In the 1960’s Bengt Nilsson developed a suspended sediment sampler for taking vertically integrated water samples in rivers. He did so at the Department of Physical Geography at Uppsala University, in the Geomorphological Laboratory at Norbyvägen, as a part of his doctoral dissertation and in the framework of the International Hydrological Decade, IHD.

During a visit to Cartagena de Indias, Colombia, the other week, Dr. Ulf Erlingsson of Lindorm, Inc. made some observations using a drone. The video below shows the interesting situation that is also visible on satellite images in Google Earth. This is the end of a coastal sediment transport and it ends in turbulence when an opposite direction current mixes with the high-turbidity nearshore wave-induced current. It would be quite interesting to see results of a study of that area using modern

In the summer of 2018, the newest SediMeter™ was deployed in two dredging projects to monitor sedimentation and near-bed turbidity on sensitive bottoms near the work zone. In each case, three instruments were deployed in the area of concern, and a fourth instrument was deployed as a reference station in a similar environment but removed from the impact. One of the sites is in Canada, the other in th

The ongoing dredging of Miami Harbor has caused siltation (the accumulation of sediments) on the coral reefs outside the harbor. In a settlement of a recent lawsuit, the contractor, U.S. Army Corps of Engineers (USACE), has agreed to pay $400,000 for moving corals out of the way. They are not using any instrument for measuring the sediment accumulation, even though such an instrument exists, is being manufactured right in Miami, and costs less than $2,000 per instrument.
