Streams are among the ecosystems particularly affected by climate change. Long periods of drought (2015, 2016 and 2018) are causing problems in the nutrient and oxygen balance due to extremely low discharges, up to the formation of completely oxygen-free zones in the hyporheic interstitial. Conversely, heavy precipitation leads to nutrients and soil particles entering soils in rivers, often with negative consequences for all those organisms that rely on an oxygenated hyporheic interstitial.
In this project we aim at studying the temporal dynamics of the hyporheic exchange and redox processes of the iron (and nitrogen) cycle at the interface between groundwater and surface water at different hydrological conditions. The project is integrated into the Bavarian Research Network "aquaklif" studying the effect of climate stressore on freshwater ecology
Methoden: We will work both at the field and laboratory scale and use a combination of state-of-the-art spectroscopic and microscopic techniques in the lab and in-situ montoring tools for field studies.
