Loose or loosening soil is often the culprit in weakening bridge stability. Thus, an instrument that can quickly assess the soil conditions around bridge pillars became a top priority for DHS S&T, as well as state and local governments.
They discovered that increases in diarrheal disease cases were closely tied to periods of rainfall, flood recession, and changes in surface water quality, with a 1 meter drop in river height in the dry season associated with a staggering 16.7 percent increase in diarrheal disease in children under 5.
To mitigate the impact of flood disasters, the Department of Homeland Security (DHS) Science and Technology Directorate (S&T) has initiated multiple projects across the nation through its Flood Apex Program.
Columbia Engineers show for the first time that runoff extremes have dramatically increased in response to climate and human-induced changes. Their findings demonstrate a large increase in precipitation and runoff extremes driven by human activity and climate change.
On top of rising sea levels, stronger hurricanes and worsening wildfires, scientists project that human-caused climate change will result in one of the most dire consequences imaginable: a disruption in the global beer supply.
