英文摘要 | Based on the field investigation, the typical sediments (sandy silt) undisturbed/disturbed and the land surface water are sampled in the Muguandao Reservoir area. The temporal-spatial variations are studied for the effects of wind and temperature on the salt release from the sediments by means of the sediment column and tank experiments. And the salt fluxes from sediments are calculated. These conclusions can lay a scientific foundation for the evaluation and prediction of the water quality in the reservoir. The results show that the salt release follows a distributional regularity, i.e. the salinity is homogeneous in the layer from the water surface to the 4.0 cm above the water-sediment boundary, inhomogeneous in the layer between 0.0 cm and 4.0 cm above the boundary, with a minimum salinity at the 3.0 cm above the boundary. Salinity distribution is non-linear in the water under the influence of temperature, i.e. high salinity is located in the layer between 0.0 cm and 7.5 cm above the water-sediment boundary, and very low salinity in the layer from the water surface to the 7.5 cm above the boundary. The salt flux from the sediments is determined by a power function under the influence of wind or temperature which is favorable for salt release and the salt exchange between the reservoir water and the reservoir bottom sediments. ©2009 IEEE. |
