WRF-Hydro System

A community-based coupling architecture designed to provide:

1) An extensible multi-scale & multi-physics land-atmosphere modeling capability for conservative, coupled and uncoupled assimilation & prediction of major water cycle components

2) Able to estimate water flow, velocity, and water elevation across spatial and temporal scales

3) A robust framework for land-atmosphere coupling studies

WRF-Hydro Modeling Requirements

Fast access to historical and real-time hydrologic meteorological data, metadata, and geospatial information to support forecasts and analyses

Incorporation of a choice of useful sources and formats

Ingestion of real-time data assimilation products

Hydrologic ingestion of ensemble weather forecasts

A framework designed for flexible calibration

Ideal Data Service Capabilities

Define and implement standard interfaces that handle the heterogeneous nature of the data

In situ surface weather and water budget observations, hydrometric observations, and observations through surveys and networks (e.g.: snow, soil moisture, CoCoRaHS)

Water management observations (e.g.: reservoir storage and release, diversions and consumptive-use). Able to generate numerical weather prediction models based on analysis and forecasts

Able to handle and display geospatial information (e.g.: digital elevation models, land-use and land-cover data, hydrographic and bathymetric data, climatology data)

Conclusions

WRF-hydro requires integration with data services in all stages including before, during, and after program runs

Data users must be continually engaged in identifying new applications of the outputs and the technology to deliver data products

In the first phase, the priority should be focused on generation of model inputs and tools for evaluation of results

Future phases can integrate additional resources and technology to fully leverage WRF-Hydro data products with partners and internal users
