Model Code Name:
Seasonality Trend Decomposition of Groundwater hydrographs by STL and time series analysis
Description:
The STL (Seasonal Trend by LOESS) method is used to decompose groundwater level time series. The different components are then analysed using time series clustering and correlation analysis
Purpose:
Statistical analysis of groundwater levels
Type:
Time series analysis
