Description: The US DH-95 sampler is a streamlined 29-pound suspended sediment sampler. It has a tail section constructed of plastic and a bronze body coated with plastic to meet the requirements for use as a water-quality sampler. The body coating is a commercially available material with the trade name "PlastiDip".

The US DH-95 is a hand-line suspended-sediment/water-quality sampler. The sampler can be lowered and raised, hand over hand, with a flexible suspension line. The US DH-95 meets the protocols for water-quality sampling as outlined in the USGS’s National Field Manual for the Collection of Water-Quality Data7.

The US D-95 suspended-sediment and water-quality sampler is a depth-integrating sampler designed for use in streams not exceeding 15 ft in depth. It meets the protocols for water quality sampling as outlined in the USGS’s National Field Manual …

A USGS scientist about the collect a water sample with a DH-95 sampler (the white torpedo looking device). After sampling, another scientist takes the bottle of water and pours it into the churn. Having another scientist do this prevents contamination of the sample.

sediment discharge include suspended-sediment sampling, bed'material sampling, and bedload sampling. Without direct sampling, however, equations based on incipient motion or energy are typically used. Unfortunately, these formulations require discharge measurements and knowledge of size distributions and depth-integrated sediment concentrations.

Aerial imagery of site with indication of 2017 and 2018 sediment sampling locations. The 2017 sampling location could not be used during the 2018 flushing event because the higher flows were overtopping the bridge creating an unsafe environment for staff and equipment.

The Federal Interagency Sedimentation Project designed and developed the US DH-95 suspended-sediment sampler, a depth-integrating instrument for use in streams not exceeding 15 feet in depth.
