Resumee Preliminary Study Leitha

A conversation with Mag. Johann Nesweda, Federal State Lower Austria.

What was the focus of the preliminary study?

The focus of the preliminary study was on the collection, analysis and evaluation of existing relevant data. Regarding flood risk management, the focus was on the aspects of discharge investigation and sediment balance; regarding river development, we were mainly interested in hydromorphology, residual flow situations and the biological quality elements; on the topic of planning framework conditions, we looked at what data already existed with regard to water rights, nature conservation, spatial planning and recreational function.

What are the important findings of the preliminary study? What does this mean for the GE-RM?

After the available data had been compiled and evaluated, the data situation was assessed. If there were deficits, a working concept was drawn up for the next step in the GE-RM process – the supplementary inventory.

Summarising, the preliminary study showed that the existing data situation is good in many areas and that additional data only needs to be collected in individual areas for the further planning process.

What were the challenges and highlights?

One challenge of the GE-RM Leitha is certainly that two Federal States – Lower Austria and Burgenland – are involved, which requires more coordination. For this reason, an external project coordinator was appointed from the beginning, also for the preliminary study phase, to ensure cross-border coordination.

Outlook and Timeplan

In mid-June 2020, based on the results of the preliminary study, the inventory, guiding principles and concept of measures – we call it the main study – were put out to tender and awarded. A kick-off meeting with the external project coordinator and the GE-RM main study team has taken place. The inventory to collect the missing data will begin in the summer of 2020. In any case, the GE-RM study should be completed by autumn 2021.

“The preliminary study has shown that the existing data situation is good over wide areas and only in individual technical fields additional data needs to be collected for the further planning process.”
