I'm curious about this "silting up" described by the article. Was it preventable? Did it happen due to lack of maintenance?

- bombcar 3y agoWikipedia mentions some of it was caused by a bad pipe at a location, but things like this https://www.youtube.com/watch?v=vLZElIYHmAI https://www.youtube.com/watch?v=vLZElIYHmAI indicate that silting would occur naturally, and need to be controlled. It's quite advanced fluid dynamics and study to work out the variables so the flow doesn't drop silt or erode the channel.
- Vecr 3y agoMost natural caves in the UK are either silted up or stained with a natural pigment (peat, etc). Keeping water clear in a tunnel over the course of centuries without replacing the wall linings regularly would probably be hard if there's anywhere the silt or pigment could come from.
