Application of the Artificial Intelligence (AI) methods, especially the neural networks for water related studies is expanding lately, due to its advantages such as being less subjected to he constraints of the physical considerations and quick delivery of feasible and cost-effective responses. Primary stage results of the research are presented in two separate examples.The first example is the runoff modelling for the case of Yellowstone River, USA at the outlet of a high-altitude lake using neural networks, in which the influence of melting ice and snow cover is carefully considered. A wavelet transform is used for smoothening the input signal for the neural network model in order to improve the accuracy and prevent the inconsistency of neural network solutions. A morphological evolution study along cross-shore profiles at the Kiel Bay, Baltic Sea coast using ANN provides the second case. Data preprocessing or in this particular case downsampling of bathymetry measurements through a number of cross shore profiles was done by a wavelet transform.The data oriented approaches, such as neural networks often have to deal with the abundant data or noisy observations, which normally require a thorough analysis, preprocessing or downsampling, to enable a satisfactory performance of the models. The above case studies emphasize the importance and necessity of the data analysis and preprocessing.

Web Services represent an emerging model for developing and deploying software applications that promises to fundamentally change not only the way companies build and deploy software, but also how they communicate with their partners and customers. This approach can improve the flexibility and the reach of ecisting ICT infrastructures. An example from river-engineering and inundation management will be given.

The establishment of "virtual laboratories" including application of Internet based project platforms, distributed team work and collaboration methods require new kinds of soft skills, knowledge and experience and a new "technological culture" to be generated just by doing - a task for education, training and profession in Hydro-Informatics. This is a challenge for the European dimension, where in future experts and engineers from different countries with different languages, different mentalities as well as different specialization and professional experience have to collaborate in research, teaching and practice. Training of collaborating in such new environment is the challenge of the courses HydroWeb and HydroEurope which by collaboration of 23 universities world-wide will help to establish common high quality university teaching courses and establish links between students from the involved countries. The students are solving a given environmental engineering task in distributed teams in the Internet. The students acquired in this course experience in interdisciplinary team work, net based project co-ordination and Web based reporting. They strengthened their social competence to collaborate in heterogeneous teams with members of different habits, nationalities, ages, educational backgrounds. The described experiment might be the basis to introduce Web based collaborative engineering in the regular course programme of water-environment related curricula at universities.

Moderne Informations- und Kommunikationstechnologien rücke dabei mehr und mehr in den Vordergrund. Die Entwicklung von Werkzeugen zum Hochwassermanagement, welche Informationen in kürzester Zeit sowohl für Krisenmanager als auch für den einzelnen betroffenen Bürger bereitstellen, waren ein Schwerpunkt des europäischen Forschungsprojektes OSIRIS (Operational Solutions fort he Management of Inundation Risks in the Information Society). In Deutschland wurden speziell für Frankfurt (Oder) Web Anwendungen entwickelt, welche Dienste und Informationen zum Hochwassermanagement für "jedermann" anbieten. Beispielhaft werden hier die Vorhersage- und Warndienste näher betrachtet.
