Great Whernside resurgences.

[adam]

Talking of water temperature and infrared drone flights, I recently met someone who is planning to do just that on a 2 km stretch of the Upper Ribble this summer. The aim is to look at the size and dynamics of cool water plumes produced by groundwater inputs which are useful refuges for fish during hot weather. I imagine that the resurgences in Ribblesdale are fairly well known so its unlikely to throw up any surprises but I'm looking forward to seeing the results nonetheless. If/when this technology becomes affordable, it could be a very efficient way of resurgence hunting.

Would it not be best to do this either in the dead of winter or the height of summer when the water temperature difference is most noticable?

I'm guessing Big changes will be noticeable at any time of year, "fine tuning" may be best left for Winter/summer?

I think that was grahams's idea:

Thanks for all your help and suggestions. All I need now is a heatwave. I'll post the results later this year.

Thermal imaging cameras can be bought for about ?200 upwards. There's no doubt that using one of these, particularly with a drone, would be a great idea but I value my marriage (and my nuts) so wellies and a thermometer will have to do.

If you could post a link, I'd like to see the results when the come available.

How interesting...
Like the River Wharfe, so also Upper Ribblesdale still holds some surprises.
Our group are exploring a previously unknown (to cave explorers) Resurgence. That shows promise for the exploration of the Upper Ribblesdale master cave.....
Can not reveal much at the moment as exploration is proceeding, but it's exciting and goes to show that just as cavers think an area is well searched, that gems are still waiting to be discovered by determined explorers.

Regarding Low Mill where the resurgence came out above the river ,fed a water wheel
then dropped into the river.Not sure if that excellent Gological map fully explains that.
So how about some clever observant people a long time ago realised that a lower and upper rising were linked
and had the lower rising sealed to increase the flow to the upper one.
That would have benefited the waterwheel out put greatly . :-\
