DESCRIPTION
r.topmodel simulates TOPMODEL which is a physically based
hydrologic model.
Note: (i) means input; (o) means output; (o/i) means input or output
The -i flag defines that input data are given for (o/i). Without
this flag, all input data (i) and intermediate output (o/i) should be given
and intermediate output can not be input for run.
For example, [belevation] map will be created from [elevation] and
[basin] in every run. However, every [belevation] output is the same and
this is useless process if [belevation] map is already given.
With this flag, intermediate output can be input for run. (o/i) parameters
will be affected by this flag.
Selected Parameters:
depressionless
(o) Depressionless elevation map
This can be omitted if [elevation] map is already depressionless map.
If this is given, [depressionless] map will be used as [elevation] map.
belevation
(o/i) Basin elevation map (extracted). Study basin extracted elevation
map
topidx
(o/i) Topographic index ln(a/tanB) map (extracted). Study basin
extracted topographic index map
Qobs
Observed Q file. Compare Qt with Qobs and calculate model efficiency
