Physical Tank Experiment Investigation on Rainfall Producing Groundwater Level in Homogeneous Material Slopes

Table 1

Characters of the three typical tank models.

Type	Characters of applications
Simple tank model [9]	Simple model; assumed low slope angle; no surface runoff; negligible lateral water flow supply
Surface runoff tank model [10]	Considering surface runoff; requires maximum infiltration rate test; less lateral water flow supply
Lateral water flow supply tank model [11, 12]	Increasing model complex; relatively high error; any slope angle
