Description:
Abstract:
This dataset contains projections of shoreline positions and uncertainty bands for future scenarios of sea-level rise. Projections were made using the Coastal Storm Modeling System - Coastal One-line Assimilated Simulation Tool (CoSMoS-COAST), a numerical model forced with global-to-local nested wave models and assimilated with lidar-derived shoreline vectors. Read metadata carefully. Details: Projections of shoreline position in the Central Coast of California are made for scenarios of 25, 50, 75, 92, 100, 125, 150, 175, 200, 250, 300 and 500 centimeters (cm) of SLR by the year 2100. SLR scenarios for 25, 50 and 75 cm are included in the National Research Council (NRC) excel and KMZ files. Four datasets are available for different management conditions: shorelines are allowed to retreat unimpeded past urban structures ("NO Hold the Line") or are limited to this urban boundary ("Hold the Line"), and shorelines are allowed to progress with projected increases in sediment ("Continued Nourishment") or with no projected increases ("No Nourishment"). Projections are made at CoSMoS Monitoring and Observation Points, which represent shore-normal transects spaced 100 m alongshore. The CoSMoS-COAST model solves a coupled set of partial differential equations that resembles conservation of sediment for the series of transects. The model is synthesized from several shoreline models in the scientific literature, which is described in more detail, along with the CoSMoS-Coast methodology, in Vitousek and others 2017. Significant uncertainty is associated with the process noise of the model and unresolved coastal processes. This makes estimation of uncertainty difficult. The uncertainty bands predicted here represent 95 percent confidence bands associated with the modeled shoreline fluctuations. Unresolved processes are not accounted for in the uncertainty bands and could lead to significantly more uncertainty than reported in these predictions.
Purpose:
These data provide an estimate of coastal shoreline position change in response to SLR during the 21st century and are intended for policy makers, resource managers, science researchers, students, and the general public. These data can be used with geographic information systems or other software to identify and assess possible areas of vulnerability. These data are not intended to be used for navigation.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribute values are estimates of shoreline position due to plausible future sea-level rise scenarios and therefore cannot be cross-checked with observations, because observations do not exist. The projections were generated using up-to-date numerical methods and are in line with projections made by previous researchers. Uncertainty bands are included that take seasonal variations in the shoreline as derived using the numerical model into account.
Logical_Consistency_Report:
Data have undergone QA/QC and fall within expected/reasonable ranges.
Completeness_Report:
These geospatial projections are complete. Any gaps in these data, if applicable, are a consequence of nonexisting data or existing data that did not meet quality assurance standards. Users are advised to read the rest of the metadata record and references carefully for additional details.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
A formal accuracy assessment of the projections was conducted for each model output location. The horizontal accuracy (or uncertainty) for each model output point is included within this geospatial dataset and was determined at the 95 percent confidence level.

Overview_Description:
Entity_and_Attribute_Overview:
CoSMoS-COAST Central California (CentralCal) projections of shoreline position for 21st century sea-level rise. The KMZ files consist of shoreline positions changes (displayed as ‘lines’ at defined transects) caused by wave impacts in different named sea-level rise scenarios and management options. Shoreline projections include uncertainty bands and potential wintertime erosion.
Entity_and_Attribute_Detail_Citation:
Shoreline projections and uncertainty are projected at transects (spaced approximately 100m apart alongshore, identified in whole numbers from 4803 to 8047) for Central California. Free parameters and coefficients for numerical models are tuned at each transect location to fit historical data; see Equation 1 from Vitousek and others (2017) for details and definitions. Coefficients and data used to tune individual transect models are listed at each transect location. Shoreline positions at midpoints along each SLR curve are also provided.
