Practice objective / multiple choice question 42 from the 2020 Waec Model Questions Vol1 Geography examination.
Three river basins have the data shown: - Basin X: annual rainfall 1,400 mm, catchment area 2,000 km², average discharge 45 m³/s. - Basin Y: annual rainfall 1,100 mm, catchment area 1,500 km², average discharge 30 m³/s. - Basin Z: annual rainfall 1,600 mm, catchment area 2,500 km², average discharge 55 m³/s. Runoff depth (mm) for a basin is calculated as: \[\text{Runoff depth}=\frac{\text{Discharge}\times\text{seconds in a year}}{\text{Area (m²)}}\times1000\] (where 1 km² = 1,000,000 m² and a year has 31,536,000 seconds). Which basin has the greatest runoff depth per unit area? Provide the basin name.
