How directing water flows in the landscape could support groundwater and surface water streams

Researchers at the Leibniz Centre for Agricultural Landscape Research have investigated how water from streams can be stored in the aquifer during wet periods. Using an area in the lower Spree catchment in Brandenburg as an example, the team used a computer model to show that naturally occurring small basins in the landscape could absorb excess stream water, allowing it to seep slowly into the ground and subsequently stabilize groundwater and connected surface water bodies. In the calculations, the groundwater level rose locally by up to 2 meters (6.6 feet). Water flow in connected streams could be increased by up to 15%. The study was published in the Journal of Hydrology: Regional Studies.
