A simple simulated dataset for use in testing hydrological models.

HydroTestData

Format

A zooreg object with 730 (365 * 2) time steps.

There are three columns, P (simulated areal rainfall, mm/day), E (simulated temperature, degrees Celcius) and Q (simulated streamflow, mm/day).

Details

Rainfall (P): a regular series of impulses (every 20 time steps). Each of these pulses have a value of 5, except one which has a value of 20.
Temperature (E): a sine wave ranging from 0 to 30.
Streamflow (Q): proportional to the square of rainfall and inversely to temperature, then filtered with a second-order autoregressive filter.
