Description:
Abstract:
Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate. Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion. As a result, there is an increased demand for accurate information regarding past and present shoreline changes. To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.

There is no widely accepted standard for analyzing shoreline change. Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments. The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast. The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

Purpose:
This dataset consists of short-term (1960-2002) shoreline change rates for the Maui North region from Waihee to Kuau. Rate calculations were computed within a GIS using the Digital Shoreline Analysis System (DSAS) version 4.2, an ArcGIS extension developed by the U.S. Geological Survey. Short-term rates of shoreline change were calculated using a weighted linear regression rate based on all available shoreline data between 1960 and 2002. A reference baseline was used as the originating point for the orthogonal transects imported into the DSAS software. The transects intersect each shoreline establishing measurement points, which are then used to calculate short-term rates.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The attributes in this layer are based on the field requirements of the Digital Shoreline Analysis System (DSAS) software (USGS Open-File Report 2008-1278). Transects were constructed manually outside of DSAS and imported into DSAS for calculation of shoreline change rates by the software. The data have been quality checked for intended location and shoreline intersection.
Logical_Consistency_Report:
These data were constructed outside of DSAS and imported to DSAS v4.2, an automated software program which does not perform checks for fidelity of the input features. The transects were visually inspected and sometimes manually adjusted within a standard ArcMap edit session to adjust the position at which an individual transect intersected the shorelines.
Completeness_Report:
This dataset contains the transects imported to the DSAS software application that were used to calculate short-term shoreline change rates for the region.
Lineage:
Process_Step:
Process_Description:
Transect features were generated outside of DSAS and imported to DSAS v4.2 in ArcMap v9.3 for calculation of short-term shoreline change rates for the region. Transects are roughly perpendicular to the historical shorelines and spaced roughly 20 meters along the shore. Please see the DSAS help file distributed with the DSAS software, or visit the USGS website at: <https://pubs.usgs.gov/of/2008/1278/>. This process step and all subsequent process steps were performed by the same person: Bradley Romine.

Process_Step:
Process_Description:
Rate Calculations Performed in DSAS v4.2 using ArcMap v9.3 on selected shoreline features, only (from 1960 to 2002). Additionaly, North Maui includes 86 transect locations where the beach was completely lost to erosion prior to 1960 (replaced by natural or artificial hard shoreline). As a result, all shoreline features at these transects are aligned and all shoreline intersects are equal - indicating no shoreline change (fixed shoreline position) after 1960. Due to a programming issue, DSAS v4.2 crashes when all shoreline intersects are equal. To allow for short-term rate calculations at these transects with DSAS, the shoreline feature class is further edited by removing all but the two most recent shoreline features at transect features where all shorelines are aligned (TransOrder 570, 601-606, 622-624, 627-641, 710-713, 750-752, 757-758, 769-773, 787-796, 800-802, 813-815, 830-832, 840-852, and 867-88). With the shoreline intersection threshold set at 3 (see following parameters used), DSAS will not calculate rates for these transects. After joining the rates table to the transect feature class (see the follow process step 3), the WLR 'null' rates and WCI95 uncertainty values at these transects are replaced with '0' indicating no change.

Parameters Used: shoreline layer=MauiN_shorelines, shoreline date field=DATE_, shoreline uncertainty field name=ACCURACY, the default accuracy=0 (accuracy values provided for all shorelines), shoreline intersection parameters=closest intersection, stats calculations=[weighted linear regression (WLR)], shoreline threshold=3, confidence interval=95%, Output rate table name=NMaui_transects_st_rates_20110715_150745.

Process_Description:
Shoreline rates table (NMaui_transects_st_rates_20110715_150745.dbf) was joined to the transect feature class inwith ArcToolbox > Data Management Tools > Joins > Join Field. Parameters: input dataset: the transect feature class; join field - TransOrder; table to join - NMaui_transects_st_rates_20110715_150745; field in table: TransectID. This method permanently adds the selected attributes to the transect feature class. Following the join, WLR and WCI95 attributes at transects where the beach has been lost (null value = -1, see process step 2 for TransOrder transect numbers) are replaced with 0 - indicating fixed shoreline, no change.

Attribute:
Attribute_Label: WLR
Attribute_Definition:
Short-term weighted least squares (WLR) shoreline change rate in meters per year. A negative value indicates beach erosion (shoreline recession) and a positive value indicates beach accretion (shoreline progradation). In a weighted linear regression, more reliable data are given greater emphasis or weight towards determining a best-fit line. The uncertainty field ("accuracy") of the shoreline feature class is used to calculate the weight. The weight is equal to the inverse of the shoreline uncertainty squared. Therefore, when fitting a trend line, greater emphasis is placed on data points for which the positional uncertainty is smaller. Rates were calculated only at transects with 3 or more historical shoreline intersects (shoreline threshold=3). Transects with less than 3 shoreline intersects were given a null value of -9999, except where the beach was lost to erosion prior to 1960 (see process steps).

Attribute_Domain_Values:
Unrepresentable_Domain:

Attribute:
Attribute_Label: WCI95
Attribute_Definition:
95% confidence interval of WLR shoreline change rate in meters per year. The standard error of the slope with confidence interval describes the uncertainty of the reported rate. The confidence interval is calculated by multiplying the standard error of the slope of the WLR (meters/year) by the two-tailed test statistic at the specified confidence percentage (95). For example, if the reported WLR is 1.34 m/year and the 95 percent confidence interval (WCI95) is 0.5 then you can be 95 percent confident that the true rate of change is 1.34 m +- 0.5 meters/year. Rates and uncertainties were calculated only at transects with 3 or more historical shoreline intersects (shoreline threshold=3). Transects with less than 3 shoreline intersects were given a 'null' value of -9999, except where the beach was lost to erosion prior to 1960 (see process steps).
Attribute_Definition_Source: U.S. Geological Survey
