The models examined the influence of hydrologic and physical variables related to long-term and storm-derived overwash and back-barrier shoreline change. Input variables were constructed into a Bayesian Network (BN) using Netica, a computer program created by NORSYS Software Corporation that allows users to work with belief networks and influence diagrams. Each model is tested on its ability to predict changes in long-term and event-driven (i.e., Hurricane Sandy-induced) backshore and sandline change based on learned correlations from the input variables across the domain. Using the input hydrodynamic and geomorphic data, the BN is constrained to produce a prediction of an updated conditional probability of backshore or sandline change at each location. To evaluate the ability of the BN to reproduce the observations used to train the model, the skill, log likelihood ratio and probability predictions were utilized. These data are the probability and skill metrics for the long-term beach sandline change model. Purpose: The beach sandline change model will be used to examine how geophysical and hydrodynamic variables influence both long-term and storm-driven dynamics of barrier islands overwash and erosion. This information is critical to understanding and predicting the implications of future sea-level and storm impacts on barrier islands and estuaries.

Online_Linkage: https://doi.org/10.1002/2015EF000331 Data_Quality_Information: Logical_Consistency_Report: Data values were checked for logical consistency. Predicted probabilities range from 0 to 1, where 0 is least likely and 1 is most likely to fall within the identified bin. The log-transform of the likelihood ratio can be negative or positive values; however, positive values show an improvement over the prior. The Bayesian mean and predicted most likely value should fall within a reasonable estimate of sandline change parameters of the case (calibration) dataset. Completeness_Report: Data are complete. In some cases, all modeled variables were not available for each observation; however, Bayesian Networks can learn from a file of cases, relying on complete observations to create a maximum likelihood Bayes net. For this model, the expectation-maximization (EM) learning algorithm in Netica was used. At locations where some or all of the data are missing (e.g., due to differences in the spatial resolution of the datasets) predictions can still be made since missing data are taken into account with prediction uncertainty. For example, at worst, with no specific inputs, the BN prediction returns the prior distribution of the output variable, which reflects the spatial variability of that variable over the entire study area.

Process_Step: Process_Description: The Bayesian network (BN) for back-barrier shoreline (backshore) change was constructed in Netica using the following variables: barrier island height, barrier island width, estuary depth, estuary width, maximum storm-driven wave height, long-term and storm-driven (Hurricane Sandy) ocean shoreline change, and long-term and storm-driven backshore change. Calibration (case) data were generated using a transect method in Esri ArcGIS (Version 10.3.1.4959) from pre-Hurricane Sandy lidar, imagery, and hydrodynamic models. The BN was constrained using the case data to produce a prediction of a conditional probability of back-barrier shoreline (backshore) change. These case data and methods were previously published in Terrano, J.F. and Smith, K.E.L., 2015, Estuarine Shoreline and Barrier-Island Sandline Change Assessment: U.S. Geological Survey data release, https://doi.org/10.5066/F71Z42HN. The BN predictions are produced at the same spatial scale as the input variables. At locations where some or all of the data are missing (e.g., due to differences in the spatial resolution of the datasets) predictions can still be made since missing data are taken into account with prediction uncertainty. For example, at worst, with no specific inputs, the BN prediction returns the prior distribution of the output variable, which reflects the spatial variability of that variable over the entire study area. To evaluate the ability of the BN to reproduce the observations used to train the model, the skill, and log likelihood ratio are utilized. The BN was loaded into MatLab and hindcast to predict the best possible skill for back-barrier shoreline or beach sandline change. The equation used to compute the skill and likelihood ratios are given in equations 4 and 5 in Plant and others (2016). Predicted probabilities and skill metrics were output from Matlab into tabular form to produce this summary dataset.
