RIBUST
Abstract
The 4-year lead project deals with the potential of river margins and woodland to sustainably reduce the pollution of rivers with nutrients and microbiological faecal inputs under current and future climatic conditions. In the bank area, with the help of field tests, soil analyzes and a model, we will investigate the conditions under which buffer strips guarantee efficient phosphorus and nitrogen retention. Using water and sediment samples from Lower Austrian streams along a land use gradient, we analyze how the presence or absence of waterfront strips and riparian trees influence nutrient storage and release, oxygen consumption and the occurrence of faecal microorganisms in stream sediments. The results also form the basis for a risk assessment of a future deterioration in water quality in the course of climate change. Finally, in controlled laboratory tests with the help of stable isotope analyzes, we investigate whether and how organic material from the bank vegetation can positively influence the long-term binding of phosphorus and nitrogen from the water column.
