2005-2006 Beijing Environment Project II

Aim of the project: The proposed project aimed at improving the air and water quality in Beijing in a sustainable manner by reducing air pollution especially during the cold season and by improving wastewater management at a major urban river system, and by improving the municipal institutions for environmental management. The project supported facilities to reduce emissions by collecting and treating municipal sewage within the river basins. The project was carried out in co-operation with DonauConsult Zottl & Erber ZT-GmbH (DI Dr Seebacher) and DI Michael Mende as well as the Beijing Municipal Planing Commission. Key expert for DWS Hydro-Ökologie (previously Donabaum & Wolfram OEG) was Dr. Karl Donabaum.

2017-2020 EU INTERREG project REBEN (Austria – Hungary)

The INTERREG project REBEN is an Austrian-Hungarian research project under the scientific lead of DWS Hydro-Ecology. Other contractors are the University of Technology in Vienna with the Institute for Water Quality, Resource Management and Waste Management (pollutants) and the Institute of Hydraulic Engineering and Hydraulic Modeling, the TB Schuster (online probes), a team of experts from Hungary (TU Budapest, Univ. Sopron) and mecca Consulting (administrative project management). The aim of the project is to create a water management plan that will help to preserve and maintain good water quality and good ecological and chemical status of the lake in the long term. The investigations include chemical and biological analyses, especially in the reed belt of Lake Neusiedl. The focus lies on the exploration of water exchange and the associated mass transfer processes between reed belt and open water.

2001, 2007, 2013, 2019 Joint Danube Survey

The Joint Danube Survey (JDS) is the largest river expedition of the world and has been carried out since 2001 in 6-years-intervals. Under the lead of the International Commission for the Protection of the Danube River (ICPDR), experts from all 14 countries of the Danube catchment area contribute to this great scientific enterprise. DWS Hydro-Ecology was involved in 2001 and 2007 with algal analyses (as sub-contractor of Univ.Prof. Dr. Martin Dokulil). In 2013, our employee Ulrich Donabaum MSc. participated in several weeks of field work, which led from Germany to the Romanian Danube delta. Our employee Dr. Daša Hlúbiková worked on benthic diatoms in co-operation with the Water Research Institute in Bratislava. In 2019, DWS Hydro-Ecology took the responsibility for the work on the quality elements phytoplankton and phytobenthos for Austria.

Tasks: Field work (2013, 2019), phytoplankton analyses (2001, 2007, 2013, 2019), phytobenthos analyses (2019)

2013-2016 intercalibration of ecological evaluation methods in Bulgaria

The aim of the project was the intercalibration of ecological assessment methods for various biological quality elements (phytoplankton, phytobenthos, macrozoobenthos, fish) in rivers and lakes of Bulgaria. Key experts were provided by DWS Hydro-Ökologie. In cooperation with the Umweltbundesamt and national experts, sampling took place at the Danube,  different lakes, and mediterranean rivers of southern Bulgaria. Based on these outcomes, fit-in reports were compiled for numerous water types, which were subsequently audited by the Joint Research Center in Ispra (Italy) and accepted by the ECOSTAT Group. Thus, the project became a milestone in the implementation of the EU Water Framework Directive in Bulgaria.
