Abstract:

Sediments are particles derived from the dismantling of rocks from the land and pieces of shell and remains of marine organisms that contain organic matter, included carbonate sediment. The total carbonate sediment content was influenced by many factors, such as sediment grain type. This study aimed to determine the carbonate content in sediments and to determine their relationship to the sediment grain characteristic on the Cilacap coast. The sediment's carbonate content used the titration method, while the sediment grain test used a dry filter. Statistical analysis was used to determine the

Abstract:

Sediment characteristics are described through grain size variables so that an understanding of sediment is built based on the interpretation of these variables. The distribution of sediment grain sizes reflects the viscosity and strength of factors acting on the depositional environment. That is why, knowledge of the grain size characteristics of sediments in certain depositional environments is very necessary in relation to the management of that area. This research was conducted to determine the extent to which sediment grain size variables describe sediment character. To reveal this, sedim

In the spring of 1985 the first goetechnical reconnaissance of recent Saguenay Fjord sediments took place, in which were recorded the two Saint-Jean-Vianney slides of 1663 and 1971.

The mineralogy of the recent sediments is like that of the raised marine deposits of the area, except for the organic content, which is higher. The microstructure of the sediment is quite typical of flocculated marine soils. The freshly sedimented soil, in its sedimentary environment, has gained strength and sensitivity (up t

This regularity disturbs in rivers under the influence of volcanic eruptions, where the most significant increasing of sediment yield is observed after major eruptions. Existent maps of mean

Conventional sediment classification methods based on Multibeam Echo System (MBES) data have low accuracy since the correlation between features and sediment has not been fully considered.

Toward these problems, we propose a seabed sediment classification method using spatial statistical features extracted from angular response curve (ARC), topography, and geomorphology.

Abstract:

Abstract This study aims to determine the characteristics of sediments found in the Jeneberang River specifically in the upstream part. The data required includes the results of sieve analysis, grain diameter of the sediment and the density of the sediment. The study was conducted by taking samples from the segments around Sabo 7-1. The data obtained indicate that the gradation of sediment particles consists of fine sand, medium sand, coarse sand, fine gravel and coarse gravel with a median diameter (D50) of 0.5-13.10 mm and specific gravity values ranging from 2.659-2.682 gr/cm.

Abstract:

Pacitan Bay is one of the semi-enclosed waters on East Java's south coast. This area is well-known for having a large fishing port as well as a beach tourism area. The dynamics of Pacitan Bay's waters due to the influence of currents, waves, and the input of water masses from the mainland are thought to affect the characteristics of the waters' bottom sediments. The objective of this study was to map the characteristics of bottom sediments and the distribution of organic substance. This research also analyzed the relationship between sediment characteristics and the concentration of organic su

Abstract:

Human activities for exploitation and utilization of coastal zones have transformed coastline morphology and severely changed regional flow fields, underwater topography, and sediment distribution in the sea. In this study, single-beam bathymetry coupled with sediment sampling and analysis was carried out to ascertain submarine topography, geomorphology and sediment distribution patterns, and explore sediment provenance in Qinzhou Bay, China. The results show the following: (1) the underwater topography in Qinzhou Bay is complex and variable, with water depths in the range of 0–20 m. It can be

Twelve plots previously settled in the original gap and its surrounding forest were used to collect sediments in the dry and wet season in 2019 to assess the difference in sediment properties and nutritional state caused by the self-recovery of the vegetation. Sediment temperature and pH were measured in field, while the contents of total organic carbon (Corg) and total nitrogen (Ntot) were subsequ

Abstract Physical and chemical properties of bottom sediment and suspended particu-lates were studied at the Kingston stormwater pond. The bottom sediments have accumulated in the pond at an average rate of 0.02 m/year and comprised gravel, sand, silt and clay; the first two materials accumulated only by the inlet and the last two were spread throughout the pond and represented up to 45% and 54% of the total sediment, respectively. The water content of the accumulated sediment ranged from the low of 48% (by the inlet) to the high of 78% (at the outlet), by volume. The assessment of total metal

A dynamic, pollutograph based sewer flow quality simulation model is an essential tool to aid in the control of intermittent pollution from combined sewer overflows (CSOs). Such a model can be used in conjunction with river impact models to provide an objective methodology for the control of intermittent sewage discharges.

Sediment characteristics in the littoral zone of lakes affect the distribution, biomass, and productivity of benthic organisms and affect chemical exchanges with the water column, yet we know very little about their distribution.

The distribution of sediment water content in small lakes differed from the general patterns described for large lakes and ocean. Sediment water content was generally high in

Alluvial rivers are shaped by sequences of water flows excavating their channels. Observations show that besides the magnitude, also the frequency and duration of streamflow oscillations might be important for the river channel formation. In addition, the river morphology appears influenced also by both size and degree of uniformity of the sediment. Nevertheless, many morphodynamic studies still represent the flow regime with a single value of the discharge, often corresponding to the bankfull condition, and the sediment with its median grain size.

At very high levels, sediments can cause pollution or vulnerability such as decreasing of dissolved oxygen, coral bleaching, and increased the eurotrification processes.

The variation in the distribution of different categories of sediment could result in the changes in river channel formation and habitat.

Sediment particle size and heterogeneity play an important role in sediment denitrification through direct and indirect effects on, for example, the material exchange rate, environmental gradients, microbial biomass, and grazing pressure. However, these effects have mostly been observed in impermeable sediments. On the other hand, the material exchange of permeable sediments is dominated by advection instead of diffusion, with the exchange or transport rates exceeding those of diffusion by two orders of magnitude relative to impermeable sediments.
