A Comparison of Precipitation Downscaling Procedures to Guide Studies of Climate Change Impacts on Flooding and Water Resources

This was a collaborative project with Dr. Eve Halper from the Bureau of Reclamation (Reclamation), Phoenix Area Office. The project was funded by the Reclamation Science and Technology Grant Program under a cooperative agreement between HRC and the Reclamation Lower Colorado Region (Agreement # R16AC00024). In recent years, Reclamation and other agencies have been engaged... Read More

Viet Nam Operational and Analysis Flash Flood Guidance Systems

HRC implemented its Flash Flood Guidance System (FFGS) technology for the Vietnam Institute of Meteorology, Hydrology, and Climate Change (IMHEN) in Hanoi, Viet Nam.  HRC adapted the Flash Flood Guidance System) to support flash flood warnings in Viet Nam.  The systems were adapted for the specific operational conditions in Viet Nam and were applied with...
