Clouds and Vegetation Modulate Shallow Groundwater Table Depth

Abstract A 10-yr simulation of shallow groundwater table (GWT) depth over a temperate region in northwestern Europe, using physics-based integrated hydrological model at kilometer scale, exhibits strong seasonal cycle. This is also well captured terms near-surface soil moisture anomalies, terrestrial water storage and GWT anomalies from observations the region. The modeled monthly anomaly statistically significant ( p < 0.05) moderate positive/negative correlation with non-rain- rain-affected incoming solar radiation. vegetation cover produces local control on variability depth. Thus, much simulated cycle could be linked to distribution clouds vegetation. spatiotemporal clouds, partly influenced by Rhine Massif, modulates radiation precipitation Particularly, southwestern northern part Massif divided Valley dipole behavior relatively high (low) fluctuations, associated positive (negative) negative (positive) precipitation.
