Physical and Rheological Characteristics of Sediment for Nautical Depth Assessment in Bushehr Port and Its Access Channel

Sedimentation in ports and waterways covered with fine deposits is a significant challenge harbor management. The top layer of the bed such areas typically consists fluid mud, for which dredging complicated less efficient. goal this paper to investigate physical rheological characteristics sediment nautical depth assessment Bushehr Port its access channel. In study mud was detected by hydrographic surveys dual-frequency echo sounder. Moreover, properties various parts channel port were analyzed through comprehensive sampling field complementary laboratory studies, including grain-size analysis distribution, carbonate organic matter content, rheometry, consolidation settling tests. It found that water contents concentration, clay-size fractions are most important factors area. results indicated fraction surficial between 18 31%, categorized it as cohesive sediment. terms mineralogy, mostly content 52.9 57.2%. showed concentration yield stress samples lower than 1030 kg/m3 123 Pascals, respectively. Based on obtained characteristics, concluded bottom approach can be practically implemented
