Project desription

The basin associations Wupperverband and WVER are self-governing, non-profit, statutory bodies, subject to North Rhine-Westphalia (Germany) state law. The members of the associations include cities, municipalities and counties located in the basin, companies, such as paper-producing enterprises.

The associations run their reservoir systems to provide domestic water, flood protection for 1 million people and operate the dams to augment river flow during dry spells. The downstream part of the Wupperverband system is one of the most densely populated areas in Europe and uncontrolled floods would cause tremendous damages. Low flow augmentation was the root for setting up the WVER reservoir system. Stable flow conditions enable the production of a wide variety of enterprises, firstly aforementioned paper-industry. Additionally, it ensures existence of wetlands and native river reaches.

The objective of the early warning systems was to enhance disaster risk management. Both systems require forecasts of precipitation to increase lead time for warning procedures and to adapt release rules accordingly.

The Wupperverband runs a precipitation-runoff and reservoir operation model based on Talsim-NG under the platform of FEWS (Deltares) whereas the WVER uses Talsim-NG in combination with FEWS (Deltares) as preferred solution for the operation control centre at the headquarter, but web-based SYDRO Services on-site at the dam sites.

The river basins comprise 12 dams with a total catchment area of 2800 km².
