Hydrological Open Air Laboratory (HOAL) Petzenkirchen

The HOAL Petzenkirchen is situated within walking distance of BAW-IKT. Measurements within this small headwater catchment, which is drained by a small brook of about 600 m started already in 1945. Presently, hundreds of different sensors are installed within HOAL to permanently monitor the hydrological cycle and the transport of soluble and solid matter.

Short Description:

Since 2009, monitoring within the HOAL Petzenkirchen is carried out together with the Technical University Vienna (Institute for Institute of Hydraulic Engineering and Water Resources Management, Prof. Günter Blöschl). This headwater catchment of about 66 ha contains hundreds of sensors to monitor data such as precipitation, temperature, wind, water flow (surface runoff, drainage, spring flow), sediment load, water chemistry and soil moisture. Many of these parameters are measured with highest spatial and temporal resolution. In addition, manual sampling and field campaigns take place on a regular basis. Analytics are mainly carried out within the premises of BAW-IKT, particular analytical procedures such stable isotopes are carried out together with cooperation partners. It is the dedicated aim of the HOAL to monitor, measure and balance water flow and nutrient as well as matter transport with high resolution. Results will also be used for modelling purposes to allow drawing conclusions about past, present and future developments for the complex interaction between agriculture and water management.
