Expanding the Port Everglades: Real-Time Monitoring of Water Quality Conditions from Planned Dredging Operation
The Port Everglades in Broward County, Florida, serves large trade vessels and cruiseliners and incoming and outgoing recreational boaters. However, as cargo ships become larger, the port must expand. 
 
A dredging project led by the US Army Corps of Engineers will substantially deepen and widen the port's navigation channel to accommodate larger Panamax cargo ships and modern cruise liners. 
 
As a result of this project, a large amount of sediment will be displaced into the water column. This suspended sediment may settle outside of the project area, burying benthic organisms like corals, and possibly carrying harmful particulates to other regions.

Water quality monitoring is essential for safeguarding public health, protecting ecosystems, and ensuring the sustainability of water resources. Contaminants such as industrial pollutants, agricultural runoff, and sewage discharge can severely impact aquatic life and pose serious risks to human health if left unchecked. 
 
Traditionally, water quality monitoring has been a slow and labor-intensive process, requiring samples to be collected, transported to a lab, and analyzed—a process that can take days. 
 
However, with the advancement of real-time sensor technology, environmental agencies, researchers, and industries can now monitor water quality instantly.

The City of Hazelwood is a suburb in St. Louis County, Missouri, home to around 25,500 people. Recently, the community has suffered increased flash flooding following severe storms, prompting the need for the installation of a flood monitoring system. 
 
In 2022, a NexSens X2 data logger was installed to monitor water level and rainfall in real-time, with the aim of reducing the loss of life and property as a result of extreme weather events. 
 
[caption id="attachment_39411" align="alignnone" width="940"] The latest flood event at Coldwater Creek, where the water level rose by 14 feet, exceeding the height of the X2 by three feet. The sensor can be seen behind the wall that usually contains the Creek.
