Landeshochwasserzentrum Sachsen
The Landeshochwasserzentrum Sachsen (LHWZ) is the Saxony state flood control and coordination centre responsible for flood forecasting, real‑time monitoring and operational warnings in Saxony. Based in Dresden, the centre integrates hydrological data, meteorological forecasts and civil protection procedures to reduce flood risk for urban centres such as Dresden and riverine communities along the Elbe and its tributaries.
The LHWZ's mission is to provide authoritative flood situation awareness, issue timely warnings and support emergency management agencies during high‑water events. It consolidates inputs from the LfULG, the Deutscher Wetterdienst (DWD), the BfG and municipal water authorities to produce river forecasts and operational guidance. Key objectives include protecting life and property, coordinating interagency response, and improving resilience through information sharing with Katastrophenschutz (civil protection) bodies and local governments in Saxony.
The LHWZ is headquartered in a purpose‑equipped operations room in Dresden, colocated with offices and technical facilities for continuous monitoring. The site hosts redundant communication systems, large‑screen situational displays, and access to flood modelling platforms. It maintains direct data links with river gauges on the Elbe and tributaries such as the Mulde and Freiberger Mulde, and with the DWD radar network. The Dresden facility supports 24/7 staffing during flood seasons and is configured to operate with the state emergency framework and local Sächsische Landesdirektion emergency centres.
LHWZ operates an integrated flood monitoring architecture combining automatic telemetry from hydrometric stations, meteorological nowcasts from the DWD, and hydrodynamic models used for short‑ and medium‑range river forecasts. Systems include gauge networks managed by the LfULG, model chains based on the EFAS and national models from the BfG. The centre issues graded warnings and situation reports to municipal authorities, the Landeshochwasserwehr and the public via official channels. It also interfaces with the national BBK (Federal Office of Civil Protection and Disaster Assistance) alert architecture and supports cross‑border data exchange with neighbouring German states and the Czech Republic.
As the state coordination hub, LHWZ convenes operations with the Saxon ministries, municipal emergency services in Dresden, regional water boards, and utility companies (e.g., waterworks and power providers). It provides decision support for reservoir operations, levee management and temporary flood protection measures such as mobile barriers used in Dresden's historic centre. The centre participates in regional flood risk management plans under the EU Floods Directive implementation in Saxony and contributes to risk assessments and contingency planning alongside academic partners like the Technische Universität Dresden and research institutes including the Helmholtz Centre for Environmental Research.
LHWZ supports applied research on hydrology and flood forecasting by collaborating with universities and research centres in Dresden, notably the Technische Universität Dresden and the Leibniz Institute. It organises regular training exercises for civil protection personnel, flood forecasting workshops for hydrologists, and joint drills with municipal fire brigades and police. Public outreach activities include publishing seasonal flood outlooks, explanatory materials on flood preparedness for Dresden neighbourhoods, and participation in community resilience events. The centre contributes data to academic studies and operational improvements such as enhanced telemetry and ensemble forecasting.
The Landeshochwasserzentrum Sachsen was established following severe flood events that highlighted the need for centralised forecasting and coordination; its formalisation accelerated after the Elbe flood of 2002, which heavily affected Dresden and surrounding regions. Since then the LHWZ has been central to responses during major episodes including the 2013 Central European floods and subsequent high‑water events on the Elbe and Mulde. In these operations the centre coordinated warnings, supported tactical reservoir releases, and advised on the deployment of temporary flood defences and evacuation measures. Post‑2002 and post‑2013 reforms led to investments in telemetry, modelling capacity and interagency protocols that improved lead times and situational awareness for Dresden and the wider Saxony region.
