VIS determines sizes and settling velocities of suspended mud flocs without destroying the large fragile aggregates. The settling process of the flocs and aggregates can be observed directly on a screen on board the research vessel. Analysis of the video recordings was possible up to 600 mg·dm<sup>-3</sup>, which is of importance in turbid estuarine systems. Experiments with VIS in the Ems estuary showed macroflocs with settling velocities of 0.5 to 2.0 mm·s<sup>-1</sup> and sizes of 200 to 500 µm. These flocs were observed at relatively low suspended-sediment concentrations (20 to 50 mg·dm<sup>-3</sup>). During certain phases of the tidal cycle (around mid-tide) even larger aggregates were observed with dimensions in the range of 400 to 1100 µm and settling velocities of 1 to 7 mm·s<sup>-1</sup>, surviving relatively high current velocities. The large aggregates are shown to play an essential role in the phenomenon of rapid settling, as observed in various estuaries.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The determination of the sizes and settling velocities of estuarine flocs by underwater video system","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1993,"MonPub":null,"DateUpdate":"2001-09-14","DateCreate":"2001-08-20","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1993MK65700003","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":16130,"PubliDate":1993,"Pagination":"231-241","XtraPublOfAnaID":null,"ISBN":null,"Volume":"31","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44573,"SerRR":"Netherlands Journal of Sea Research.
