How Wet is Wales Really?

45 minute Lecture|Graham Christian & Gareth Edwards

Abstract

South Wales Caving Club members have been monitoring the rainfall at Penwyllt for over 20 years. This presentation looks at the drivers for starting to monitor the local rainfall and then the more recent monitoring of the stream level in Ogof Ffynnon Ddu One. We look at the equipment used and the problems that cropped up and how they were resolved. The construction details and software used will be discussed along with early results and future developments.
