图4 原位竖管法测定河床沉积物渗透系数示意图。L为测管内河床沉积物的长度,H1H2分别为t1t2时刻所对应的测管内水头高度。
Fig.4 Schematic diagram showing the measurement of riverbed hydraulic conductivity using in-situ standpipe method. L is the thickness of the measured riverbed inside the standpipe, H1 and H2 are the water level inside the standpipe at the testing time t1 and t2, respectively.
