Thematic Module 2
Monitoring of water quantity, quality and ecological status

The highly continental climate with long and cold winters accompanied with the corresponding ice cover of the surface waters and distinct diurnal temperature amplitudes in summer result in great challenges for aquatic communities. During evolution, many species have adapted their life cycles to these extreme conditions. Most of the rivers showing much less anthropogenic influence as comparable water bodies in Central Europe. However, there is an increasing stress resulting from the rapid economic development during the last 20 years and a rapid population growth which both lead to increased water demand.

The increase of population and their livestock in rural areas harbours a high risk of increased matter import into the aquatic environment and microbiological contamination. The latter aspect is particularly relevant since surface water is used as a drinking water source for people and animals.

In this thematic module the monitoring approaches and results of project phases I and II will be implemented at Mongolian authorities. One of the main tasks is the further development of a web-based geo-data base that allows a consistent management of environmental data. Additionally, trainings and workshops will be conducted in order to implement a comprehensive environmental monitoring on the long-run.

A network of three water quality monitoring stations was set up in the upper, middle and down reaches of Kharaa river. Data are automatically transferred to an online database.
