Flanders Hydraulics Research is a research centre of the Flemish Government. The centre provides consultancy services dealing with hydraulics, hydrology and nautical aspects to national and international public or private organisations. Within Flanders Hydraulics Research the Hydrological Information Centre (HIC) is a research group which provides scientific support for water level management on navigable waterways in Flanders. To achieve this, the HIC cooperates actively with the actual managers of these waterways and with other institutions involved in ground water, surface water and sediments. An efficient functioning of the HIC requires powerful tools to load, store and validate data and to make them accessible for all users. For these purposes an application named HYDRA was developed. This article focuses on the setup, the use and the planned evolution of the application.
