1. Developing a 3D turbulence-resolving numerical model for fine sediment transport in the oscillatory boundary layer in order to understand how turbulencesediment interactions can determine the state of muddy seabed (transport modes). 2. Studying the attenuation of turbulence due to the presence of sediment via the interplay between sediment-induced density stratification and enhanced viscosit...
مسئله انتقال رسوب در رودخانه یکی از مسایل مهم در مباحث مهندسی رودخانه هیدرولیک رودخانه و مورفولوژی رودخانه می باشد و به عنوان یکی از بزرگترین مشکلات بهره برداری از آبهای سطحی در جهان مطرح است در این تحییق به بررسی انتقال رسوبات چسبنده در خور رودخانه ای چند شاخه danshui توسط مدل عددی یک بعدی و غیر دائمی mikell پرداخته شده است خور رودخانه ای danshui در شمال کشور تایوان قرار داد و بزرگترین سیستم خ...
Desulfurivibrio alkaliphilus strain AHT2(T) is a strictly anaerobic sulfidogenic haloalkaliphile isolated from a composite sediment sample of eight hypersaline alkaline lakes in the Wadi al Natrun valley in the Egyptian Libyan Desert. D. alkaliphilus AHT2(T) is Gram-negative and belongs to the family Desulfobulbaceae within the Deltaproteobacteria. Here we report its genome sequence, which cont...
Community composition of the infaunal bivalve fauna of the St. Lucie Estuary and southern Indian River Lagoon, eastern Florida was sampled quarterly for 10 years as part of a long-term benthic monitoring program. A total of 38,514 bivalves of 137 taxa were collected and identified. We utilized this data, along with sediment samples and environmental measurements gathered concurrently, to assess...
A mixing model derived from first principles describes the bulk density (BD) of intertidal wetland sediments as a function of loss on ignition (LOI). The model assumes that the bulk volume of sediment equates to the sum of self-packing volumes of organic and mineral components or BD = 1/[LOI/k1 + (1-LOI)/k2], where k1 and k2 are the self-packing densities of the pure organic and inorganic compo...
