Effects of Proposed Sediment Borrow Pits on Nearshore Wave Climate and Longshore Sediment Transport Rate Along Breton Island, Louisiana


Appendix 3. File Naming Conventions

Skip past contents information

Model results from all four grids are available in geographic information systems (GIS) polygon shapefile format, with all files for a given scenario having a prefix of Gg_Hh_Dd, where g denotes the grid number (1, 2, 3, or 4), and h and d denote the scenario wave height (H) and direction (D) bin number, respectively. So, for example, a prefix of "G1_H1_D1" corresponds to output from grid G1 for a wave height in the lowest bin (0.0 to 0.5 meter) and wave direction in the first bin (0 to 22.5 degrees). A table of scenario characteristics is provided in appendix 1 and is also included in a text file (.txt) zipped with each GIS shapefile. In the case of grid G4, for cases where a borrow pit is included, there is an additional prefix “Pp” where p denotes which proposed borrow pit was considered (1 or 2; fig. 3). The final portion of the filename denotes the output type. For example, G1_H1_D1_wave_height.xxx would contain significant wave height for scenario H1_D1 for grid G1, with various file extensions (.xxx) associated with the GIS shapefile.
