Experimental test system
The water infiltration measurement system consists of a Mariotte bottle
(used to control
the
water head constant; radius 5 cm, height 50 cm), cylindrical transparent
Perspex chamber (radius 10 cm, height 100 cm), an adjustable lifting
table (Wuhan Red Star Yang Science & Technology Co., Ltd., China) to
adjust the water head between the soil surface and the water outlet of
the Mariotte bottle, a Meacon gravity sensor (Hangzhou Meacon Automation
Technology Co., Ltd., China), an RX9600 data collector and Mik-Bsqd
signal amplifier (Hangzhou Meacon Automation Technology Co., Ltd.,
China), and a computer, as shown in Fig. 2. In the experiments, the
scanning time interval was 2 s and the water head was 1 cm at the soil
surface.
