查询词典 water-tight

During the infiltration process of indirect subsurface drip irrigation, the ponded water depth changed from zero to a constant and accelerated the water movement in the vertical direction, which reduced the discrepancy of wetted distance in lateral direction and vertical direction, while the changed water depth had small influence on the wetting front movement in vertical direction to upward and downward.
