Data Management in Flood Prediction

In this paper we present the data management tasks and tools used in a flood prediction application of the CROSSGRID project. The application consists of a computational core a cascade of three simulation stages, a workflow manager, two user interfaces and a data management suite. The project is based on the Grid technology, especially the Globus toolkit 2.4 and 3.2 and the EU DataGrid project. The paper begins with brief introduction to the application, its architecture and used technology. Most of the rest of the paper then describes in detail the various data management problems of the application and their solutions. The paper is concluded with a brief description of planned future work.
