Nitrous oxide (N2O) is a potent greenhouse gas stemming mainly from nitrogen (N)-fertilizer application. It is challenging to quantify N2O emissions from agroecosystems because of the dearth of measured data and high spatial variability of the emissions. The eco-hydrological model SWAT (Soil and Water Assessment Tool) simulates hydrological process...

The prediction and control of river sediment yield (SY) are critical but challenging tasks. Erosion and sediment transfer in river catchments are controlled by different processes, whose relative importance varies in space and time. We thus put forward that SY can be estimated more efficiently by using explicitly the information contained in the si...

Occurrence and concentration of a broad spectrum of micropollutants are investigated in Austrian river catchments, namely polycyclic aromatic hydrocarbons (PAHs), polybrominated diphenyl ethers (PBDEs), organotin compounds, perfluoroalkyl acids (PFAAs) and metals. The parallel analysis across multiple environmental and engineered compartments sheds...
Article
The tremendous increase in resource consumption over the past century and the environmental challenges it entails has spurred discussions for a shift from a linear to a circular resource use. However, to date most resource studies are restricted to one material or a single sector or process. In this work, a coupled material flow analysis taking the...

Phosphorus mining from phosphate rock is associated with economic as well as environmental concerns. Through phosphorus recovery from municipal wastewater, countries could decrease their dependency on the global phosphate rock market, however, conceivably leading to an increase in environmental impacts from fertilizer production. In this work 18 ph...
Article
There is increasing evidence of water temperature being a key controlling factor of stream ecosystem metabolism. Although the focus of research currently lies on carbon emissions from fluvial networks and their potential role as positive climate feedback, it is also important to estimate the risk of eutrophication streams will be exposed to in the...
Article
In a resource efficient economy, entropy generation must be kept low and high-entropy wastes should be transformed into low-entropy recycled products, thus saving natural resources. Based on this idea, statistical entropy analysis (SEA) was put forward as a method to evaluate material flow systems with respect to their ability to concentrate or dil...

Protecting water bodies from eutrophication, ensuring long-term food security and shifting to a circular economy represent compelling objectives to phosphorus management strategies. This study determines how and to which extent the management of phosphorus in Austria can be optimized. A detailed national model, obtained for the year 2013 through Ma...
Article
Material Flow Analysis (MFA) studies for a particular substance often exist for several different countries or regions, but share a similar goal and scope. In direct comparisons of such regional resource budgets, the importance of the choices made in establishing an MFA system tends to be disregarded. We identify and quantify the effects of choices...
Article
The validity of material flow analyses (MFAs) depends on the available information base, that is, the quality and quantity of available data. MFA data are cross-disciplinary, can have varying formats and qualities, and originate from heterogeneous sources, such as official statistics, scientific models, or expert estimations. Statistical methods fo...

Phosphorus (P) is one of the key elements that sustain life on earth and that allow achieving the current high levels of food production worldwide. It is a non-renewable resource, without any existing substitute. Because of its current dissipative use by mankind and to its very slow geochemical cycle, this resource is rapidly depleting and it is st...

The lake Neusiedl, in the easternmost part of Austria, is a shallow, slightly alkaline steppe lake. It is an internationally important wetland and refuge for endangered bird species, and a relevant source of economic services in Eastern Austria. A number of studies in the past years have raised concerns over different issues jeopardizing its water quality and on the large knowledge gaps affecting this ecosystem. In particular, the role played by the large reed belt in influencing the water quality of the lake at present is not understood.This project aims to enahnce our understanding of the exchange processes between reed belt and lake and of the role played by the reed belt in ensuring a good water quality of the lake. Through a combination of field measurements, laboratory experiments and modelling, the project will deliver a solid scientific basis for the development of an appropriate management plan, which for the first time will regard the lake and the reed belt as a whole.
Project
Danube Hazard m3c is an international project funded by the Interreg Danube Transnational Programme. It builds on the three elements of water governance (m3: measuring, modelling and management) complemented by c: capacity building. Specifically, the project aims to improve the knowledge and understanding of the status quo of hazardous substances (HS) water pollution in the Danube River Basin, by integrating and harmonizing available existing data of HS concentration levels and by modelling emissions at catchment scale in pilot regions. To bridge critical knowledge gaps and to provide a robust basis for modelling and management, targeted measurement campaigns will be carried out not only in rivers but also in environmental and anthropogenic compartments leading to emissions of HS, such as soils, atmospheric deposition and wastewater treatment plants. A further goal is to enhance the transnational management of HS water pollution, through: i) coordinated prioritization of transnational measures with consideration of territorial needs, pursued through basin-wide emission modelling, assessment of management scenarios and elaboration of recommendations for the Danube River Basin Management Plan and ii) tailor-made training activities and workshops. According to the EU Water Framework Directive, HS pollution is a major water quality issue to be tackled in the Danube River Basin (DRB). This also applies to non-EU Member States, which committed to pursue similar goals within the International Commission for the Protection of the Danube River (ICPDR). Despite a significant risk of failing to achieve such goals, this topic is heavily underrepresented in the current DRB District Management Plan (DRBMP) and national plans, mostly owing to substantial knowledge gaps and to the lack of system understanding as well as institutional capacity regarding HS emissions pathways and effective management options. The project aims to achieve a durable and effective transnational control and reduction of HS water pollution. Danube Hazard m3c is led by the TU Wien and counts on a strong partnership of top experts and stakeholders from universities, national authorities, international organisations, interest groups and environmental agencies.
Project
Fluorescence spectroscopy is a very promising tool for the identification of organic substance fingerprints in water resource systems. It is rapid, sensitive and relatively inexpensive. Knowledge gaps and challenging interpretation of large and complex datasets are currently hindering the full exploitation of its potential. Within this project, we aim to develop and test a novel systemic approach coupled with Bayesian statistical techniques to overcome existing obstacles. We will explore different applications of this tool in different water systems in Austria.
