目前正在开发一个分布式水文模型，用于模拟莫塞尔河流域的径流过程。该研究项目有几个目标：开发一个水文模型，以便进行短期和长期模拟，并应用于真实的时间洪水预报，具体说明土地使用变化的影响，查明潜在气候变化的水文影响。该模型以模块化的方式构建;对于水平衡的每个组成部分，定义了某些模块并将其组合成主计算机程序。该系统以一个地理信息系统为基础，该系统是根据数字地形模型、大地卫星图像和数字化地图建立的，所有这些都具有30 x30米的空间分辨率。为了减少计算工作量，具有相同水文特性的网格单元被集中到“水文相似单元”中。
A distributed hydrological model for simulation of the rainfall-runoff process in the Mosel River catchment is under development. The research project has several objectives: development of a hydrological model allowing short-term and long-term simulation and application for real time flood forecasting, specification of the impact of landuse changes and identification of the hydrological effects of potential climatic changes. The model is structured in a modular way; for every component of the water balance certain modules are defined and combined into a main computer program. It is based on a geographic information system derived from a digital terrain model, on Landsat satellite imagery and on digitized maps, all having a spatial resolution of 30x30 m. In order to achieve a reduction in computational effort grid elements having equal hydrological characteristics are lumped together into 'hydrologically similar units'.
