Fig. 5: Impact of factors on GWS recovery in Beijing for 2006‒2018.
From: South-to-North Water Diversion stabilizing Beijing’s groundwater levels
GWS anomalies and decomposed time series using the STL (Seasonal and Trend decomposition using Loess) decomposition method from in situ measurements and GWS simulations from the CWatM-MODFLOW model during 2006‒2018 under three scenarios (S1‒S3). Shown also are linear GWD changing rates for each decomposed time series, with the significance of these rates listed at the 0.05 level (referring to the “Methods” section).
