DESCRIPTION
r.topmodel simulates TOPMODEL which is physically based
hydrologic model.
Note: (i) means input; (o) means output; (i/o) means input or output
The -i flag defines that input data are given for (i/o). Without
this flag, all input data, (i) or (i/o), should be given and intermediate
output can not be input for run.
As example, [belevation] map will be created from [elevation] and
[basin] every run. However, every [belevation] output map is the same and
this is useless process if [belevation] map is already given.
With this flag, intermediate output can be input for run. (i/o) parameters
can be affected by this flag.
The -w flag enables wide output (No limit for 80 columns output).
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
(i/o) Basin elevation map (extracted). Study basin extracted elevation
map
topidx
(i/o) 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
