Lagoon Creek Topography files

zip file with files needed to run the test problem¶

This zip file was updated 8/29/26.

The zip file found at:

https://depts.washington.edu/ptha/CopesHubTsunamis/LagoonCreek/files/LagoonCreek_topofiles.zip

contains three topography DEMs at different resolutions that can be used for this modeling problem, or you can use whatever topography files you have available or need for your software. But to get reasonable agreement with posted results, you will probably need similar resolutions to the files provided.

The zip files contains:¶

etopo30sec.asc¶

30 arcsecond etopo 2022 data, with extent = [-138, -121, 37, 52]

LagoonCreek1s.asc¶

1" data from Coastal Relief Model Volume 7, with extent = [-124.3, -124., 41.5, 41.8]
Source: https://www.ngdc.noaa.gov/thredds/dodsC/crm/cudem/crm_vol7_2025.nc

Updated 8/29/26 to use the new 2025 version of CRM volume 7.

LagoonCreek13s.asc¶

1/3" data from the 2010 Regional DEM, with extent = [-124.12, -124.087, 41.578, 41.608]
Vertical datum: MHW

Jupyter notebook used to construct this data¶

The notebook is in the github repository, in topo/LagoonCreekTopo.ipynb. Here is a rendered version.

Topography extents and gauge locations¶

The green rectangles below show the extents of the 1" and 1/3" topo and the location of 2 offshore synthetic gauges (#100 at roughly 100 m depth, and #40 at roughly 40 m depth).

The zoomed view below shows the 1/3" topo extent and the location of 3 onshore gauges #1, 2, 3.

Sample gauge output for one event are shown in Results for BL13M.

Gauge locations¶

If you want to put synthetic gauges at the same locations as shown in the plots below for comparison, the coordinates are:
