TethysDash

A powerful dashboard designed to visualize and analyze hydrological data using the National Water Model (NWM) services. At its core, the application integrates an interactive map, time series plots, and statistical summaries to provide comprehensive insights for water resource management.The map component allows users to visualize geographical data, including river reaches and gauge locations, providing a spatial context for hydrological phenomena. The time series feature displays water flow data for each reach and gauge over time, enabling trend analysis and prediction. Meanwhile, the stats section aggregates data from various NWM services, offering key metrics such as flow forecasts, streamflow, and runoff predictions.This application is ideal for professionals in hydrology, researchers, and decision-makers who need a unified tool to assess and predict water conditions based on real-time and historical data. The dashboard features a high-resolution, layered map interface powered by NWM data, enabling users to overlay critical hydrological features such as river networks, streamflow pathways, USGS gauge stations, and flood risk zones. Users can toggle between real-time data (e.g., current streamflow, precipitation anomalies) and forecast models (e.g., 7-day flood projections) while leveraging spatial query tools to isolate specific watersheds or regions. Customizable basemaps (topographic, satellite, or hydrographic) and clickable features provide instant access to metadata, such as reach identifiers, elevation profiles, and historical flood events. Integration with geospatial APIs allows for cross-referencing with external datasets, such as land use patterns or infrastructure vulnerabilities, enhancing situational awareness for disaster preparedness.

一款基于美国国家水文模型（National Water Model, NWM）服务开发的高性能水文数据可视化与分析仪表盘。该应用的核心功能集成了交互式地图、时序折线图与统计摘要模块，可为水资源管理提供全面的分析视角。地图模块支持用户可视化各类地理数据，包括河道河段与水文测站点位，为水文现象提供空间参照背景。时序图表模块可展示各河段与测站的流量随时间变化的数据，助力趋势分析与预测工作。与此同时，统计模块整合来自多类NWM服务的数据集，可输出流量预报、河道流量与径流预测等核心指标。
该应用适配水文领域专业人员、科研人员与决策者使用，可为其提供统一的工具，以基于实时与历史数据评估、预测水文状况。该仪表盘搭载基于NWM数据构建的高分辨率分层地图界面，支持用户叠加显示各类关键水文要素，包括河网、径流路径、美国地质调查局（United States Geological Survey, USGS）测站与洪水风险区。用户可在实时数据（如当前河道流量、降水异常值）与预报模型（如7日洪水预报）之间切换，并可借助空间查询工具筛选特定流域或区域。支持自定义的底图（地形、卫星影像或水文底图）与可点击的要素功能，可让用户快速获取河段标识、高程剖面与历史洪水事件等元数据。通过与地理空间应用程序编程接口（Geospatial Application Programming Interface）集成，该仪表盘可与外部数据集（如土地利用格局或基础设施脆弱性数据）进行交叉比对，提升灾害应急准备的态势感知能力。
