 # Reinout's case study/proposal
 
-Note: Reinout, who writes this, hasn't heard anything about specific case studies, apart from "the Ahrtal floods in 2021". In order to write down the proposal contained in the `README.md` in this project, I had to come up with some case study as an example in order to figure out our (=Nelen & Schuurmans) project setup. This is just *my* example: perhaps useful as input for the project.

-- I'm interested in the project because of the *context broker*: it connects me to the *semantic web* from my PhD years.
-- I'm very interested in railways in the Eifel region (of which the Ahrtal is a part). See [this youtube video](https://www.youtube.com/watch?v=EvDXScsPGvs) as an illustration.
-- I've actually studied the 2021 floods in the Ahrtal quite a lot.

 ## 3: detection of critical locations
 
 Based on the flood prediction, a prediction of critical locations could be made. I know N&S can do that, but perhaps a project partner can too. Flooding of railways, bridges or important roads ("Bundesstraße") or medical facilities comes to mind.
 
-Such critical locations could really benefit of real-time drone imagery and monitoring. In reality, the upper reaches of the Ahr valley were crying for help while the authorities in the lower reaches were suspecting them of panick-making. Their own official downstream measurement equipment never went beyond a certain worrying level as the equipment literally stopped reporting after being ripped out by the flood...

-Note that there are historical precedents for this situation! In 1910, one century earlier, a similar flood occurred. At that time, construction activities to extend the railway line in preparation of the first world war resulted in lots of driftwood that clogged many bridges in a similar destructive manner.
