Model Instance Title:
Seasonal trend decomposition and time series analysis of groundwater hydrographs from boreholes in the Eden Valley, Cumbria, UK  
Model Instance Short Name:
Eden boreholes  
The STL decomposition is applied on the groundwater level time series from 18 boreholes in the Permo-Triassic Sandstone in the Eden Valley (UK). This decomposition and further time series analysis are used to identify differences in groundwater behaviour and gain insight into the aquifer physical properties
