in this paper, the large amount of sedimentation and the resultant shoreline advancements at the breakwaters of beris fishery port are studied. a series of numerical modeling of waves, sediment transport, and shoreline changes were conducted to predict the complicated equilibrium shoreline. the outputs show that the nearshore directions of wave components are not perpendicular to the coast whic...

it is well known that, contaminant transportation is a major problem in coastal zones and has to be faced when coastal structures are being planned. sea pollution not only causes environmental damage, but also impacts quality and population of sea resources. oil is the most important pollutant, pollutants emanating from industries, ships, drilling and exploration in the seabed, ship sewage, tox...

Biodiversity and community structure of macrofauna of the intertidal sandy beach at Chabahar Bay were studied for a period of ten months in 2007. A total of 32 species were observed and identified in this study so that polychaete with 16 species was numerically dominant. The results showed changing densities were influenced by monsoon season so that maximum density (1935.47 ind/m2) was observed...

based on the morphology and corallites structures, seventeen species of scleractinian corals in seven families were described from the chabahar bay, fourteen species of which are being reported for the first time from this bay. the identified species include  acropora valida dana, 1846,  acropora clathrata brook, 1891 and  acropora nausta dana, 1846 belonging to acroporidae, favia matthai vaugh...

temporal and spatial variation of zooplankton abundance, composition and biomass were examined on the chabahar bay, oman sea. the chabahar bay, a subtropical and semi-enclosed bay, provides an ideal breeding ground for many fish and shellfish. five stations were investigated along the bay. this area is under the influence of the indian ocean seasonal monsoons. zooplankton was collected with ver...

Mangrove ecosystems help mitigate climate change, are highly biodiverse, and provide critical goods and services to coastal communities. Despite their importance, anthropogenic activities are rapidly degrading and deforesting mangroves world-wide. Madagascar contains 2% of the world’s mangroves, many of which have undergone or are starting to exhibit signs of widespread degradation and deforest...

we quantified the distribution, abundance and assemblage structure of macrofauna at 22 stations in gorgan bay, seasonally in 2012-2013. also, depth, temperature, salinity, do, tom and sediment particle size were measured in each station. the highest concentration of tom was measured near the western littoral zone (10.22) while the mouth part and north-eastern area was characterized by the lowes...
