r.model

NAME

r.topmodel - simulates TOPMODEL which is physically based hydrologic model
(GRASS Raster Program)

SYNOPSIS

r.topmodel [-iow] [elevation=name] [basin=name] [depressionless=name] [direction=name] [belevation=name] [topidx=name] [nidxclass=value] idxstats=name parameters=name input=name output=name [Qobs=name] [timestep=value] [idxclass=value]

Flags:

-i
Input data 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.

In 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.
-o
Overwrite outputs
-w
Wide output. No limit for 80 columns output

Parameters:

Note: (i) means input; (o) means output; (i/o) means input or output
elevation
(i) Rectangular elevation map
basin
(i) Basin map created by r.water.outlet
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.
direction
(o) Direction map with depressionless 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
nidxclass
(i) Number of topographic index classes
Default: 30
idxstats
(i/o) Topographic index statistics file
parameters
(i) TOPMODEL parameters file
input
(i) Rainfall and potential evapotranspiration data file
output
(o) Output file
Qobs
Observed Q file. Compare Qt with Qobs and calculate model efficiency
timestep
OPTIONAL output for given time step
idxclass
OPTIONAL output for given topographic index class
