The zone between the water table and the surface is called the zone of aeration.
潛水面與地表之間的地帶稱為飽氣帶。An unconfined aquifer has a water table at its top and water in direct contact with the soil atmosphere.
非承壓含水層在它的上面有一個潛水面且水與土壤大氣直接相連。Water table is a surface on which the pressure is atmospheric.
潛水面是一個其表面上壓力等於大氣壓力的面。The level of the water table also fluctuates slightly with the season.
潛水面的高度也隨著季節而稍有波動。When water reaches the saturated zone beneath the water table, it oozes slowly downward, and laterally.
當水到達潛水面以下的飽和帶時,它就緩慢地向下和側向滲透。The segment of the boundary above the water table and below the phreatic surface is called the seepage face.
水面以上和潛水面以下的一段邊界叫做滲出面。Just above the water table, the pores are practically saturated.
稍高出潛水面的孔隙實際上是飽和的。The saturated zone is bounded above by a water table.
飽和帶的上界面為潛水面。Below the water table is the zone of saturation.
潛水面以下就是飽水帶。Thus, the next 1500 hours correspond to the base flow recession period. it is obvious that the aquifer with ampler water storage will produce larger subsurface runoff. from the above numerical simulations, one can see that the b - s model can reasonably simulate the subsurface runoff varia - tion in the two extreme conditions
而在持續了1500 h以後入滲突然都變為0對應著實際情況中徑流的消退期,顯然儲水較多的潛水面的地下徑流比較大,而隨著退水的持續進行行,地下徑流也越來越小The water that fills the pores below the water table is not static.
充填在潛水面以下孔隙中的水不是靜止的。Due to the nonlinearity of the boussinesq equa - tion, exact analytical solutions are difficult to obtain
下面將給出這個潛水面的控制方程在在某些假設條件下的解析解Beven 18 suggested that when it is applied in its original form to a river basin with thin soils over an imperme - able base, the quasi - steady state approximation holds. however, he also noted that for a variety of alternative transmissivity profiles, or when the saturated depth of the aquifer is large, the deviation in the actual shape of the water table from a steady - state shape can be both large enough and last long enough to call into question the assumption of quasi - steady dynamics
Beven 18也也指出這種「擬穩定」的地下徑流機制雖然能夠較好地應用於那些不透水層之上的土壤厚度比較薄的流域,但對于那些非飽和土壤層的厚度隨空間的變化較大也就是地下水位的變化比較大,或者潛水面的厚度較大的流域,使用這種「擬線性」的topmodel地下徑流機制就容易產生問題The longitudinal wave velocity in saturated soil could not only be useful, but reflect more information as well. the shear wave velocity may be different from the shear sewv, the difference is proved to be caused by porosity and structure factor
認為潛水面下縱波速度能反映更多的信息,並且,橫波速度與骨架的橫波速度也可以由孔隙率及結構因子引起差異。Subsurface runoff is obviously closely related with soil water movement in the unsaturated soil zone and dynamic change of the groundwater table. there - fore, it is necessary to develop the subsurface runoff model with a physical base associated with recharge on the aquifer and total storage in the reservoir. also a soil model with a dynamic representation of the groundwater table makes it possible and reasonable to represent a more logical subsurface runoff parame - terization
地下徑流顯然與非飽和土壤層中的水分運動以及地下水位的動態變化密切相關,因而有必要發展考慮土壤含水量與潛水面science in china ser . d earth sciences 376中國科學d輯地球科學第36卷水分通量以及地下水位動態變化的土壤水模型相適應且具有物理意義的地下徑流模型;同時地下水位動態表示的土壤水模型也為發展更為合理的地下徑流模型創造了很好的條件Study of excavation of water surface for constructing jiaozuo as a city with mountain and water landscape
焦作市開挖潛水面建設山水園林城市研究In order to derive this equation, one has to assume no spatial variability in k, f and n, to neglect the effect of capillary rise above the groundwater table, and to invoke the dupuit - forcheimer approximation, which states that the hydraulic head is independent of depth
圖1潛水面的示意圖為了利用dupuit - forcheimer假設推導出以上的方程,必須假設k , f以及n t在整個潛水面上的空間不變性,同時忽略潛水面上的水分的毛細運動This model is validated by a subsurface flow separation algorithm for an ex - ample river basin, which shows that the new model can simulate the subsurface flow reasonably. keywords : subsurface runoff parameterization, boussinesq - storage equation, water storage and re - charge. hydrological processes including surface runoff, subsurface runoff, and soil water movement play a great role in land surface processes
文中基於boussinesq - storage方程建立了同時考慮潛水面水分儲存和非飽和層水分入滲兩方面影響的地下徑流機制,並利用流域水文資料以及地下徑流分離演算法驗證了所建立模型的可靠性,結果表明該模型能夠比較合理地模擬地下徑流的變化情況11 can be a subsurface runoff parameterization with water storage and recharge based on the boussinesq - storage equation 625 written as 11 ee sineee sine. nnnnktaxbtnnuxktbtnsknnktbtaxnnuxktbtnsknnhxtwfnxhkbwfnxhkb letting t tend to infinity, one can get the steady aquifer function hs 13 : 1 sinee. uxaxnsksnnnfnhxxhkb multiplying through by the specific yield, f, and in - tegrating with respect to x between 0 and l gives the drainable storage associated with this steady - state free surface
下面考慮整個潛水面的一種穩定狀態,也就是是對于任意一個恆定的入滲,當時間時潛水面將達到穩定的狀態不再發生變化,這個時候顯然有, 0 , . sntnt t , ssqnl也就是入滲補充量等於地下徑流量Traditionally, the saturated zone is modeled as a simple lumped continuity equation :, dsitqsdt where t is time, s is the total storage in the reservoir, i is the spatially integrated volume of incoming wa - ter, and q is the discharge subsurface runoff which only depends on the total storage s. this kind of subsurface runoff model has many different parame - terizations 10 12, however it has a very common char - acteristic that the subsurface runoff is just a sin - gle - valued storage - discharge function
對于大尺度水文模型而言,目前常常採用的是集總式的地下徑流機制,其連續性方程一般可表示為d , dsitqst ? 1這里t是時間, s表示整個流域潛水面土壤層的飽和區域總的水分儲存量, i t表示t時刻土壤的非飽和區域向整個潛水面的水分補充量, q s表示僅依賴於水分儲存量s的地下徑流量量分享友人
