The Permeable Character of CSG Dams and Their Seepage Fields

Table 4

Comparison of the seepage properties of the dam body after operating for one year.

Year	Upstream water level (m)	Cutting head for antiseepage layer (m)	Cutting water-head percentage (%)	Seepage gradient		Seepage discharge (L/s)
