Calculating catchment characteristics

A nice paper I came across recently (Latron et al., 2008), uses some simple indicators to determine rainfall–runoff relationship for a catchment. The R code for deriving them from time series is very simple and left as an excercise.


 * Rainfall depth (mm)


 * Mean rainfall intensity (mm)


 * Maximum rainfall intensity (mm)


 * Storm-flow (mm)


 * Storm-flow coefficient (%)


 * Base-flow specific discharge (at the start of the flood) (l/s/km2)


 * Peak-flow specific discharge (l/s/km2)


 * Specific discharge increment (l/s/km2)
