Another seiche occurred on Lake Erie December 23-25, 2022.  Here is an animated plot using the NOAA PORTS data.
Revisiting the river flow profile plot from an earlier post, the video below loops each day's flow profile for the Delaware River in 2019.  Data is from USGS gages processed using R and Windows Live Movie Maker.
Our second fish tank experiment with the Flir One was to insert a foam rubber divider and fill each half of the tank with hot and cold water.
My son and I played around with an old fish tank, some tap water, and a Flir One thermal imaging attachment for a smart phone.  Here is part one.

My prior post on animated flow in the Delaware River contained the last work I performed on my previous lap top just before it gave up the ghost.  When a colleague asked me to share it, I was distressed to realize that the script was lost.  I decided to recreate the script from scratch and to fix one the limitations of the older version by making it easily transportable to other river systems.  Specifically, all the USGS gage numbers, drainage areas, and river miles are contained in a .csv file.  To apply the new script to the different river, I just need to populate the .csv with local information.  I'm glad I did that, since there were several high flow events at other rivers that I wanted to inspect using this script.

Above is the Neuse River after Hurricane Florence.  I also applied this to the Susquehanna River and the Schuylkill River.

My colleague and I recently published a technical note in the Journal of the American Water Resources Association (JAWRA) on automating a hydrodynamic model of the Delaware Estuary.
This video shows the progression of flooding in the non-tidal Delaware River River during Hurricane Irene and Tropical Storm Lee.
