System and method for extraction and processing of river bank coordinates from imagery, generation of an unstructured mesh of the river using river bank positions and available or synthetic bathymetry, application of upstream and downstream boundary forcing data, contingencies for handling missing data, and configuration of multiple realizations of the developed river model.

Tool for rapid configuration of a river model using imagery-based information

System and method for automatically and regularly predicting water level and currents in coastal areas, without operator intervention. The system and method can enable automated operational forecasts at regular time intervals without operator intervention by using a grid and a computer forecast model that allows accurate prediction of tidal heights and currents in complex shoreline and bathymetry regions, single or parallel processing capability, optimal available processor assignment based on the size of computing domain, standard and other tidal database forcing in the open boundary, missing data gap-filling, and wind, bathymetry, and model-derived boundary condition model integration.

Automated method and system for predicting high resolution tidal heights and currents in coastal zones

A system and method for converting structured data to unstructured or structured data, the system and method receiving processing options in a flexible format and a reader selection, executing the reader selection to read data, computing a date time group to iterate through observed and/or modeled data, bilinearly interpolating the structured data to create an unstructured or structured finite element mesh, linearly interpolating data in time if necessary, and storing the populated grid on a computer-readable medium in a format compatible with a target numerical model.

System and method for providing structured data to a structured or unstructured grid

A computer-implemented method for creating an ordered set of boundary data by transforming data from remotely sensed imagery of shorelines is provided. A feature data set and an edge data set are transformed into a set of 3-point boundary segments having a specific head and tail point and the segments are ordered from tail to head in a clockwise or counterclockwise manner relative to the water. Once the 3-point segments are created they are easily linked together into larger segments. These large multi-point segments in turn are linked together to create a closed loop in a predetermined direction, for example, but not limited to, the shorelines for rivers or coastal areas.

Boundary extraction method

Mesh generation and editing tools are provided. The mesh generation and editing tools can be implemented using MATLAB&#xae; and are platform-independent, usable in any number of different operating systems and configurations. The mesh generation tool uses a graphical user interface to receive user inputs of boundary and bathymetry information and automatically generates a mesh based on the input information and user selections of the number of mesh refinements based on the bathymetry that should be run. The mesh generation tool also performs a check of the computing resources needed to construct a mesh with the selected parameters and allows the user to change the parameters before generating the mesh if necessary to avoid excessive resource use. The mesh editing tool includes a fully automated master smoothing script that applies a set of 'best practices' mesh operations to a mesh, and further includes a set of mesh editing tools that can be applied individually to edit and refine a mesh to best suit a user's needs. Meshes generated in accordance with the present invention can include properly formatted ADCIRC grid files (fort.14 file) that can be used to represent coastal ocean dynamics in a discrete computational framework.

An initialized graphical user interface program can produce a plurality of parameter input fields in a graphical user interface. The plurality of parameter input fields can be logically grouped with similar parameter input fields in close approximation to each other in the graphical user interface. The graphical user interface program can then receive a plurality of parameter data from a user can input into the parameter input fields of the graphical user interface program. Based on the received user input parameter data, the graphical user interface program can deactivate one or more parameter input fields. The graphical user interface program can error-check the received input data and provide warnings for any incorrect data. Finally, the graphical user interface program can generate a fort.15 input file based on the parameter input data.

A computer-implemented method for creating an ordered set of shoreline boundary points by transforming data from remotely sensed imagery of shorelines is provided. A water data set and an edge data set are transformed into a set of 3-point boundary segments having a specific head and tail point and the segments are ordered from tail to head in a clockwise or counterclockwise manner relative to the water. Once the 3-point segments are created they are easily linked together into larger segments. These large multi-point segments in turn are linked together to create the shorelines for rivers or coastal areas.

A method for creating a fort.22 input file is provided that comprises the steps of receiving a plurality of user parameters, the plurality of user parameters comprising one or more meteorological data sources, a defined date range, and a data processing request. Then, the one or more meteorological data sources are read for the defined date range. A properly formatted fort.22 file is prepared based on the reader data. Next, it is determined whether a data processing request is present, and if a data processing request is present, an extension/ramping processing program is performed. Finally, the fort.22 file is outputted to a user.
