Description: Das beantragte Projekt COLABIS zielt auf Entwurf und Entwicklung einer webbasierten Plattform, die die Entwicklung von urbanen Frühwarnsystemen ermöglicht und erleichtert, mit speziellem Fokus auf der Kombination von Umweltdaten, Simulations- und Crowdsourcing-Daten, sowie amtlichen und historischen Daten. Im Fokus der geplanten Arbeiten steht die Untersuchung kleinräumig auftretender Naturgefahren wie Starkregen, Überflutung und deren kaskadierenden Effekte auf urbane Abwasser- und Straßenverkehrsnetze. Durch die Kombination und Fusion von Daten aus den verschiedensten Quellen soll hierfür ein aktuelles Lagebild als Mehrwert für die Entscheidungsunterstützung generiert werden.

Title: FW II: COLABIS; Collaborative early warning and information systems for urban infrastructures; project: Data processing and fusion, monitoring and simulation for collaborative early warning and information systems for urban sewage and transport infrastructure - GEOTECHNOLOGIES special programme
Description: COLABIS will design and implement a Web platform that enables and eases the development of urban early warning systems, specifically focusing on information fusion derived from sensors, crowdsourcing, geosimulations, as well as administrative and historical data. The project focusses on local heavy rain, flooding and cascading events affecting urban water and sewage infrastructures but also traffic infrastructures. Pilot applications serve as proof-of-concepts and help to develop best practices. To support decision makers with timely and value added information, input data from various sources need to be combined. This data fusion comprises data retrieval, enhancement, harmonization, similarity measures, matching, conflict detection and resolving. The consistency and reliability of results essentially relies on the underlying data quality, which varies over the different data sources. Therefore, quality metrics will play a major role in COLABIS. The city of Dresden will be the projects pilot area. Findings from the BMBF-funded project REGKLAM indicate an increasing risk of local heavy rain events in the Dresden area, especially during summer seasons. These heavy rain events paired with previous dry seasons are expected to extremely stress the Dresden sewer system and provoke serious surcharges and local floods with cascading effects on the urban environment and the urban infrastructure. In this context COLABIS will develop a decision support platform for environmental agencies and sewage management companies to - better monitor, model and predict combined wastewater quantities, - better assess its pollution levels during heavy and moderate rainfall events, and - support the related decisions which water to retain, to discharge or treat right away. The monitoring will be supported by modern sensor technology and crowdsourced data. The potential of the newly developed approaches to assess water pollutant levels will get evaluated using simulation-based techniques and data about historical events. For pilot use cases, the Stadtentwässerung Dresden GmbH - one of the COLABIS stakeholders - represents the local sewage management company. Environmental agencies are represented by the Saxon State Office for Environment, Agriculture and Geology. In Dresden, as in most German cities, combined sewer systems are in use, which mix sewage and stormwater to combined wastewater. In the event of heavy rains the capacities of the urban sewage plants are often insufficient to treat the total combined wastewater influx. In this case, to protect the sewage plant from overloading, water will also be discharged as diluted, but untreated sewage (e.g. into the river Elbe in Dresden) after the combined water storage volumes are exhausted (cf. figure below). This concept is known as combined sewer overflow (CSO). (abridged text)
