And of course Lathkill Head Cave and Dowell Resurgence  in Derbyshire

Been around Derbyshire for a loong time and never heard of flood pulses coming out from either of these locations, has anyone on here any experience of one? (Or, for that matter any other similar locations in the Peak

From my own experience Terry..... In the late sixties I was in a team down in the intestines of Lathkill Head Cave when we were chased out by rising waters and again a few years later a pulse coming through the Dowel Resurgence squeezes made for an exciting exit.... Both pulses came through on dry days...it had been raining the previous day in the Dowel catchment area.

Nor should we forget that Ashton predicted the presence of vadose passage between the base of Rowten Pot and Keld Head...

An artificial flood pulse was used by the YGS as early as 1879 to confirm a flood connection between Tarn Sinks and Malham Cove. The flood pulse took 85 minutes to reach Aire Head, but 130 minutes to emerge from the Cove which is less than half the distance. Presumable the delay in arrival at  Maham Cove is due to the water having to back up from the start of the phreas before being able spill over into a conduit which emerges at the base.

Langcliffe (or anyone else?) - I don't suppose you could quote the reference for that 1879 Malham hydrological exercise could you? It's very relevant to something I'm working on currently. Thanks.

D A Burell 1899

p7 of: The Underground Waters of North-West Yorkshire. Part I. The Sources of the River Aire
Proceedings of the Yorkshire Geological and Polytechnic Society, v. 14:1-44

In 1879 Mr. Walter Morrison, the late Mr. Thomas Tate,
of Leeds, and other members of the Yorkshire Geological and
Polytechnic Society,* made certain experiments with the result
that they concluded that Malham Cove and the springs at Aire
Head were both connected with the Malham Tarn water-sinks.
They further concluded that the Smelt Mill water-sinks in the
Streets on Malham Moor were not connected with Malham Cove,
and the outlet was not discovered.

Also, maybe, if you havnt already got access to it, which could be of interest is;

Thanks, both to Richard & Martin!

I'm slightly confused however; Martin - who was the author of the source you kindly quoted?

Also, Richard, do you know the full reference for "D A Burrell 1899"?

All I need is a single reference to the late 19th C flood pulse tests done by opening the Tarn sluice.

Any chance of clarifying this?  Thanks.

J.H.Howarth was the author of Section I, Introduction, from which I quoted. There is also a Section II, Engineering Report, by C. W. Fennell and  J.A.Bean on gauging at various sites in 1899...

DA Burell at the reference I quoted above

 

[Martin Laverty]

The full 1879 reference is: Thomas Tate (1879) The Source of the River Aire, Proceedings of the Yorkshire Geological and Polytechnic Society N.S., Vol VII., pp.177-186

The experiments were carried out over 4 days in May and involved taking air and water temperatures, chemical analyses, opening the sluices at Malham Tarn, thrusting a sack of chaff into the swallow hole at Streets Smelt Mills, putting bran into the Tarn watersinks, and an attempt to stain the water at the Smelt Mills with magenta (dye). The chaff, bran, and dye were not seen again but the flow, chemistry, and temperature reading were successful.

Martin - I've only just noticed your most recent contribution above - thank you!
