This proposal outlines relevant steps in the development of a model coupling strategy designed to bridge the gap between process based denitrification modeling and landscape scale transport. The overall aim is to design a catchment modeling framework in a way to facilitate the general coupling of other models as well, for example to simulate pesticide fate, erosion, or eutrophication processes. Three goals are identified that will be worked on during this project proposal: (1) Prior to communicating the new model structure we want to discuss the model design and its practicability with key experts. (2) The numerical methods for the integration of the subsurface system has to be checked to increase the computational efficiency and the numerical stability of the model. (3) The model has to be verified against measured discharge data, water path way information and mean residence times. The work will be conducted in a cooperation visit to Oregon State University, Corvallis, Oregon, US.

该提案概述了相关步骤的模型耦合策略的发展，旨在弥合基于过程的反硝化建模和景观尺度传输之间的差距差距。总体目标是设计一个流域建模框架，以促进其他模型的一般耦合，例如模拟农药的命运，侵蚀或富营养化过程。本项目建议书确定了三个目标：（1）在交流新模型结构之前，我们希望与主要专家讨论模型设计及其实用性。(2)为了提高计算效率和模型的数值稳定性，必须对地下系统积分的数值方法进行检查。(3)该模型必须根据实测流量数据、水路径信息和平均停留时间进行验证。这项工作将在对美国俄勒冈州科瓦利斯的俄勒冈州州立大学的合作访问中进行。
