@terrypacker I know this thread is a year old but we are now trying to set up a display to capture this event and I have been searching the forum when I saw your entry. I am not sure if you are still looking for cases but I have one.
We have set up a monitor and display that is checking rainfall levels, reservoir levels, and discharge flow rates into rivers and drainage systems for a flood prevention service. Obviously this is a hot topic these days and companies are spending a lot of time to gather, monitor and log this information. Our system is just the online portion of this system and the company will use the information as a kiosk style display so that the main office can see what is happening across the various points at a glance.
We have set up 2 sets of high alarms, the first an amber warning and the second a red critical warning for the levels and flow rates. We have also set up the Rate Of Change event detector for the flow rates that will alert on an increasing rate of change and a decreasing rate of change so the users will alerted to the flood potentials.
On test the system works well and thankfully since the system went live we have not had an event yet. I like the Rate of Change Event Detector for this type of application as it can give an early indication of the flood potential before the actual reservoir levels have reached the warning levels.
Cheers
