predictability of the performance of beach nourishment south of the inlet was carried out as a supporting method to better understand the littoral processes in the area. Recommendations are presented to improve the sediment management practices including sand bypassing to restore balance to the south beaches.

Book Description
Many land-management decisions would be aided by an understanding of the current sediment production and transport regime in a watershed and of the likely effects of planned land use on that regime. Sediment budgeting can provide this information quickly and at low cost if reconnaissance techniques are used to evaluate the budget. Efficient budget construction incorporates seven steps: careful definition of the problem to be addressed; collection of background information; subdivision of the project area into uniform sub-areas; interpretation of aerial photographs; fieldwork; analysis; and checking of results. Methods used in field-work and analysis must be selected according to the types of hillslope and channel processes active, the goals of the analysis, and the level of precision required. Methods for evaluating erosion and sediment transport rates are described, and four examples are given to demonstrate budget applications and construction.

Book Description
The sediment budget is fundamental in coastal science and engineering. Budgets allow estimates to be made of the volume or volume rate of sediment entering and exiting a defined region of the coast and the surplus or deficit remaining in that region. Sediment budgets have been regularly employed with variations in approaches to determine the sources and sinks through application of the primary conservation of mass equation. Historically, sediment budgets have been constructed and displayed on paper or maps. Challenges in constructing a sediment budget include determining the appropriate boundaries of the budget and interior cells; defining the possible range of sediment transport pathways, and the relative magnitude of each; representing the uncertainty associated with values and assumptions in the budget; and testing the sensitivity of the series of budgets to variations in the unknown and temporally-changing values. These challenges are usually addressed by representing a series of budget alternatives that are ultimately drawn on paper, maps, or graphs. Applications of the methodology include detailed local-scale sediment budgets, such as for an inlet or beach fill project, and large-scale sediment budgets for the region surrounding the study area. The local-scale budget has calculation cells representing features on the order of 10s to 100s of meters, and it must be shown separately from the regional sediment budget, with cells ranging from 100s of meters to kilometers. This paper reviews commonly applied sediment budget concepts and introduces new considerations intended to make the sediment budget process more reliable, streamlined, and understandable. The need for both local and regional sediment budgets is discussed, and the utility of combining, or collapsing, cells is shown to be beneficial for local budgets within a regional system.

Book Description
This paper develops preliminary regional sediment budgets for the Northeast and Central regions of the East Coast of Florida as part of "proof-in-concept" testing of Version 2 of the Sediment Budget Analysis System (SBAS2000). Features of SBAS2000, a PC-based method for calculating sediment budgets for local and regional extents that may encompass multiple inlets and beaches, are illustrated through the application. The paper concludes with recommendations for improving regional sediment budget analyses.

Book Description
This fully revised and updated edition introduces the reader to sedimentology and stratigraphic principles, and provides tools for the interpretation of sediments and sedimentary rocks. The processes of formation, transport and deposition of sediment are considered and then applied to develop conceptual models for the full range of sedimentary environments, from deserts to deep seas and reefs to rivers. Different approaches to using stratigraphic principles to date and correlate strata are also considered, in order to provide a comprehensive introduction to all aspects of sedimentology and stratigraphy. The text and figures are designed to be accessible to anyone completely new to the subject, and all of the illustrative material is provided in an accompanying CD-ROM. High-resolution versions of these images can also be downloaded from the companion website for this book at: www.wiley.com/go/nicholssedimentology.
