Project objective

An unpolluted stream possesses a high self-purification capacity due to a diversified streambed as well as due to bacteria, fungi and algae. Land use and flood control measures, however, have led to the fact that many streams have been channelled in the last few decades. This led to an acceleration of the water transport, which in turn led to a decrease in the self-purification capacity. If a greater amount of nutrients from the surrounding areas also gets into the stream (e.g. from agriculture and settlements), the water and sediment quality will deteriorate.

This project gets to the bottom of the interaction between pollution and water management and works out suggestions for the management of polluted streams in intensively utilised areas.

How to participate?

School classes will get a manual and log sheets for the recording of data, taking of water samples, water chemistry analyses and, if desired, data analysis. They will submit the data to the institute electronically by means of an Excel data sheet developed by the Water Cluster Lunz.

What happens to the contributions of citizen scientists?

First of all the data will be checked for plausibility and completeness and then entered into a database. By analysing the data the researchers will get an overview of the sediment quality of the examined streams. If a sufficient amount of evaluable data is available, it is intended to publish it.

Prizes and winners

The entries will be ranked by completeness, plausibility and number of data sets. Moreover, the stretches of stream examined and the locations where the samples were taken are taken into account.

The winners of the first prize will get € 1,000.--, those coming in second place will get € 750.-- and those coming in third place will get € 500.--.
