Dearest Klevur Science Bods ..the Makers Of My Awe...

As A sheepy I of course am propositioned so many times every day that I need to employ a secretary and a few lookalike stand ins !...so..when a couple of young filly’s propositioned me to join them for a sesh I was naturally thrilled !

Ewe can imagine my surprise when I realised that the seiche in question was not what I thought but the study of a Tidal Movement in a lake..

Look...here's a lake.

A Lake earlier today.


Nice eh ?..being delivered next Tuesday..

Anyway..it seems that a tidal movement of water in a lake is called a Seche ?...what I'd like  to know is how does one get a tidal movement in a lake ?..what happens when the tidal movement hits the other side ?..and why is it called a seiche ? (sound french)

ewe see....it's like this...I just simply do not know !..me wants to know....and ewe can tell me !

Hugs and shmishes

I didn't know Crater Lake in Oregon was for sale. Was it on E-bay? I wish I'd known, because I would likely have put in a couple of bids myself.

If you don't mind me asking, what did you give them for it?

When they discovered it was me they gave it to me as long as I serviced some broody ewes...which is nice !

Umm... were you planning on keeping it indoors, once it's been delivered?  It's just that it's a volcanic caldera and that future eruptions are quite likely?  Could make a bit of a mess.

Did you also get the Old Man of the Lake, thrown in as part of the deal too?

Well yes, I was planning on keeping it as a water feature in the dining room.....after all..looking at the picture it's ony a about 4 inches across ! []

That old man in the lake though is fascintating....how come it has not decomposed or rotted away after over a 100 years !

Apparently a seiche isn't necessarily tidal - it is a resonance in a lake. A bit like if you make waves in a bath at the right speed those waves get larger and larger until the floor gets wet, and you get shouted at.

According to wikipedia
http://en.wikipedia.org/wiki/Seiche

They can be driven by wind, or small earthquakes, They will have a much longer period than other waves in a lake, and so in a big lake they may appear like tides. Apparently in Lake Eire they can get up to 5m high with a period of about 16 hours.

At last...some info !!  []


Wooo.....a period of 16 hours !...now that is slow. I gather this makes the occurrence quite rare indeed. Thanks Dave....ewe should do this kind of thing for a living ewe know......ewe never know...there may even be a radio show in this somewhere !!  []
