Study Figure 1, which shows storm hydrograph data for an urban catchment and a nearby rural catchment after the same rainstorm.
Figure 1: Storm hydrograph data for two catchments after the same rainstorm
Characteristic | Urban catchment | Rural catchment |
|---|---|---|
Lag time (hours) | 2 | 9 |
Time to peak (hours) | 3 | 11 |
Peak discharge (cumecs) | 95 | 40 |
Base flow (cumecs) | 8 | 18 |
