Leave the locks full

Published: Thursday, 07 June 2018

I HAVE been suggesting for many years that where practical locks should be left full of water, writes Jimmy Lockwood.

Thanks to closures in the recent past I suspect Marple locks have been unused for lengthy periods and I guess left empty.

Ease the lock walls inwards

Ground water will have attempted to enter the vacant space—that’s what water does—and in so doing eased the lock walls inwards.

Remember your school science? What was needed was ‘an equal and opposite force’ to oppose this movement. There wasn’t one but if the locks had been filled there would have been!

Is anybody going to fill the rest of the flight whilst craft are prohibited from using it? Sadly I doubt CaRT even understand the logic let alone the laws of motion!
