This publication is part of a data series for the entire Oregon coast (see map below for project areas):
Each project area has the following data organized by either the computational grid or the whole project. (See the Tsunami Project Areas and Grid Index Map PDF.) The Bandon, Coos Bay, and South Coast projects have all of their data organized by project area. The Central Coast, Clatsop, and Tillamook projects have all of the data organized by both project area and by computational grid. All projects areas have the following data provided in these publications:

EXPLANATION OF FILES INCLUDED WITH THIS PUBLICATION
This publication is part of a data series for the entire Oregon coast. The publications are made up of six project areas (from North to South): Clatsop, Tillamook, Central Coast, Coos Bay, Bandon, and South Coast. Each project area has data organized by either the computational grid or the whole project area. The Bandon, Coos Bay, and South Coast projects have all of their data organized by project area. The Central Coast, Clatsop, and Tillamook projects have all of their data organized by both project area and by computational grid.
The purpose of this publication is to release model output files of the maximum tsunami wave elevations, maximum velocities, and maximum flow depths, over the course of the entire simulation, for specific locations. These files also include post-earthquake subsidence values, pre- and post-earthquake topography, and wet/dry attributes. There are two .pdf booklets for the project area with charts depicting the modeled tsunami wave heights and velocities as they arrive at gauge stations simulated in the computer model. The data provided is for all of the 7 tsunami scenarios published by DOGAMI (SM, M, L, XL, XXL, AK64, and AKMax).
Please read the Open-File Report O-13-19 Tsunami Inundation Scenarios for Oregon report (also provided as part of this publication) for more detailed information on the methodologies used to create these data.
The Clatsop Project Area covers the entire coastline of Clatsop County and extends up the Columbia River to include the City of Astoria. It does not include the Washington (north) side of the Columbia River. The Tillamook Project Area publication contains data adjacent and to the south of this project area.
The Clatsop Project Area is made up of two computational grids; Grid A and B. Therefore, the two Grid_**grid name** folders contain the raw model output data in ascii format (.txt files) including: pre- and post-earthquake bathymetry, wet/dry values, maximum wave elevation, maximum flow depth, maximum velocity, and east/west and north/south component velocity data. These folders also contain the raw wave time history data (elevation and velocity) for simulated gauge stations in ascii format (.txt files). These data are organized by grid within the Grid_Data folder. All other files provided within this publication are not grid specific, rather they are for the entire project area and located in the ProjectArea_Data folder.
Wave_Animations: contains wave animations created from the model data for the project area. Files are provided in a Microsoft PowerPoint (2010) file and as stand-alone animation files.
Wave_Time_History_modified: contains modified wave time history data; both wave elevation/height and velocity data for simulated gauge stations within the model. The time history data are provided in multiple formats: as a .pdf book of charts, within an Excel (.xlsx) file, and as ascii text files within the appropriate Grid folders. Time series data were extracted from tsunami model runs at 10 second time steps. The text files are the original files provided by Joseph Zhang from the computer model. The .pdf book of charts was created for ease in viewing the data. The Excel files were created as an intermediate step between the model output text files and the creation of the charts. This "modified" data folder contains only the Excel and .pdf books that were the result of processes performed by DOGAMI GIS Analysts.
Reference_Files: contains reference files that may help the user understand and use the data better. These files include Evacuation Brochure Index polygons shapefile, Tsunami Inundation Scenarios for Oregon (Open-File Report O-13-19) report (.pdf), Tsunami Inundation Map (TIM) Index polygons shapefile, Tsunami Data Grid Seams shapefile, and a Tsunami Project Areas and Grids Index Map (.pdf). Please see the metadata for information about the GIS shapefiles provided.
