process representation overview tables - links to more specific pages about individual processes?
Canopy interception and evaporation vs throughfall
| Process & algorithm description | WRSM-Pitman (Sami GW) | SPATSIM Pitman (Hughes GW) | ACRU (ACRU4) | SWAT (ArcSWAT2012) | MIKE-SHE semi-distributed | MIKE-SHE fully distributed |
|---|---|---|---|---|---|---|
| General inputs | Rain, cover properties | Rain, cover properties | Rain, PET, cover properties, canopy storage (state) | not explicit – part of ‘initial abstraction’ calculation, see infiltration & surface runoff below | Rain, PET, cover properties, canopy storage (state) | Rain, PET, cover properties, canopy storage (state) |
| Specific inputs | Rainfall, max interception | Rainfall, max interception | Rainfall, canopy storage (state), max interception (or LAI), PET | Rainfall, canopy storage (state), LAI, interception coefficient, PET | Rainfall, canopy storage (state), LAI, interception coefficient, PET | |
| Function type | exponential & threshold | exponential & threshold | threshold | threshold | threshold | |
| Thresholds? | yes: interception capacity (calculated) | yes: interception capacity (calculated) | yes: interception capacity (input) | yes: interception capacity (input) | yes: interception capacity (input) |
