EXPLANATION OF FILES INCLUDED WITH THIS PUBLICATION

from the readme.txt file--

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 momentum flux, minimum flow depth, and maximum vorticity, over the course of the entire simulation, for specific locations. The data provided are for all seven tsunami scenarios (SM, M, L, XL, XXL, AK64, and AKMax) published by DOGAMI.

Please read the Open-File Report O-13-19, Tsunami Inundation Scenarios for Oregon report (provided as part of this publication in the Reference_Files folder) for a brief technical summary of the tsunami mapping approach. For detailed information on how the Cascadia Subduction Zone (CSZ) tsunami scenarios were developed and tested against geological, geophysical, and paleoseismological observational data, please see DOGAMI Special Paper 43, Simulating tsunami inundation at Bandon, Coos County, Oregon, using hypothetical Cascadia and Alaska earthquake scenarios, Witter and others (2011).

The Coos Bay Project Area extends from approximately 8 miles south of Coos Bay to approximately 5 miles north of Haynes Inlet in Coos County. This project area does not cover the entire Coos County extent. The Bandon Project Area publication contains data adjacent and to the south of this project area. The Central Coast Project Area publication contains data adjacent and to the north of this project area.

The Coos Bay Project Area is made up of two computational grids: one for Cascadia sources and one for Gulf of Alaska sources. The two grids differ only in refinement in earthquake sources. (Tsunami modeling that occurred later in the 4-year project used different computational grid methodologies.) For purposes of this data release, the output data are organized by the entire project area as one set of model output files (vs. two computational grids).

ProjectArea_Data: contains the raw model output data in ascii format (.dat files). These data include information on maximum momentum flux, minimum flow depth, and maximum vorticity data.

Reference_Files: contains reference files that may help the user understand and use the data better:
