Last week several doctoral students of the doctoral programme were busy in the HOAL in repairing and maintaining equipment in the research catchment. Casings of data and power supply cables were checked for damages, which e.g. sometimes can occur by animals and were repaired. Also weathered logger…

Yesterday Patrick Hogan and Borbala Szeles have been in the field to calibrate the Eddy covariance devices. Borbala will now gradually take over the responsibilty for the weather station installations with the support of Patrick.

For the calibration a dew point generator was used. This device is…

Currently an infiltrometer measurement campaign is operated by Tommaso Picciafuoco (guest student from University of Perugia, Italy) at the HOAL catchment. With several Double Ring infiltrometer sets and one Csiro infiltrometer device he is determining the saturaded hydraulic conductivity on a grass…

Some days ago atmospheric scientist Patrick Hogan was in the field, supported by Matthias Oismüller, to maintain some of the weather station devices.

The present weather station (which is measuring raindrop distribution) and the mobile eddy covariance systems (evaporation) were checked and prepared…

Recently at the eight new ground water monitoring gauges, which were installed in Sepember 2016, diver sensors have been installed to permanently monitor the ground water level at these gauges.

The eight gauges are located at different representing spots in the catchment and were drilled from 15…

Currently the HOAL is still covered by a snow layer of 10cm or partly even more. In the next days warmer temperatures are predicted so we expect the melt of the snow and a rise of the discharge at the stream or even slight overland flow on the fields.

Therefore Matthias Oismüller and Markus…

Today Markus Oismüller was collecting the precipitation deposit samples from the HOAL weather station. The first try yesterday to 'just' drive down with the 4WD car to the spot of the weather station failed due to too high snow on the road.

Luckily a neighbouring farmer could help to get out the…

Matthias Oismüller, Rasmi Silasari and Isabella Pfeil (new doctoral student of the Vienna Doctoral Programme on Water Resource Systems, watch her profile here) are currently installing the temporal soil net again at the HOAL fields.

The soil net sensors had to be removed from the fields for a short…

In the last days Patrick Hogan (DK WRS), Matthias Oismüller (TU Wien) and Claire Brenner (BOKU Wien) installed soil flux sensors, radiation sensors and an eddy covariance station at the border of two fields with different land use. On one field maize is growing, the other field is currently bare…

Due to a cooperation between the Institute for Water Quality, Resources and Waste Management of TU Wien (IWAG) and the Environment Agency Austria (Umweltbundesamt) colleagues from TU Wien installed today a deposit collector at the HOAL weather station site.

The goal of this project, where Ottavia…
