Potentially Toxic Elements Contamination in Sediment, Surface and Pore water of Maharlu Saline Lake, South - West Iran
Maharlu Lake, located in the SW of Iran, has acted as a sink for various wastewater discharges in the last few decades. This study aimed at assessing potentially toxic elements (PTEs) distribution in sediment, surface and pore water samples of Maharlu Lake. To achieve that, the samples were collected from each compartment and the total concentration of PTEs (Al, Fe, Sc, Cr, Co, Ni, Zn, As, Sb, ...
متن کاملLimnol. Oceanogr., 44(2), 1999, 425–430
‘‘Peepers’’ (dialysis samplers) rely on exchange across a dialysis membrane between fluid-filled cells and the surrounding sediment in order to sample the pore water at various depths. In the current study, we show that under some realistic circumstances, where there is a large density difference between the pore water and the cell fluid in permeable sediments, the resulting convective motion i...
متن کاملTreatment of expansive soils with quality saline pore water by cyclic drying and wetting
Expansive soils can be found in many parts of the world particularly in arid and semi-arid regions. These soilspose a significant hazard to civil engineering structures due to its high swelling and shrinkage potential. This paperpresents the results of an experimental program developed to investigate the effect of cyclic drying and wetting on theswelling potential of expansive soils with variou...
متن کاملInterpretation of measured concentration profiles in sediment pore water
A robust numerical procedure for biogeochemical interpretation and analysis of measured concentration profiles of solutes in sediment pore water has been developed. Assuming that the concentration-depth profile represents a steady state, the rate of net production or consumption as a function of depth can be calculated, together with the flux across the sediment-water interface. Three kinds of ...
متن کاملSediment Transport Dynamics in River Networks Induced by Water Diversion
A river network is a typical completely open system formed by interconnected river channels. The interactions between the imports of a river (water and sediment) and the channel will cause the change of the channel patterns. This is actually a feedback between the erosion and the sedimentation states of the channel via an adjustment of the sedimentcarrying capability of the stream. This feedbac...
