Shallow groundwater dynamics in the Pampas: climate, landscape and crop choice effects

A study of the western Pampas from 2008 to 2013 found that while topography determines absolute water table position and crop choice can partially modulate seasonal fluctuations, inter-annual groundwater dynamics are predominantly driven by climate variability.

• Climate variability is the primary driver of water table fluctuations at the inter-annual scale, and current crop rotations cannot substantially control these long-term shifts.
• Crop choice influences groundwater levels at an intra-annual scale, specifically where wheat-soybean rotations mitigate the spring rises and summer drops observed in maize and soybean single crops, thereby reducing spring flooding risk.
• Topography affects the absolute position of the water table—with depths ranging from -0.2 to 1.8 m in the lowest positions and 1.8 to 4.4 m in the highest—but it does not influence relative changes in the water table.
