Re: [claw-users] Question about Storm Surge Gauge Results

[Kyle Mandli]

More than likely the gauges are not in the water so it by default the gauges plot the height of the topography.  The newer storm surge gauge plotting will plot a red line if the gauge is dry rather than plot the topography if you are interested in that.  You can find the newer code at

https://github.com/clawpack/geoclaw/blob/3303883f46572c58130d161986b8a87a57ca7816/examples/storm-surge/ike/setplot.py#L153

although I think you may need to update to the development version of geoclaw to get the `gauge_surface` and `gauge_dry_regions` functions.  Alternatively you can copy their implementations from

https://github.com/clawpack/geoclaw/blob/3303883f46572c58130d161986b8a87a57ca7816/src/python/geoclaw/surge/plot.py#L94

Preventing this is another question.  You can check to ensure that the gauges are accurately placed (sometimes the precision of the reported gauge locations are not enough and some checking is required).  It can also be a matter that the area around the gauge did not get refined enough.  Sometime this requires putting in a region that is right around a gauge to ensure that that area is refined sufficiently to put the gauge in the water.

Hello everyone, 

I am conducting storm surge simulations and have increased the AMR level, resulting in the last level of the AMR the final topography resolution and grid cell resolution is a value like 100 meters. However, I noticed that in some gauges, the storm surge height plot shows a constant value(This is only about gauges, the 2d simulation works well), while in others, the results appear reasonable. Are there any potential adjustments or considerations that I will be able to solve?

Thank you for the guide in advance,

Mobina

Thank you so much, Kyle.
