I have two questions regarding r.sim.water.<br>
<br>
First, what are "walkers". How does the nwalk parameter affect the
analysis? It seems that with a region larger than a few million cells,
the module fails, regardless of the nwalk parameter. (I have a region
of just over 8 M cells, and even with nwalk=1, it fails with ERROR:
nwalk (7000001) > maxw (7000000)! )<br>
But when I reduce the region to < 7M cells then the nwalk parameter
helps, and the analysis succeeds.<br>
<br>
Next (asked on the grass-user list, but no response yet):<br>
<div bidimailui-direction-uniformity="ltr" dir="ltr"
style="direction: ltr;" bidimailui-generated="true">Is there a way to
create a surface flow model where the rainfall stops after a specified
time, and the model continues to run, and creates depth and discharge
rasters after the actual rainfall has stopped?
</div>
<div bidimailui-direction-uniformity="neutral"
bidimailui-generated="true"></div>
<br>
<div bidimailui-direction-uniformity="ltr" dir="ltr"
style="direction: ltr;" bidimailui-generated="true">i.e. in the case
of a short thunderstorm, I want to try to predict the extent of a flash
flood that rises, then subsides some time after the rain has ended.<br>
<br>
Thanks,<br>
