Animal haulage, again. On the upper Loire sand barges float down on the current from a dredger, then with a finely-judged tweak, alter course for the lock giving access to a branch of the Lateral Canal. For years the tweak was delivered by Rene Guichard, who tapped on the towline with his stick, then tapped again for his charges to stop pulling. It all worked like magic. When Rene passed away a tractor had to be used instead and it was never quite the same.

Interesting, I have several recorded accounts of English boatmen saying if a pair of donkeys were used they always had to be side by side. If not the front one would keep stopping to look for the one behind.

Yesterday (18Jan) in 2017

spacer.pngOn Boxing Day 2015, water from the River Ouse and River Foss in York combined to flood 627 homes and more than 300 people were evacuated. The flood barrier on the River Foss was raised because the pumping station capacity was lower than the flow arriving at the pumps from the River Foss. There was much public criticism as the flood surrounded a raised flood barrier, which was seen as not doing its job. 

The Foss Barrier picture is from 12Jan2012. It was constructed in 1989,  and the moveable barrier is a large turn-and-lift gate, which when in flood-defence mode, isolates the Foss from the Ouse, stopping Ouse water from flowing upstream into the Foss.  The optimum level of water in the Foss is maintained by pumping its water around the (closed) barrier, directly into the Ouse with eight high volume pumps, combined capacity of just over 30m3/s (30 tonnes per second) .

The modelled solution was to double the pump capacity and show how and if the new system would work with the increased flow both into and out of the pumps. The pumps were first modelled on the computer, which enabled many scenarios to be tried, then the preferred solution was modelled in the physical laboratory in Yeadon to prove the principle.

The picture above was a visit to Yeadon by the Chartered Institution of Water and Environmental Management (CIWEM)

Royal Docks London. Early start 5.45am so that the group of narrowboats could have passed the City Airport runways before any morning flights. Something to do with large lumps of moving metal upsetting their radar. (Compare aerial view here)
