Experience the account of the historic Ellicot floods by NPR 

 Many staff here at NCAR work on forecasting and researching such catastrophes with the purpose of saving lives and property. This account provides the human element behind the purpose of our work. 

WRF-Hydro is part of the OTREC field Campaign! OTREC Logo

What hapens to all the precipitation after it rains?  And how can our model simulations be imporved by adding observational precipitation data?  We will be teaching a WRF-Hydro modeling system course in conjunction with the OTREC field campaign on the University of Costa Rica campus in San Jose 21-23 August. 

The OTREC field campaign is studying the deep convection in the ITCZ over Costa Rica. The NSF-sponsored Organization of Tropical East Pacific Convection (OTREC) field campaign began on  August 5th and is in full swing until September 30th, 2019. There are mulitple components to this campaign to gather measurements from both air and land.  Our involvement includes Dave Gochis providing a portable radiosonde unit expertise and 10 surface meteorological stations as well as 3 instructors to teach a WRF-Hydro Course to participants from multiple Central American countries from both academic and government entities.

WRF-Hydro v5.0 Used in AT&T Climate Resiliency Study

Read the White Paper: Road to Climate Resiliency: The AT&T Story

"The WRF-Hydro® (Version 5) was employed to simulate the entire hydrological cycle in watersheds across a region. The model used a range of inputs—from future climate variables (precipitation, temperature, humidity, wind, solar radiation) to topography and vegetation—to inform a physics-based model.With projected precipitation and other climate parameters as input across the region, WRF-Hydro® computes the extent of inland flooding that can be expected, as well as other characteristics such as depth of surface water accumulation, stream flow and flood duration."

 

"WRF-Hydro® (Version 5) simulated the water cycle to project the depth and extent of inland flooding for historical and mid-21st century timeframes. These mid-century results project increased surface water accumulations over 5% in inland and coastal regions in the southeastern U.S. under a business-as-usual emission scenario during warmer seasons (spring, summer, and fall). Extreme flood events are also projected to increase across the four priority states. For example, by mid-century, a 50-year flood event will produce flood waters up to 10 feet deep across inland and coastal areas of southeastern Georgia."

Tropical Island Hydrology Training

Virtual Workshop: Current Topics in Tropical Island Hydrology- Water Hazard & Resource Prediction

As a part of the RAL Diversity Fund Award the interactive virtual workshop Current Topics in Tropical Island Hydrology: Water Hazard & Resource Prediction & the WRF-Hydro Modeling System drew over 200 attendees from 44 different countries.countries represented at tropical island hydrology workshop This event developed significant scientific capacity and initiated a community mindset across different branches of Tropical Island Hydrology from research to operations to public outreach resulting in a community of practitioners who will strive to reduce societies vulnerability to tropical island flooding events. 

Watch the video below to:

  • Hear from seasoned experts on current research topics such as tropical rainfall, tropical hydrologic forecasting, and island processes

  • Understand a technical overview of WRF-Hydro® modeling system & discuss the National Water Model Hawaii implementation

  • Engage in a demonstration of a severe flash flood event case study over Oahu with the WRF-Hydro Modeling System using cutting edge technological cloud-based distance learning modules

Cloud-based Distance Learning Capabilities in Hydrometeorological Forecasting for Tropical Islands

Project Summary

Focused hydrometeorological forecast guidance is currently under-utilized in a vast majority of tropical island
nations for which water hazard prediction and water resource provisioning are essential. With funding from the Research Applications Laboratory (RAL) Diversity Fund, we have built cloud-based distance learning modules tailored to the specific and unique hydrometeorological forecasting needs of tropical island nations utilizing the WRF-Hydro® modeling system. 
 
These learning modules will allow graduate students, early-career scientists as well as seasoned scientists and forecasters in the fields of atmospheric and hydrologic science interested in hydrologic forecasting applications for tropical islands the ability to run the WRF-Hydro modeling system with a prepared test case using a laptop, a web browser, and a cloud service provider. By employing cloud-based technology to these learning modules, computational capacity and cost barriers to entry for new model users especially from economically challenged
and disadvantaged communities and institutions will be greatly reduced. These learning modules were created in collaboration with Dr. Yin-Phan Tsang and Yu-Fen Huang from the University of Hawaii, Manoa.
These learning modules utilize a test case created for a representative Tropical Pacific Island (Oahu, Hawai'i) and a flash flood event described below.

