Biota-sediment accumulation factor and concentration of heavy metals (Hg, Cd, As, Ni, Pb and Cu) in sediments and tissues of Chiton lamyi (Mollusca: Polyplacophora: Chitonidae) in Chabahar Bay, Iran
Heavy metals and some organic substances which are drained into the aquatic environments and cannot be decomposed or eliminated will sink into sediments or find their way into different levels of food chain. Bioaccumulation is the process of continuous deposition and aggregation of these substances into the body tissue of living organisms. Mollusks are remarkably appropriate to be used as bio-i...
متن کاملEffect of environmental parameters on the amount of scour in marine structures
Scour is a phenomenon that occurs as a result of natural erosion by ground water flow and transport of seabed material. In this research, scour around the legs of marine structures is simulated using the FLOW3D.V.9.3™ commercial software. The general scour model consists of two components, namely, the lift and thrust forces. The drag force, that is inserted to the structure, is a combination of...

متن کاملشبیه سازی انتقال رسوب پشت موج شکن بندر انزلی با هدف مقایسه نرم افزار ایرانی PMO Dynamics و MIKE21
Construction of ports and coastal structures actually affects the coastal flow pattern and results in the changing of the sedimentation pattern. The research carried out in this paper, aims to simulate sedimentation process following the construction of the Bandar-e Anzali New Breakwaters at the site, using Iranian developed PMO hydrodynamics and well known MIKE21 modeling package developed by ...
متن کاملThe Effect of Environmental Parameters (Depth and Sediment) on the Benthic Molluscs Density and Diversity in the the crater of Nayband Bay
In order to investigate the sedimentary texture, diversity and density of benthic molluscs, 55 stations at 9 transect were collected in the Nayband Bay.Samples were taken with a Van Veen grab (0.022 m2) in 3 replications in each site.Using a Particle Size Analyzer instrument revealed that the sediment texture was dominated by sand with 7 sub distinct sub sediment. Semelidae,Veneridae and Tellin...
