A new video from the Department of Homeland Security Science & Technology Directorate shows how early warning flood sensor technologies like the AWARE Flood System are improving communities’ resiliency to flood events.
In 2018, the U.S. Department of Homeland Security Science & Technology Directorate (DHS S&T) collaborated with Intellisense Systems, Inc. to design, develop and test a network of inexpensive, readily-deployable inundation sensors to respond to the increasing risks of flooding. Flooding is now the nation’s leading natural disaster in terms of property damage and loss of life. Over the last 30 years, floods have accounted for $8.2 billion in damages and 105 fatalities every year. Much of this devastation can be allayed by deployable flood sensors with Internet of Things (IoT) technology that monitor flood-prone areas in real time and rapidly alert first-responders, city officials, and citizens to flooding events.
Now the DHS S&T has released a video promoting the benefits of flood sensor technology like Intellisense’s AWARE Flood System. It highlights the system’s relative accuracy within a 1/2 inch of water level, as well as its ability to detect minimal water level rise. These capabilities allow emergency managers to monitor and quickly respond to urban flash flooding, coastal zone tidal surge, dam and reservoir height fluctuations, and other flood hazard events. The video demonstrates that proven and dependable low-cost flood inundation sensors can offer flood hazard monitoring, alerts warnings, and notifications to communities, giving officials and citizens the time needed to respond to fast-moving flooding events.
The video also features testimonies from community leaders and officials who have benefited from the AWARE Flood System. “The accuracy of the low-cost sensors exceeded expectations for reliability and accuracy when compared to the USGS stream gauge data,” said a project manager from the Charlotte-Mecklenburg (North Carolina) Storm Weather Services. A Flood Warning System Manager in Howard County, Maryland added, “After major flooding events in both 2016 and 2018, our participation in the flood sensor project helped us refine our models and help us better understand areas that could be impacted.” Finally, an Assistant Manager at the Kentucky Division of Water (KY DOW) affirmed that, “The accuracy requirements for the KY DOW Dam Safety Program were completely met by the low-cost flood sensors.”
In addition to this video, the DHS S&T also published a performance analysis of the AWARE Flood System after a two-year deployment. The system met and in many cases exceeded the needs of the local storm weather services with water level measurements that nearly matched the existing and more expensive USGS flood gauges. The DHS S&T ultimately concludes these cost-effective and innovative technologies are invaluable to helping protect property, improve community resilience to flooding, and – most importantly – save lives.
