During a routine cleaning, a technician holds up a water-quality sonde to show its sensors. Each sensor measures a different water-quality value, such as temperature or dissolved oxygen. A central wiper helps keep the sensors clean between technician inspections.

The sonar equipment monitors streambed elevation near the bridge footing to measure scour depth. Accurately measuring scour depth is essential for evaluating bridge safety. During short storm events, crews may not arrive in time to monitor in real-time. Without continuous monitoring, the deepest scour could be missed if the hole refills before inspection.

Benthic Cyanobacteria

Benthic cyanobacteria are a type of photosynthetic bacteria that live on the bottom of aquatic environments, such as lakes, rivers, oceans, and wetlands. The term "benthic" refers to their habitat in the sediment or substrate of these water bodies, as opposed to being free-floating in the water column (planktonic).

A piezometer is a device used to measure the pressure of a liquid, particularly water, within a specific point of a system, such as soil, rock, or a pipe. It is widely used in geotechnical, hydrogeological, and civil engineering applications to monitor water levels, pore water pressure, and hydraulic head in the ground or other systems.
