Article Synopsis
- Researchers assessed reactive nitrogen losses in Austria under four climate change scenarios from 2041-2070 using two nutrient models (MONERIS and SWAT).
- Both models showed similar findings regarding inorganic nitrogen loads in water, with minor differences, while highlighting the importance of factors like fertilizer type and climate conditions on nitrogen losses.
- The study's results emphasize the significance of understanding nitrogen transport pathways in the context of climate change for effective policy-making and resource management.
Article Synopsis
- * The study analyzes regional N budgets, focusing on agricultural production, consumption, and N emissions across Austria, using material flow analysis to identify losses and nitrogen use efficiencies (NUE).
- * Findings show significant regional disparities: alpine regions have low N inputs and inefficient NUE, while lowland areas exhibit higher N efficiency but face groundwater nitrate issues, reflecting the complex interplay between production systems and environmental factors.
Understanding the role of soil moisture and other controls in runoff generation is important for predicting runoff across scales. This paper aims to identify the degree of non-linearity of the relationship between event peak runoff and potential controls for different runoff generation mechanisms in a small agricultural catchment. The study is set in the 66 ha Hydrological Open Air Laboratory, Austria, where discharge was measured at the catchment outlet and for 11 sub-catchments or hillslopes with different runoff generation mechanisms.

However, they are often impacted by pathogen discharges via wastewater treatment plants (WWTP) and combined sewer overflows (CSO). To date, accurate predictions of the effects of future changes and pollution control measures on the microbiological water quality of rivers considering safe drinking water production are hindered due to the uncertainty of the pathogen source and transport variables.

The study area is the Hydrological Open Air Laboratory, Lower Austria. Event runoff coefficient (Rc), recession time constant (Tc) and peak discharge (Qp) are estimated from hourly discharge and precipitation data for 298 events in the period 2013-2015.
