Welcome to the Hydrometeorology and Remote Sensing (HyDROS) Laboratory

The HyDROS laboratory is a proud part of the University of Oklahoma (OU). We are located in the National Weather Center (NWC), Norman, Oklahoma. The HyDROS Lab is associated with the Advanced Radar Research Center (ARRC), Water Technology for Emerging Regions Center (WaTER), and the School of Civil Engineering & Environmental Science (CEES). The HyDROS Lab is a transdisciplinary research unit with synergy at the interface of remote sensing technology, water, weather, and climate. Scales of interest for modeling and prediction include the local, state, regional and global scale.

NASA SERVIR CREST/EF5 Hydrological Modeling Capacity Building Workshops in Kenya and Uganda

Floods have been affecting people in Eastern and Sothern Africa Region through losses of lives and properties. Countries affected by flooding hazards have underdeveloped national meteorological and hydrologic services. The best way to reduce and mitigate these hazards encountered by the communities is through improved prediction of these events. Timely hazard communication, and hydrological forecasting helps to reducing the harmful impacts of floods and associated water-related hazards in the Eastern and Southern African Region. The University of Oklahoma (OU) and NASA Applied Sciences Program’s SERVIR Mission lead efforts to build capacity for monitoring, forecasting, and communicating flood hazards in such developing regions: Advanced Hydrological Modeling and Application Workshops in Nairobi, Kenya and Kampala, Uganda November 18-22, 2019.

The capacity building workshops has used the OU and NASA jointly developed CREST and EF5 hydrological model framework for the SERVIR program. The OU HyDROS group has developed the Regionalized Ensemble Flash Flood Forecasting framework (EF5) for operation over the six countries of Eastern Africa since 2016.

The OU-AST and NASA SERVIR project aspires to support developing countries to mitigate water and water-related disasters through conducting hydrological modeling works using Earth observation satellites and geospatial technologies. The overarching goal of this project is to develop and implement an operational flood forecasting system to mitigate water and water-related disaster and conduct prediction and alerting communication using the Amazon Simple Notification System (Amazon SNS).   

The workshops involve regionalized EF5 hydrological modeling applications and introductions to hydrological concepts, GIS techniques, hydrological remote sensing concepts including rainfall and PET, manual calibration, automatic calibration, interpreting and using model output, DEM practice, calibration practice, Inundation modeling, and multiple gauges analysis. The EF5 model was installed and practiced by the workshop participants so that they can understand how GIS software can be used to help hydrological analysis. The regionalized EF5 hydrological model applications were also covered during the workshop through developing a flash flood threshold using global model and satellite forcings to push alerting notification to potentially save life and properties. The regionalized EF5 hydrological modeling flooding event alerting communication was linked with the Amazon SNS to push notification to RCMRD and end-users through disseminating text and e-mail messages. The workshop helped users and stakeholders familiar with EF5 and hydrological modeling and finally the EF5 modeling deployed at RCMRD. Over all, thirty-three (33) experts attended the EF5 workshop both in Kenya and Uganda. At the end of the workshop, the RCMRD Director, Dr. Emmanuel Nkurunziza, gave closing remarks and the workshop participants received certificates.


New book: Hydrological Remote Sensing

Features

  • Presents an overview of the past, current and future remote sensing observations of the precipitation, soil moisture, evapotranspiration and total water storage
  • Reviews the various applications of remote sensing in hydrological/land surface/climate modeling and Ensemble Square Root Filter (EnSRF) data assimilation
  • Demonstrates techniques to help reduce devastating disasters triggered by hydrological hazards such as floods and landslides
  • Explains how remote sensing, modeling and data assimilation can be utilized to improve societal resilience and environmental sustainability
  • Shows how to create real-time flood and drought monitoring systems

Summary

Environmental remote sensing plays a critical role in observing key hydrological components such as precipitation, soil moisture, evapotranspiration and total water storage on a global scale. As water security is one of the most critical issues in the world, satellite remote sensing techniques are of particular importance for emerging regions which have inadequate in-situ gauge observations. This book reviews multiple remote sensing observations, the application of remote sensing in hydrological modeling, data assimilation and hydrological capacity building in emerging regions.


HyDROS' Grand Challenge is to observe and predict the storage, movement, and quality of water across space-time scales by integrating advanced sensing technology and numerical predictive models into an end-to-end research and application framework.

HyDROS' Mission is to propose technological solutions for mitigating the impacts of climate change and natural hazards through interdisciplinary research and education by using the latest remote sensing technology, information technology, and hydrological models in collaboration with private and public organizations at both local and international levels for the creation of a resilient society.

We will pursue our Grand Challenge and Mission through transdisciplinary research and education involving faculty, students, and scientists with Engineering, Sciences, Math, and Socioeconomic Sciences backgrounds as well as cooperation with universities, governmental agencies, private companies/industry, and international counterparts.

We are always looking for talented and enthusiastic students and researchers. We have advised students major in Civil Engineering, Hydrology (Water Resource Engineering), Environmental Science (Water Track), Geography, Meteorology, Computer Science and Geoinformatics.
