Oct 15, 2018· The results showed that sediment load had been reduced by 70.5% during the changing period from 1990 to 2012 compared to that of the baseline period from 1955 to 1989. Human activities accounted for an average of 93.6 ± 4.1% of the total decline in sediment load, whereas climate change contributed 6.4 ± 4.1%.

· Barnard says research indicates that human activity has reduced the sediment load leaving the Bay, and that sand mining is "certainly a contributing factor" to this phenomenon. Sand mining, which uses hydraulic suction to slurp up sediment from underwater mineral deposits, has been ongoing in the Bay Area for more than 70 years.

Streams are able to transport sediment very long distances. There are different types of material carried by a stream depending on the size and chemical properties. 1) Dissolved load - transport of ions and chemicals in solution - responsible for the saltiness of the sea. 2) Suspended Load - typically the largest load - clays, silt and fine sand.