Collaborators

Dr. Tsang is an Associate Professor at University of Hawaiʻi at Mānoa, Department of Natural Resources and Environmental Management  and Director of the Tsang Stream Lab which  investigates surface flow processes and their implications in fluvial ecosystems. Dr.Tsang was also recently awarded the NSF EPSCoR RII Track-4 fellowship for Building the Next Generation Meteo-Hydrological Model for Hawaii, using WRF-Hydro, which aims to establish collaboration between the university and national research laboratory to address water issues that contribute to both economic and security in Hawaii state. Yu-Fen Huang is a Ph.D. student at the Universtiy of Hawaii, in the Tsang Stream Lab. Her current research focuses on how peak streamflow (i.e. flash flood in Hawaii) changes under changing climate in Hawaii.
 
Disclaimer: These training modules are currently in Beta and demonstration status and will be available for public use in the near future. One must request access via our online contact form and specify the intent of use. 

Study Area: Island of Oahu, Hawaii

About the Event 11-14 October, 2008

Widespread flooding occurred across the island of Oahu, Hawaii. The official (NWS-HFO) information page describes the storm: "High Winds and Flooding Rains"
  • The December 2008 major storm event reportedly produced very large rainfall amounts over short periods of time (estimated 7.2 – 8.1 inches over a 12-hour period). Heavy winds at Waianae boat harbor and extensive flooding (up to chest high) in Wainanae were reported.
  • Flooding along Kaupe Road: A local farmer reports $30,000 worth of damage to farm equipment when chest-deep flood waters inundated the property.
  • Sewage Overflow: 675,000 gallons of partially treated waste water flowed into the Kaukonahua Stream from the Schofield Barracks WWTP. An additional 90,000 gallons overflowed from six manholes in Schofield Barracks. Also, 81,000 gallons overflowed from manholes in the Wheeler Army Airfield.
  • Power Outage: HECO reports approximately 14,000 customers without power on Leeward and Windward Oahu coasts.

Community Spotlight

 Marcelo Somos-Valenzuela in front of a lake and in a river measuring streamflowThis Community Spotlight focuses on Dr. Marcelo Somos-Valenzuela. Marcelo is an Assistant Professor at the Universidad De La Frontera with a demonstrated history of working on projects related to adaptation to climate change in diverse regions such as the Himalayas in Nepal, the Cordillera Blanca in Peru, Contiguous United States, and Patagonia in Chile. His areas of expertise are hydro-climatology with an emphasis in field observations and regional modeling, water resource management, social vulnerability and climate change. 
During the 'pandemic' he has taken time to learn how to bake and is, for the most part, enjoying the results of his experiments.  

Below is a Q&A with Marcelo about his background, current research, and experience with using WRF-Hydro®

Understanding how different pieces of a system work and interact in a model provide the opportunity to learn through experimentation.


Q: What initially excited you about modeling as your chosen area of study?
A:
 My general interest has always been the hydrological cycle. So understanding how the different pieces of the system work and interact in a model provide the opportunity to learn through experimentation. Also, I have been fortunate to participate in projects that seek to provide information for adaptation to natural disasters, climate change, and social vulnerability in developing countries as well as the US. Therefore, modeling became an excellent tool for me to explore solutions to different problems in particular, where data is not available.

Q: How did you first come to find out about the WRF-Hydro modeling system?
A:
 It was in the presentation that Dr. Gochis gave in a meeting for the National Flood Interoperability experiment back in 2014. At that time, I was working as a PostDoc with Dr. David Maidment at the University of Texas. Then we used WRF-hydro streamflow results for the NFIE retreat in the water center in Tuscaloosa, Alabama, during summer 2015. So I got to know what the WRF-hydro was about and took the training at NCAR twice to learn how to use it.

Q: What is your current research project focusing on?
A:
 I am working on different projects. The first one explores the impacts of climate change in snow and glaciers in the Chilean Patagonia. The second is a collaboration with a Chinese institution where we seek to understand mudflows' chain of events triggered by hydro climatological events. Then, I am working in a forecast system using WRF-Hydro for streamflow predictions.

Q: What aspects of the WRF-Hydro modeling system made it most suitable for your research/ project needs?
A:
 Since I started learning WRF-hydro, the documentation available and the development of tools have immensely increased, which makes it easier to keep track of the new progress as well as to train students to use it. Also, there is always a new application or improvement that can be used. For example, now I am working with WRF-hydro Glac to simulate glacier hydrology in the Chilean Patagonia.
