AGU 2018 Poster: Building Web Applications to Support the Execution of U.S. National Water Model at Watershed Scales

The US National Water Model (NWM) is a mesoscale hydrologic model that provides streamflow forecasts and other valuable hydrologic information for the continental United States. Since its release at the National Water Center (NWC) in 2016, the NWM has garnered broad attention and great interest across the hydrology science community. Several projects are underway with the goal of delivering this advanced modeling technique and its data to researchers and end users in the community.
As one of the flagship projects, the CUAHSI HydroShare project is working toward providing a complete solution for storing, managing and sharing NWM data. So far, it has set up the largest open-access data archive for the NWM outputs and has developed several different open-source tools and web applications assisting users with data access.
However, there is a growing demand in the hydrologic sciences community for the capability to run a local instance of NWM at regional watersheds to support research applications such as cross-model comparison, historical data analysis and etc.
In this paper, we present ongoing work to develop web applications on top of HydroShare for collecting NWM input data to support model execution at smaller scale watersheds.

美国国家水文模型（NWM）是一款中尺度水文模型，为美国大陆提供河流流量预测及其他宝贵的水文信息。自2016年在国家水文中心（NWC）发布以来，NWM受到了水文科学界的广泛关注和极大兴趣。目前，已有多个项目正在进行中，旨在将这一先进的建模技术和其数据提供给社区的研究人员和终端用户。作为一项标志性项目，CUAHSI HydroShare项目致力于提供存储、管理和共享NWM数据的完整解决方案。迄今为止，该项目已建立了NWM输出的最大开放式数据存档，并开发了多种开源工具和Web应用程序，以协助用户进行数据访问。然而，水文科学界对在区域流域运行NWM本地实例的需求日益增长，以支持跨模型比较、历史数据分析等研究应用。在本文中，我们介绍了在HydroShare之上开发Web应用程序的持续工作，以收集NWM输入数据，以支持较小规模流域中的模型执行。
