In contrast, in the saturated zone water flows freely into wells and springs.
The range of the saturated zone formed by 1 to 5 fractures is 16.4 [m.sup.2], 34.7 [m.sup.2], 60.9 [m.sup.2], 75.6 [m.sup.2], and 110.7 [m.sup.2], respectively.
In particular, with rainfall infiltrating inside the slope, there will appear greater positive transient water pressure and larger range of transient saturated zone on the rock slope surface.
Therefore, the saturated flow equation is a commonly used governing equation for groundwater in the saturated zone, where:
The structure of the model simplifies the hydrology of the watershed in two interconnected zones: the non-saturated zone where the potential recharge is simulated and the saturated zone where the low flow of SUP-SUB interaction is simulated (Figure 2).
Three zones were identified in these sections they are the top dry zone (less than 1m to greater than 3m) representing the superficial deposits the middle zone (Saturated zone) represents the groundwater aquifer.
These AETLs are installed radially around a central access caisson: a steel pipe 2.3 m in diameter by 7.0 m deep, excavated by hand through the undisturbed vadose zone materials down into the permanently saturated zone. A reference tensiometer is installed adjacent to each of the sampling AETLs in the surrounding, undisturbed vadose zone material.
It is generally accepted that during infiltration [theta] will decrease with increasing soil depth and a relatively moist region forms in the upper layer, where in turn a saturated zone and a transmission zone may be recognized.
TopModel assumes that the dynamic of the water cycle table is specified by a uniform subsurface runoff production per unit area over an area draining through a point and the hydraulic gradient of the saturated zone is given by the local surface topographic slope [31, 32].
Studies have also shown that bacteria are able to survive and move long distances in a highly conductive saturated zone (Anan'ev & Demin, 1971; Butler et al., 1954; McCoy & Hagedorn, 1979; Stiles & Crohurst, 1923).
