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（US National Water Model, NWM）是一款中尺度水文模型，可为美国本土提供河道流量预报及其他高价值水文信息。该模型于2016年在美国国家水文中心（National Water Center, NWC）发布以来，已在水文科学学界获得广泛关注与浓厚兴趣。
目前已有多个项目正在推进，旨在将这一先进建模技术及其数据开放给学界的研究人员与终端用户。作为旗舰项目之一，CUAHSI HydroShare项目正着力打造一套完整的NWM数据存储、管理与共享解决方案。截至目前，该项目已建成规模最大的NWM输出数据开放获取档案库，并开发了多款开源工具与网页应用，助力用户便捷获取相关数据。
然而，水文科学学界对在区域流域内部署本地NWM实例的需求日益增长，以支撑跨模型对比、历史数据分析等各类研究应用。
本文介绍了一项正在开展的研究工作：基于HydroShare开发网页应用，用于收集NWM输入数据，以支持小尺度流域的模型运行。
