Results analysis of seepage for various water-level characteristics.

	Upstream water level (m)	Water-head beyond the antiseepage layer (m)	Cutting water-head of the antiseepage layer (m)	Percentage of cutting water-head (%)	Seepage gradient	Water-level characteristic
1	1422.38	1402.52	19.86	39.42	13.40	Largest water-level difference between upstream and downstream in 2015
2	1427.36	1414.49	12.87	23.25	10.51	Highest upstream water level in 2015
3	1409.43	1401.09	8.34	22.28	5.56	Low water level
4	1422.10	1400.89	21.21	42.34	13.96	Largest water-level difference between upstream and downstream in 2016
5	1430.26	1419.2	11.06	18.98	9.76	Highest upstream water level in 2016
