Question 3 NECO • 2018 • GEOGRAPHY • objective

The average annual rainfall in a region is 1200 mm. Climate‑change projections indicate a 12 % increase in rainfall over the next decade. The region's drainage system can safely convey up to 1300 mm of rainfall per year without flooding. A flood‑mitigation scheme can be activated only if the projected rainfall exceeds 1250 mm; when activated it reduces the effective rainfall by 5 %. Determine whether the region will be at risk of flooding in ten years, and state the effective rainfall after mitigation (if any) and the amount by which it is below or above the drainage capacity.

Answer Options

A. No flooding risk; effective rainfall = 1254 mm, which is 46 mm below the drainage capacity
B. Flooding risk; effective rainfall = 1344 mm, which is 44 mm above the drainage capacity
C. Flooding risk; effective rainfall = 1411.2 mm, which is 111.2 mm above the drainage capacity
Correct Answer D. No flooding risk; effective rainfall = 1276.8 mm, which is 23.2 mm below the drainage capacity
Correct Answer
D
Correct Option:
No flooding risk; effective rainfall = 1276.8 mm, which is 23.2 mm below the drainage capacity
