Geological sequestration (GS) of carbon dioxide (CO2) is considered as one of the most promising technologies to reduce the amount of anthropogenic CO2 emission in the atmosphere. To ensure success of...
The importance of the study of saline/fresh water incursion cannot be over-emphasized. Borehole sampling has been extensively used, but it is intrusive, quite expensive and time consuming. Electrical ...
为了研究淡水与微咸水连续和间歇入渗特性的差异,采用矿化度1.33g/L的淡水与矿化度3g/L的微咸水,在黏质土壤条件下进行了一维积水连续入渗及间歇入渗试验。研究结果表明,采用微咸水入渗可以改变土壤的结构特性,从而增大土壤的入渗能力;利用一维代数入渗模型对试验资料进行处理,结果表明模型可以比较精确地描述微咸水入渗过程;入渗水为淡水时,间歇入渗减渗,而入渗水为微咸水时,间歇入渗增渗;间歇入渗的循环...
针对矿化度均为3g/L的微咸水入渗时,土壤初始含水率对土壤入渗过程的影响,采用室内均匀土柱一维垂直入渗实验方法,分别对初始含水率为2.25%、8.18%、13.12%、16.40%的土柱入渗过程进行了研究。分析了不同土壤初始含水率对累积入渗量和湿润锋推进深度以及土柱剖面含水率的影响。采用Kostiakov模型对累积入渗量和时间的关系进行了拟合,结果表明累积入渗量与初始含水率呈负相关关系。采用幂函...
为了合理开发和利用黄淮海平原浅层地下微咸水,2003~2005年在中科院河北南皮生态实验站连续以3g/L的微咸水对冬小麦进行田间灌溉试验,分析了微咸水灌溉对土壤含盐量、土壤溶液盐分含量、电导率以及冬小麦产量的长期影响,为建立华北地区冬小麦微咸水灌溉的合理灌溉制度和微咸水的合理利用提供理论依据。结果表明,连续利用3g/L的微咸水灌溉,会造成土壤表层盐分的累积,尤其在降水量偏少的年度会使作物受到盐...
通过室内3g/L微咸水的入渗试验,分析了不同微咸水入渗水量对土壤剖面含水率、含盐量、脱盐效率和阳离子分布的影响。结果表明,利用3g/L的微咸水进行垂直一维积水入渗,入渗水量较小时,基质势是水分运动的主要动力,入渗量继续增大时,重力势逐渐取代基质势成为水分运动的主要动力;采用3g/L的微咸水入渗,可以使上层土壤脱盐,但使湿润锋处的含盐量急剧增加且达到最大值;湿润锋处含盐量与入渗水量符合指数函数...
The objective of this study was to investigate the influence of salinity on the effectiveness of surfactantsin the remediation of sediments contaminated with phenanthrene (PHE). This is an example of ...
Salinity and temperature data from the Gulf of Riga, a semi-enclosed sub-basin of the Baltic Sea, were analyzed with a focus on interannual and seasonal variability. The data were compiled from meas...
Fresh water flows counterbalance salinity intrusion in the coastal zone of Bangladesh. To quantify the required fresh water, requires a detailed understanding of physical phenomena including tidal mot...
The effects of furrow saline water irrigation (EC=8dSm-1) on the emergence and growth of maize were investigated under two different bed shapes (flattop and sloping beds) and three different soil typ...
Compared with good quality water, the use of saline water increases the amount of water used for crop growth. An increased amount of saline water affects fibre quality. A field study was conducted to ...
