SEEPAGE

Which are conditions that create seepage action?

• Water head difference

• The shape of seepage area

• The medium that contains pores cracks or discontinuity

• The permeability of seepage area

"Homogenous earth dam" indicate

• Zoned embankment type that contains different type of soil

• Embankment dam that are made of the same type of earth at every point in the body

• Non-homogenous type that include more than one type of material

• Diaphragm type that have concrete inside the earth body

The action of water particle movement through porous medium due to head water difference is called

• Infilteration

• Percolation

• Seepage

• hydraulic conductivity

Which of the following parameters show the permeability property of earth?

• permeability factor

• flow velocity

• unit discharge

• Hydraulic conductivity

What are TRUE about the flow net properties?

• The water particle acceleration vector is tangent to the flow line

• The space between two adjacent potentials is called the drop

• Potential lines and flow lines create a net of curved-linear squares

• All the above

What are the seepage problem results?

• Seepage gradient J

• Hydraulic velocity (m/s)

• Total water head h (m)

• Flow rate q (m3/s.m)

Propose methods to solve the seepage problems

In the context of earth dams, what does the term 'pore water pressure' refer to?

answer choices

• The pressure caused by the weight of the dam

• The pressure from water flowing over the dam

• The pressure of water at the surface of the dam

• The pressure exerted by water within the soil pores

What are the energy components that the total water head (ht) include?

• Molecular energy

• Pressure head

• Elevation head

• Velocity head
