Elbe-DSS 是一个基于计算机的系统，用于易北河流域德国部分的综合流域管理。模拟模型用于评估重新造林、农业实践改变或废水处理厂的效率等措施的效率，以实现管理目标。 MONERIS 和 GREAT-ER 已集成到 Elbe-DSS 中，以评估养分和污染物负荷。 MONERIS 在约 1000 km(2) 的子流域范围内计算来自分散源和点源的养分输入。 GREAT-ER 是一种用于点源排放暴露评估的工具，并考虑污水处理厂的命运以及河流中的降解和运输。两种模型都做出长期预测，但它们的操作空间尺度不同。 GREAT-ER 将整个河网划分为小段，通过路由算法将这些小段连接起来。这些段使用累积流长度分布耦合到 MONERIS。连接两个模型可以将 MONERIS 计算出的扩散养分排放量和 GREAT-ER 的点源排放量分配到河网，并计算进一步的消除和运输过程。我们在一项研究中举例说明了 DSS，该研究评估了不同的重新造林和侵蚀控制措施对河网中磷酸盐负荷和浓度的影响。 (c) 2005 Elsevier Ltd. 保留所有权利。
The Elbe-DSS is a computer based system for integrated river basin management of the German part of River Elbe basin. Simulation models are used to assess the efficiency of measures such as reforestation, changes of agricultural practices or the efficiency of wastewater treatment plants for achieving management targets. MONERIS and GREAT-ER are integrated into the Elbe-DSS to assess nutrient and pollutant loads. MONERIS calculates nutrient inputs from diffuse and point sources on a sub-catchment scale of about 1000 km(2). GREAT-ER is a tool for exposure assessment of point source emissions and considers fate in sewage treatment plants as well as degradation and transport in rivers. Both models make long-term predictions, but their spatial scales of operations differ. GREAT-ER divides the whole river network into small segments that are linked through a routing algorithm. The segments are coupled to MONERIS using accumulated flow length distribution. Linking the two models allows to distribute diffuse nutrient emissions calculated from MONERIS and point source emissions from GREAT-ER to the river network, where further elimination and transport processes are calculated. We exemplify the DSS in a study assessing the effects of different reforestation and erosion control measures on phosphate loads and concentrations in the river network. (c) 2005 Elsevier Ltd.
