- Ground water is the water contained in interconnected pores located below the water table in an unconfined aquifer or located in a confined aquifer. 地下水是指赋存于地面以下岩石空隙中的水,狭义上指赋存于地下水面以下饱和含水层中的水。
- Below the water table is the zone of saturation. 潜水面以下就是饱水带。
- The main factors of the DRTA model are: (1) depth to water table, (2) rating media of the vadose zone, (3) thickness of rating media in the vadose zone and (4) aquifer thickness. DRTA模型包含有地下水埋深、包气带评分介质、包气带评分介质的厚度和含水层厚度4个因子;
- The lowering of ground water table and increase of salinity in aquifer under the condition of leaching treatment are lower than that under the condition of normal treatment. 抽取地下微咸水灌溉后,淋洗灌溉定额条件地下水位的下降幅度及含水层盐分的增加量都比正常灌溉定额条件下有所降低。
- The paper introduces seven factor of DRASTIC model: Depth of water table、Net recharge、Aquifer media、Soil media、Topography、Impact of Vadose Zone and Hydraulic Conductivity. 介绍了DRASTIC模型的七个评价因子:地下水埋深、含水层净补给量、含水层介质类型、土壤类型、地形坡度、包气带介质I的影响和含水层的导水系数。
- The water table has been lowered by drought. 由于天旱,地下水位降低了。
- Just above the water table, the pores are practically saturated. 稍高出潜水面的孔隙实际上是饱和的。
- Based on data of pumping test, this paper summarized the variational law of well in phreatic aquifer of loess and the diversified relationship between water table and pumping time. 本文根据抽水试验资料总结了黄土潜水井水跃值的变化规律并分析了其成因;总结了水位降深随抽水时间的变化关系,并建立了经验公式;提出了公式中参数的确定方法。
- The saturated zone is bounded above by a water table. 饱和带的上界面为潜水面。
- Water table is a surface on which the presure is atmospheric. 潜水面是一个其表面上压力等于大气压力的面。
- This lowers the water table and reduces soil alkalinization. 这能降低水位,减少土壤的碱份。
- Water table is a surface on which the pressure is atmospheric. 潜水面是一个其表面上压力等于大气压力的面。
- The water that fills the pores below the water table is not static. 充填在潜水面以下孔隙中的水不是静止的。
- Vadose zone is below weathering crust face and on water table. 潜流岩溶带的上限是枯水期的最低潜水面,该带地下水受压力梯度控制并沿水平方向流动,最明显的岩溶特征是出现大型的水平溶洞,地下暗河及其溶蚀孔、洞、缝发育段。
- The level of the water table also fluctuates slightly with the season. 潜水面的高度也随着季节而稍有波动。
- The distance of the water table below the soil surface must be adjusted. 必须调整土壤表面以下水位的距离。
- The water table of this land has nearly dried up, and needs treatment. 这块地的地下水层已经接近干枯,需要进行治理了。
