A set of time series has been investigated which spans more than 50 years of groundwater head measurements throughout the Netherlands.
The relation between the groundwater head and precipitation and evaporation has been established using linear transfer noise modeling. This has been done for each entire series and for parts. The latter to detect base level changes and other groundwater regime changes.
The relation between the groundwater head and precipitation and evaporation has been established using linear transfer noise modeling. This has been done for each entire series and for parts. The latter to detect base level changes and other groundwater regime changes.
In addition, trends in the other components of the groundwater heads have been investigated as well as possible non linearities in the groundwater response.
The link is explored between the trends and regime changes from the time series models on one hand and anthropogenic (land use) changes and climate change on the other hand.
