Clear and quick transfer of information is a key factor in modern flood prevention. The eight strong NOAH partnership, led by STOWA, a Dutch organisation, develops a new transnational approach to manage these high water situations around two key objectives. Firstly the partnership will seek to develop and implement a new IT system called FLIWAS which makes innovative use of GIS support systems. Thanks to its modular design FLIWAS combines data from a variety of existing high water prediction systems such as geo-databases, alert-plans, flooding maps and calamity-scenarios. Secondly the partnership will seek to build flood partnerships between water authorities, governmental organisations, general public and other relevant parties involved. The goal of these partnerships is to involve all stakeholders actively on the issues of high water management and by doing so create awareness to the benefits and cost of water to local communities. By setting up a website, circulating newsletters, report and organising a number of workshops, and seminars, the NOAH partnership wants to strengthen the transfer of information between relevant EU funded projects, experts and public institutions, improve the knowledge base and transfer between water management authorities in order to strengthen transnational cooperation on these issues. Achievements: The main outcome of the project is FLIWAS and an international working group which will be installed to support and maintain FLIWAS in the future. FLIWAS gives water managers access to current and reliable information, which can be easily exchanged inside and between organisations. Important and easy accessible documents are: Evaluation report: NOAH, lessons learned, experience gained. Short FLIWAS movie. Presentations shown during NOAH conference (see website
