Requirements for Online Utilities and Lessons: Docker Logo

Docker (Community) = > v.17.12 (currently we use
Web browser (Google Chrome recommended) for accessing the Jupyter notebooks/Jupyter Lab. 
Note: Each machine is different. You will need to alternate your Docker settings such as CPUs, Memory, and Disk Space allocations according to your machine to optimize runtime. If you find a bug or other technical issue please log it on the github issues site

Lessons walk you through model compiliation and various model simulations with different configurations.

Training Workshop: The Community WRF-Hydro Modeling System

June 2-5, 2020 || Boulder, CO - CANCELLED 

Due to developments associated with COVID-19, CUAHSI and NCAR have decided to cancel the in-person WRF-Hydro Training that was scheduled for 2-5 June 2020 in Boulder, CO.

If you have already registered, CUAHSI will be in contact directly. The registration fee will be refunded.

NCAR and CUAHSI are considering rescheduling this workshop. Thank you for your patience as we consider options moving forward.


2nd European Fully Coupled Atmospheric-Hydrological Modeling and WRF-Hydro® Users Workshop

Join us at the University of Calabria, Rende (Cosenza, Italy), June 14-18, 2020 for the 2nd European Fully Coupled Atmospheric-Hydrological Modeling and WRF-Hydro® Users Workshop!

This Workshop is an opportunity to meet and exchange ideas and experiences with coupled atmospheric-hydrological modelers from research groups around the world to address the challenge of improving hydrometeorological forecasts and the need for accurate projections of hydrological impacts due to climate change.
We invite abstracts focusing on the complex interactions between surface water, groundwater, and regional climate as well as those that focus on the development of fully-coupled hydrometeorological prediction systems for flood and water resources prediction. Presentations on novel coupled modeling systems that bridge spatial scales through dynamic regridding or upscaling/downscaling methodologies are also welcome, as are comparative studies between one-way and fully-coupled modeling systems, combined dynamical-statistical approaches, data assimilation in coupled models, field studies with measurements supporting multi-variable validation of coupled modeling systems.

The latter part of the workshop (from June 17 to 19) will be dedicated to the Community WRF-Hydro® modeling system that was released by the National Center for Atmospheric Research (NCAR) in 2013, by means of 2.5 days hands-on tutorial. There are 20 spots available for this hands-on tutorial. 

WRF-Hydro® Tutorial Description:
This 2.5-day workshop will provide graduate students, early-career scientists, and professionals with formal instruction on the structure and application of the WRF-Hydro system in a coupled instance. It will offer hands-on experience in setting up and running the system for several different research and prediction applications.
Topics covered during the workshop may include:
  • Conceptualization and structure of the WRF-Hydro system
  • Description of physics components and options within WRF-Hydro
  • Model input data preparation
  • Hands-on model configuration and execution of an example test case
  • Hands-on experimental model simulations and comparisons with a prepared example test case
  • Overview of model calibration
  • Open discussion on class participant interests and applications
Tutorial Requirements:
Participants of the hands-on tutorial are required to bring their own laptop computer with:
  • SSH and X-server capability
  • Google Chrome web browser
  • (Optional) ArcGIS 10.7 with Spatial Analyst extension activated and 64GB background geoprocessing - this will be for creating the hydrologic routing input files

The deadline for abstract submission is April 30, 2021.
Early registration fees expire on April 30, 2021.
