Surface water pollution with poly- and perfluorinated compounds (PFAS) is a well-recognized problem, but knowledge about contribution of different emission pathways, especially diffuse ones, is very limited. This study investigates the potential of the pathway oriented MoRE model in shedding light on the relevance of different emission pathways on...

The objective of this study was to understand whether spatial differences in runoff generation mechanisms affect the magnitudes of diurnal streamflow fluctuations during low flow periods and which part of the catchment induces the diurnal streamflow signal. The spatiotemporal variability of the streamflow fluctuations observed at 12 locations in th...

Hydrological observatories bear a lot of resemblance to the more traditional research catchment concept, but tend to differ in providing more long-term facilities that transcend the lifetime of individual projects, are more strongly geared towards performing interdisciplinary research, and are often designed as networks to assist in performing coll...

This paper describes the design and characteristics of a new in situ soil moisture network in Austria, developed for the validation of spaceborne and modeled soil moisture products. The carefully chosen design of the network enables upscaling of the point measurements to the scale of a satellite footprint. As a first assessment soil moisture time s...

During rainfall events, the formation of overland flow can occur under the circumstances of saturation excess and/or infiltration excess. These conditions are affected by the soil moisture state which represents the soil water content in micropores and macropores. Macropores act as pathway for the preferential flows and have been widely studied loc...

Evapotranspiration (ET) is an important process between vegetation, soil and the atmosphere and also the link between the surface energy balance and water balance. In the64 ha. HOAL experimental catchment at Petzenkirchen all the parameters of both the water and energy balance are measured. Discharge is measured along the small stream at all the in...

Evaporation is one of the most important processes in describing the land surface- atmosphere interactions since it connects the energy and water balances. Knowledge of the spatial variations in evaporation allows us to better estimate runoff generation processes and crop yields as well as improve regional water balances at a larger scale. However...

We analysed diurnal fluctuations in the stream flow during low flow periods in a 64 ha. experimental catchment in Lower Austria. Detailed discharge measurements in a one minute time interval at different locations along the stream show diurnal fluctuations during low flow situations. The hypothesis is that the diurnal fluctuations are caused by the...

The HOAL Petzenkirchen catchment, located in the prealpine area of Lower Austria extends to about 64 ha. It is intensively hydrologically monitored. To derive information about the distribution of soil properties within this catchment, soil samples were taken at 302 points of the catchment spaced in a regular 50 m grid. Sampling depth for each poin...

Runoff generation mechanisms are important in understanding the spatial and temporal nature of water flows at the catchment scale. Understanding these processes in great detail will enhance the possibility to predict flood events in small and large catchments. This study will focus on rainfall-runoff processes in the Seitengraben Hydrology Open Air...

The Geodynamic Observatory Moxa is located 30 kilometres south of Jena, Thuringia Germany in the narrow valley of the Silberleite. A superconducting gravimeter, which measures changes in the earth's gravit field, is located in the observatory. The gravitational field is not only influenced by tectonic activity, but also by the hydrological situatio...

The fate of nutrients introduced by human activities have significant impacts on both nature and our civilization. Excessive nutrients can contaminate our drinking water as well as promote algae blooms that deplete the surrounding waters of oxygen for aquatic life. It is estimated that agriculture in Austria contributes approximately 60% to the tot...
