Dams
Within Dams, the answer "By temporarily storing high flows" is associated with which tested detail?
A. sedimentation
B. flood control
C. spillway
D. arch dam
Correct Answer: B
The tested detail is "flood control". Reservoir operation can attenuate flood peaks.

Dams
Within Dams, the answer "It mainly regulates and diverts river flow with gates" is associated with which tested detail?
A. main purpose
B. barrage distinction
C. spillway
D. sedimentation
Correct Answer: B
The tested detail is "barrage distinction". Barrages raise water level for diversion but usually provide far less storage than major dams.

Dams
Within Dams, the answer "Valley abutments" is associated with which tested detail?
A. sedimentation
B. arch dam
C. flood control
D. catchment
Correct Answer: B
The tested detail is "arch dam". The curved structure carries force into strong rock on the sides of a narrow valley.

Dams
Within Dams, the answer "By its own weight" is associated with which tested detail?
A. live storage
B. earthfill
C. gravity dam
D. sedimentation
Correct Answer: C
The tested detail is "gravity dam". A gravity dam relies on its mass to resist the horizontal force of stored water.

Dams
Within Dams, the answer "Compacted soil and rock" is associated with which tested detail?
A. flood control
B. gravity dam
C. earthfill
D. main purpose
Correct Answer: C
The tested detail is "earthfill". Earth-fill dams use compacted natural materials rather than a solid concrete wall.

Dams
Within Dams, the answer "Sedimentation" is associated with which tested detail?
A. hydropower
B. sedimentation
C. dam safety
D. flood control
Correct Answer: B
The tested detail is "sedimentation". Silt carried by rivers settles in reservoirs over time.
CSS - PMS - CCE - PCS - Pakistan Affairs (P.A)
Dams
Within Dams, the answer "Reservoir" is associated with which tested detail?
A. dead storage
B. irrigation
C. reservoir
D. sedimentation
Correct Answer: C
The tested detail is "reservoir". A reservoir stores water impounded by a dam.
CSS - PMS - CCE - PCS - Pakistan Affairs (P.A)
Dams
Within Dams, the answer "Safely release excess water" is associated with which tested detail?
A. reservoir
B. spillway
C. flood control
D. gravity dam
Correct Answer: B
The tested detail is "spillway". Spillways protect dams from overtopping during high inflows.
CSS - PMS - CCE - PCS - Pakistan Affairs (P.A)
Dams
Within Dams, the answer "Water drives turbines connected to generators" is associated with which tested detail?
A. sedimentation
B. reservoir
C. hydropower
D. spillway
Correct Answer: C
The tested detail is "hydropower". Potential energy of stored water is converted to mechanical and then electrical energy.
CSS - PMS - CCE - PCS - Pakistan Affairs (P.A)
Dams
Within Dams, the answer "Store water for later use" is associated with which tested detail?
A. dead storage
B. sedimentation
C. main purpose
D. barrage distinction
Correct Answer: C
The tested detail is "main purpose". Storage dams regulate seasonal river flows for irrigation, water supply, power and flood control.

Dams
Which pairing is correct for the "live storage" aspect of Dams?
A. live storage — Safely release excess water
B. live storage — By its own weight
C. live storage — By temporarily storing high flows
D. live storage — Usable reservoir volume between operating levels
Correct Answer: D
The correct match is "live storage — Usable reservoir volume between operating levels". Live storage can be released for irrigation, water supply or power generation.
