Internal Wave Simulation

Mon, 08/27/2018 - 12:31am — Tyler
Hello everyone, I am a new CEW2 user and am trying to determine if this simulation scenario is appropriate. I've essentially inherited a calibrated CEW2 model of river-reservoir system from an elder research student who was primarily focused on water temperature. We collected some in-situ data which suggests small-scale internal wave activity which is primarily influenced by the hydropeaking of the dam. I'd like to try and model this phenomenon, and given that I have a base-line model of the system already I was wondering if CEW2 can represent the physical mechanisms well enough for analysis of the in-situ data. In general the site favors a 2-D laterally averaged model, but I haven't found much research online analyzing internal waves with CEW2. Is there any reason this wouldn't work? Any suggestions or advice would be much appreciated. Thanks.

W2 should be able to simulate internal waves. As an example, see our Detroit Lake temp. animation*, scrolling forward to May, when you can see that the stratification is affected by internal waves. Though, if your in-situ data is "small-scale", the utility of the model might depend on how that scale relates to the model layer height and general grid scaling. Though, of course, you could always modify the grid to a finer scale. *https://or.water.usgs.gov/projs_dir/or00311/detroit_lake/detroit_lake_temp_2003.html
