Runoff#

runoff loads surface-runoff forcing or hydrological diagnostics. It should not be confused with groundwater discharge or drainage-package fluxes.

Accepted sources#

  • custom

  • sim2

[[data.runoff.sources]]
source = "sim2"
extent = "watershed"

Check period coverage, units, and semantic meaning before comparing runoff with simulated groundwater discharge.

Visual check#

Local custom runoff and recharge source series

Fig. 174 Runoff should be read as a forcing or diagnostic source, not as simulated groundwater discharge. The paired custom figure makes that distinction visible by keeping the source chronicle separate from any solver response.#

Runoff Source: custom#

Use source = "custom" for local runoff fields or time series.

[[data.runoff.sources]]
source = "custom"
path = "data/runoff/runoff.nc"
source_unit = "mm/day"

Check the semantic meaning of the runoff product before using it in water balance reasoning.

Runoff Source: sim2#

Use source = "sim2" to retrieve SIM2 runoff fields.

[[data.runoff.sources]]
source = "sim2"
extent = "watershed"

Use the climatic summary for data checks and keep runoff distinct from modeled drainage or groundwater discharge.
