Groundwater level fluctuations

Change in precipitation and temperature will affect groundwater levels. Increased rainfall may lead to increased groundwater levels by up to several tens of centimetres. However, in the south-eastern parts of Sweden groundwater levels are expected to decrease.

The timing for the peak of groundwater recharge varies throughout the country. Groundwater recharge is expected to increase during the winter months, mainly in southern Sweden, due to heavy rainfall caused by higher temperatures.

The water table fluctuates between seasons and is lower during the summer. The time period for the reduced water table during summertime may be extended because of earlier snow melt, higher temperatures and longer summers. This can cause problems for domestic water supplies. However, the water table is likely to remain unchanged over the last few months of the year.
