我们开发了一个新的大规模水文和水资源模型，社区水模型（CWatM），它可以模拟水文全球和区域在不同的分辨率从30弧分到30弧秒，每天的时间步长。CWatM是Python编程环境中的开源，具有模块化结构。它使用netCDF 4文件格式的全球免费数据，以紧凑的方式进行阅读、存储和数据生成。CWatM包括一般的地表水和地下水水文过程，但也考虑到人类活动，如用水和水库调节，通过计算水需求，用水和回流。水库和湖泊包括在模型方案中。CWatM用于部门间影响模型相互比较项目的框架，该项目比较全球模型的产出。灵活的模型结构允许与水文经济和水质模型进行动态互动，以评估和评价水管理备选方案。此外，CWatM的新奇在于它结合了最先进的水文建模，模块化编程，在线用户手册和自动源代码文档，不同空间分辨率的全球和区域评估，以及潜在的社区来添加，更改和扩展开源项目。CWatM还努力建立一个社区学习环境，能够自由使用开源水文模型和灵活的耦合可能性，其他部门的模型，如能源和农业。
We develop a new large-scale hydrological and water resources model, the Community Water Model (CWatM), which can simulate hydrology both globally and regionally at different resolutions from 30 arcmin to 30 arcsec at daily time steps. CWatM is open source in the Python programming environment and has a modular structure. It uses global, freely available data in the netCDF4 file format for reading, storage, and production of data in a compact way. CWatM includes general surface and groundwater hydrological processes but also takes into account human activities, such as water use and reservoir regulation, by calculating water demands, water use, and return flows. Reservoirs and lakes are included in the model scheme. CWatM is used in the framework of the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP), which compares global model outputs. The flexible model structure allows for dynamic interaction with hydro-economic and water quality models for the assessment and evaluation of water management options. Furthermore, the novelty of CWatM is its combination of state-of-the-art hydrological modeling, modular programming, an online user manual and automatic source code documentation, global and regional assessments at different spatial resolutions, and a potential community to add to, change, and expand the open-source project. CWatM also strives to build a community learning environment which is able to freely use an open-source hydrological model and flexible coupling possibilities to other sectoral models, such as energy and agriculture.
