3D Electrical Resistivity Tomography, Koppl

 

3D electrical resistivity tomography

Heavy rainfall events on water saturated soils activated springs and lead to high surface runoff on a slope in Koppl, Austria. To understand water flows in space and time, we investigated the near surface underground with an Electrical Resistivity Tomography (ERT). The objective of the study is to generate a 3D near-subsurface model with focus on hydrogeological mechanisms of the slope.

Lake Mondsee Phosphorus Emissions

Mondsee Wasser Qualität

The lake Mondsee is struggling with a rather high amount of total phosphorus in its water. Too much phosphorus in the water can have a negative impact on the water quality and can also lead to eutrophication. By using the sensors of the Landscapelab, it is tried to comprehend, how, when and where the phosphorus emissions are being transported into the lake. Once it is known, where and when most of the phosphorus is being transported into lake Mondsee, decisions can be made to prevent further pollution of the lake. The main purpose is the detection of phoshorus emissions into surface water bodies during extreme events. These are 2-4 annually occuring heavy rainfall events and the snow melting period in relation to grassland harvests and manuring times.

Study about the correlation between heavy rainfall events and phosphorus emissions in the Plainfelderbach river

In 2016, the interfacultary department of applied Geoinformatics implemented a study which observes the correlation between heavy rainfall events and the phosphorus emissions into the Plainfelderbach river. The results show a significant increase of the amount of the total phosphorus in the river a few hours after a heavy rainfall event (see poster). It can be said that strong surface runoff, caused by heavy rainfall events, supports the washing out of nutrients into the Plainfelderbach river. But heavy rainfall does not necessarily cause high phosphorus emissions in water bodies. Further data like manuring, vegetation cover, relief and soil data has to be taken into consideration.The Plainfelderbach river collects all the water from the Koppl catchment area und finally leads it into lake Mondsee. The Koppl catchment contains an area of about 6km². It does not only collect the water, but also all the nutrients which are being brought out by the farmers to fertilize their pasture. If there is not enough time for the nutrients to percolate and be absorbed by the soil, rainfall can wash it right down into the river. Hence the nutrient condition of the Plainfelderbach river is of special interest when it comes to detecting the spatial and temporal origin of phosphorus emissions. At the edge of the Koppl catchment, where the Plainfelderbach river leaves the area, a weather station is installed. This station also contains a sensor for detecting phosphorus in water, the Water Insitu Analyzer (WIZ). To gain reasonful information about the phosphorus amount, a flowrate sensor, the Sontek IQ Plus, has been installed in the river to measure the amount of water in time.
