dc.description.abstract
Soil erosion and phosphorus (P) runoff pose major challenges to agricultural
sustainability and water quality management. This study, conducted in the
Hydrological Open-Air Laboratory (HOAL) in Petzenkirchen, Lower Austria,
aims to identify agricultural fields within the catchment that are particularly
susceptible to erosion and to predict future sediment and P loss under
various scenarios. The HOAL, a small, agricultural headwater catchment (60
ha), provides an ideal setting for this detailed investigation due to its diverse
land use practices and comprehensive historical data. Moreover, the HOAL

represents a typical agricultural landscape for the Austrian Alpine foothills. This
characteristic allows for the transfer of research findings to numerous other
regions in Austria.
Our primary objective is to identify fields highly susceptible to erosion and
predict future sediment and P loss under erosive precipitation events. The
study employs an extensive dataset spanning from 2010 to 2020, considering
key indicators including soil management practices, fertilizer application rates,
and the frequency and intensity of erosive rainfall events. By analyzing these
indicators, we aim to identify trends and patterns that can help to predict
erosion risk and P loss.
Our methodology aims to integrate field observations with advanced geospatial
and statistical techniques. GIS-based tools will be employed to map erosionprone areas and to correlate these areas with specific land management
practices. Statistical analyses, including regression models, are utilized to
identify the most significant predictors of sediment and P loss. This combination
of techniques are expected to enable the compilation of detailed risk maps that
can be used to inform future land management decisions.
We anticipate that this research will provide valuable insights into the
mechanisms driving soil erosion, sediment yield and P loss to receiving waters
in agricultural landscapes. By identifying high-risk fields, we aim to offer insights
that may help to reduce overall sediment erosion and phosphorus (P) loss,
particularly from those fields that contribute above-average amounts.
Ultimately, this research aims to contribute to the development of strategies that
mitigate sediment and P loss, thereby protecting water quality and promoting
sustainable agriculture. The findings will be of interest to policymakers, farmers,
and environmental scientists seeking to balance agricultural productivity with
environmental stewardship.
