The aim of the project is to bring together researchers from many complementary domains around a common objective. The research unit created for this purpose (DFG-Forschungsgruppe) aims to develop a new framework for the implementation of hydrological models for the purpose of a better representation of the surface and subsurface architecture of meso-scale watersheds (from 10 to 200 km2). To reach this objective, the project is striving to bring together:
This project’s key objective is to develop a model and mathematical framework that, in the end, will allow for better integration of this information into the model’s identification process, while also consequently improving the dialogue between experimentalists and modellers. All of the works will be carried out in the Attert basin, which has been equipped with measurement apparatus since 2003.
The experimental hydrology work was extended to the entire expanse of the Attert catchment area. Considerable measurement equipment was installed in order to measure the various components of the water cycle (e.g. meteorological stations, liquid level reporters, automatic samplers). As a supplement to these experimental hydrology works, a flexible development framework of concepts for hydrological models was developed. It will be used for interpreting the various components of the rain-flow conversion seen in the field. In view of the exceptional quantity of data generated during the project, a dedicated database was set up. This tool uses the CUASHI (Consortium of Universities for the Advancement of Hydrologic Science) hydrological information system that was specifically developed for the management and sharing of hydrological data.
