Answer
One reason evident on the topographic map is the presence of gentle slopes. This allows for a smoother and more efficient path for the railway line, minimizing the need for extensive engineering solutions.
Step 2
Generally, Ladysmith receives limited rainfall. Give TWO reasons evident on the map to support the statement.

Answer
The presence of numerous dams indicates that water is scarce, requiring storage solutions.
Cultivated lands along riverbanks imply that the area depends on irrigation rather than consistent rainfall.
Step 3
Suggest ONE piece of topographic map evidence that indicates the discharge of the Klipriver fluctuates/changes during the certain times of the year.

Answer
The presence of non-perennial watercourses along the Klipriver suggests that the discharge fluctuates, indicating it may not flow continuously throughout the year.
Step 4
In the South Western part of the mapped area, there is evidence of the frequency of veld fires. How do Ladysmith residents deal with the threat of Veld fires? Use ONE map evidence to support your answer.

Answer
The presence of firebreaks on the map indicates how residents manage the threat of veld fires by creating barriers to slow down or stop the spread of flames.

Answer
The tributaries join the river at acute angles, suggesting a southeast flow direction.
The elevation contours indicate a drop in height towards the southeast, further supporting the flow direction.
Step 8
Determine the stream order of the Bell's Spruit at point W, in block A2 on the topographic map.

Answer
The stream order of the Bell's Spruit at point W is classified as a 3rd order stream, as it branches from two 2nd order streams.

Answer
The street pattern at Hillside is identified as a gridiron pattern, characterized by intersecting streets arranged in a systematic layout.
Step 10
Suggest ONE physical factor evident on both topographic and orthophoto maps that influenced the choice of street pattern in QUESTION 3.6.1 above.

Answer
The area is relatively flat, making it conducive for a gridiron street layout without significant elevation changes.

Answer
Advantage: It is easy to find your way around due to the predictable grid layout.
Disadvantage: The layout can lead to traffic congestion, especially at major intersections.
