Adaptive Decision Support System (ADSS) for the Integration of Storm Water Source Control into Sustainable Urban Water Management Strategies

Participating Countries: Czech Republic, Denmark, France, Germany, Greece, Netherlands, Sweden, United Kingdom

Stormwater source control is perceived today as an efficient solution to resolve flooding and pollution problems connected to urban stormwater. It is a key issue for sustainable development in the urban context. However, implementing the best solution remains difficult because the range range of possible measures is vast and individual needs have to be defined. DayWater aims at understanding and integrating these issues in a coherent manner and proposes an adaptive decision support system (ADSS) for the decision makers.

Scientific Approach

The main objective is to develop a tool which can be used by stakeholders in urban storm water management. As the decisions are made within various space and time scales (topography and dynamic nature of urban development) the tool has to be adaptive. The development of an adaptive decision support system (ADSS) provides a synthesis of components organised and tested in European urban areas.

Innovative Objectives of DayWater

All the above mentioned items will ultimately lead to:

Participation of end-users

Scientific partners and end-users will work closely together in order to incorporate all suitable practical advice based on experience and respecting users' needs. To maintain this interaction numerous seminars are scheduled. There is also a constant web-based exchange between urban hydrology partners and the end-user. Recursive interactions with the end-users are organised throughout the project. The end-user group contains 14 members and will increase to around 50.

Contribution to 5th European Framework Programme

DayWater project contributes to the key action "sustainable management and quality of water" by supplying decision makers with support tools. The best tools have to be identified in order to obtain the best solution in a given context for the control of the impact of urban storm water flow and pollution.

It is known that a considerable amount of funds will be invested in the management of stormwater in urban areas in the forthcoming years. Both peak flows and environmental quality have to be controlled. The ADSS will assist the identification of the most sustainable and cost-effective solutions for a range of urban situations. End-users play an active role in field testing, therefore the core end-user group will be extended during the project, enabling the dissemination of DayWater products on a larger scale within Europe. The DayWater project deals with the availability and use of technological progress for the benefit of society. Significant efforts are put into the analysis of how technological information can be used in decision making processes.

At the end of the project all European stakeholders will have access to the ADSS, a sum of state-of-the-art knowledge, decision support tools, methods and data. They will be able to introduce the most attractive elements to their decision making process, thus applying the best techniques. This means optimising the investment costs of the water management and minimising the risks.

CityNet Cluster

DayWater belongs to the CityNet project cluster of six individual research and development projects (2001-2005) which focus on the aspects of integrated urban water management (water supply, sewage, drainage) including their urban/rural interfaces (raw water sources, receiving waters, groundwater).

Main Events

A major aim is to communicate with parties outside the consortium, such as other relevant European projects dealing with integrated urban water management (CityNet Cluster). The preparation of publications, newsletters, an external web site and of course international and regional conferences for the consortium and the end-user group members will be the basis for intense interaction between summer 2003 and summer 2005.

A final event was the International ADSS Conference held in Paris December 2005.
