Title:
Point shapefile of probability of shoreline change along the U.S. Atlantic Coast (ProbSLC_AtlanticData.shp)
Abstract:
During the 21st century, sea-level rise will have a wide range of effects on coastal environments, human development and infrastructure in coastal areas. Consequently there is a need to develop modeling or other analytical approaches that can be used to evaluate potential impacts to inform coastal management. This shapefile provides the data that were used to develop and evaluate the performance of a Bayesian network (BN) that was developed to predict long-term shoreline change associated with sea-level rise. The data consist of information compiled as part of the U.S. Geological Survey Coastal Vulnerability Index for the U.S. Atlantic coast. In this work, the Bayesian network is used to define relationships between driving forces, geologic constraints, and coastal response which are represented by observations of local rates of relative sea-level rise, wave height, tide range, geomorphic classification, coastal slope, and shoreline change rate. Using this information, the BN is used to make probabilistic predictions of shoreline retreat in response to different future sea-level rise rates.

Why was the data set created?

This dataset consists of information extracted from the Coastal Vulnerability Index (Thieler and Hammar-Klose, 1999; Hammar-Klose and Thieler, 2001) that were used to inform a Bayesian network that was used to calculate the probability of long-term shoreline change associated with sea-level rise. The data included with this report contain both input data values from the Coastal Vulnerability Index and the discrete probability distributions of long-term shoreline change that were calculated using the Bayesian network.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: May-2009 (process 1 of 7)
    Input data from the Coastal Vulnerability Index (CVI) were clipped using ArcMap 9.3 to include only the open ocean-facing shores of the U.S. Atlantic Coast. All ocean-facing segments of the source shapefile that corresponded with the spatial extent of Dolan and others (1985) were highlighted within ArcMap. These data were exported by right-clicking on the file in the table of contents and choosing Data > Export. The selected features were saved to a new polyline shapefile. This process step and all subsequent steps were performed by the same person: Benjamin T. Gutierrez Person who carried out this activity:

    bgutierrez@usgs.gov
    Date: May-2009 (process 2 of 7)
    The original source data consisted of polyline segments of varying length (~0.5 - 5 km). These were converted to points that reflected the centroid of the original polyline segments using XTools Pro version 7.1 (Build 738), Feature Conversions > polylines to points. The center point was specified as centroid location. The shapefile was then exported as an Excel 2007 file.
    Date: Mar-2010 (process 3 of 7)
    Shoreline change data for the shores of the Chesapeake and Delaware Bays were acquired from Dolan and Peatross (1992) and replaced those included with the original CVI dataset for the same locations.
    Date: Nov-2010 (process 4 of 7)
    Shoreline change probabilities were calculated using a Bayesian network that was designed and implemented using the Netica software package (Norsys). Each input scenario in the data set was evaluated systematically using MATLAB version 7.11 to input each scenario into the Bayeisan Network to then calculate the probability of shoreline change for those specific conditions. The resulting discrete probability distribution was then output and included in an Excel 2007 file alongside the corresponding input data.
    Date: Nov-2010 (process 5 of 7)
    The Excel 2007 file was then imported into ArcMap version 9.3 and converted to a shapefile.
    Date: 02-Oct-2019 (process 6 of 7)
    Edits to the metadata were made to fix any errors that MP v 2.9.50 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The metadata date (but not the metadata creator) was edited to reflect the date of these changes. USGS Thesaurus keywords were added, and thesauri with no keywords were deleted. The publication DOI link was added to the online linkage. Person who carried out this activity:

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    The attributes of this dataset are based on the Digital Data Series by Hammar-Klose and Thieler (2001, Coastal Vulnerability to sea-level rise: a preliminary database for the U.S. Atlantic, Pacific, and Gulf of Mexico coasts, U.S. Geological Survey Digital Data Series 68). Segements of these data have been updated using shoreline change data from Dolan and Peatross (1992, Data supplement to the U.S. Geological Survey 1:2,000,000-scale map of shoreline erosion and accretion of the mid-Atlantic coast, U.S. Geological Survey Open File Report 92-377, 116p.
  2. How accurate are the geographic locations?
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    These data were derived from Hammar-Klose and Thieler (2001). The data were edited only to include open ocean-facing coasts of the Atlantic coast and portions of the Delaware and Chesapeake Bays of the United States that corresponded to the spatial extent of shoreline change data provided in Dolan and others (1985, Coastal erosion and accretion, in National Atlas of the United States of America, 1 sheet, U.S. Geological Survey, Reston, Va.) which were part of the source data for the Hammar-Klose and Thieler (2001) data series. Segments of these data have been updated using shoreline change data from Dolan and Peatross (1992).
  5. How consistent are the relationships among the observations, including topology?
    This shapefile consists of point data compiled from mulitple sources. The shoreline change data from Hammar-Klose and Thieler (2001) was replaced along the Chesapeake and Delaware Bays with data from Dolan and Peatross (1992). The source datasets were originally in varying-length polylines and were converted to points (using the centroid of each line) for display and publication purposes.
