SECTION 1: CONTOUR LINES AND TOPOGRAPHY (Questions 1-10)
*1. What do contour lines represent on a topographic map?**
A) Water flow direction
B) Elevation
C) Soil type
D) Vegetation density
*Correct Answer: B) Elevation**
*Rationale: Contour lines represent elevation on a topographic map.
They are critical in irrigation design to manage water flow, avoid
erosion, and ensure even distribution across varied terrains.*
**2. Closely spaced contour lines indicate what type of slope?**
A) Gentle slope
B) No slope
C) Steep slope
, 3
D) Undulating slope
**Correct Answer: C) Steep slope**
*Rationale: Contour lines spaced closely together indicate a steep
slope, while lines that are farther apart indicate a gentle slope.
Understanding slope is crucial in irrigation because it impacts water
runoff and infiltration.*
3. For hilly terrains, what irrigation practice helps reduce runoff and
improve water absorption?**
A) Increased water pressure
B) Terracing or furrows following contour lines
C) Larger sprinkler heads
D) Deeper pipe installation
Correct Answer: B) Terracing or furrows following contour lines**
*Rationale: For hilly terrains, irrigation systems may incorporate
terraces or furrows following contour lines to reduce runoff and
improve water absorption.*
**4. What is the formula for slope calculation?**
A) Run over Rise
, 4
B) Rise over Run
C) Rise × Run
D) Run - Rise
**Correct Answer: B) Rise over Run**
*Rationale: Understanding slope (rise over run) is crucial in irrigation
because it impacts water runoff and infiltration.*
**5. What is the relationship between contour line spacing and slope
steepness?**
A) Closer spacing = gentler slope
B) Closer spacing = steeper slope
C) No relationship exists
D) Wider spacing = steeper slope
**Correct Answer: B) Closer spacing = steeper slope**
*Rationale: Contour lines spaced closely together indicate a steep
slope, while lines that are farther apart indicate a gentle slope.*

**6. Contour lines are critical in irrigation design primarily to:**
A) Determine water quality
B) Manage water flow and avoid erosion
