7 March 2016: This meeting is now fully-subscribed and we can take no more attenders
The British Cave Research Association will hold a field meeting in the Malham area on the 14th and 15th May 2016. The objectives are to provide a practical demonstration of water tracing techniques and to add to knowledge of the karst hydrology of the Malham area. There will be an evening meeting on the 14th to introduce the practical work which will be undertaken on the 15th. This will comprise:
- Release of a flood pulse by opening the sluice on Malham Tarn. Data logging water depth recorders in the stream draining Malham Cove Rising and at the Aire Head Risings will monitor passage of the pulse. It is hoped that the pulse will also be monitored by temperature loggers placed in the phreatic cave behind Malham Cove Rising and at the risings.
- Injection of three separate tracers into sinking streams and installation of passive detectors to detect their passage. Water samples will also be collected for later laboratory analysis.
An evening meeting in Malham Village Hall is planned for talks on relevant subjects and for a discussion about re-forming the BCRA hydrology special interest group. There is plenty of accommodation, at all levels of comfort, in the area for those staying overnight.
For this meeting we need to know in advance approximately how many people are interested so that we can plan the various tasks involved. This first circular is a call for interest and a second circular will follow in due course with more detail of the experiments, accommodation etc. If you are interested to attend please email Graham Proudlove at
g. firstname.lastname@example.org and you will be added to the list of attenders.
The second circular will follow once we have an idea of numbers.
