Storing water in high quality and quantity is the key to sustainable water management. Smart-SWS, with its consistent storage of runoff peaks and wild runoff in existing aquifers and the delayed and long-term provision of the stored water in dry periods, goes well beyond flood protection during extreme events and links flood and drought management. The time scale of hydrological extreme events is strikingly asymmetrical: short-term heavy rainfall and flood events (days) contrast with long-term dry periods (weeks to months). The conflicting requirements of extremely efficient infiltration and at the same time strongly delayed discharge force technical interventions in infiltration, conditioning of the water to ensure groundwater quality and regulation of the outflow into the receiving water. To ensure safe operation, measurement concepts and sensor networks are being developed that combine stationary sensor technology with mobile data collection using Unmanned Aerial Vehicles.<\/p>

The goal is the technical implementation of a decentralised storage concept in existing aquifers that is capable of storing one or more flood peaks and releasing them to the receiving water with a very significant time delay or holding them for higher-value use.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
