This paper studied transformation among atmosphere water,surface water,soil water and ground water in 8 aspects,which is important for water resources assessment,water requirement prediction,reasonable water resources development and utilization and water saving irrigation.
"四水"是指大气水、地表水、土壤水和潜水,"四水"之间的相互转化关系研究,对水资源评估、供需预测、合理开发利用水资源和节水灌溉都有十分重要的意义。
The theoretical model to reveal the mechanism of delayed gravity response is established on account of the effects of detention of water by capillarity and boundary friction in the unsaturated zone and elasticity of aquifer skeleton with falling of ground water level.
为揭示潜水延迟给水的机理,本文建立了考虑毛管滞水和弹性储量影响的潜水三维非稳定井流理论模型,并经实例验证。
