| Abstract: | Of all known sediments “mud” is probably the one attracting the most attention today. It is certainly the only type of sediment being studied by investigators of a wide variety of scientific and technological disciplines. The experts in the latter category deal with it very actively because of the great number of problems that have emerged during the past decades as a consequences of the expansion of many harbors and of an increasing pollution of surface waters. Besides th geologist, for whom “mud” is the basic material for clay, shale, and slate, the sidementologist, hydraulic engineer, harbor-manager, soil scientist, biologist, the ecologist, and many other professionals are very much interested in this particular sediment. Indeed, its importance does not only lie in its geological meaning nor in the fact that it is a substratum for living organisms and vegetation, but as a result of its high adsorption and cation exchange capacity making it one of the most active carriers of many adsorbed pollutants, causing a troublesome, fast accumulating cohesive spoil in waterways accessing to major harbors. |
