[GRASS-user] r.sim.water crashes (repost)

[Hanlie Pretorius]

Hi,

This is a repost since I got no reaction the previous time. I'm not
sure if it is because people can't help. Is it ok to contact the
authors at the bottom of the r.sim.water page if no one on this list
can help me?

I'm working on Windows XP SP3 and Grass 6.4.0RC6. When I try to run
r.sim.water according to the example on page 163 in the book "Open
Source GIS a GRASS GIS approach" (3rd Ed.), I get one of those Windows
errors that want to 'tell Microsoft about this problem'.

The details of the error report says:

AppName: r.sim.water.exe         AppVer: 0.0.0.0         ModName:
libgrass_gis.6.4.0rc6.dll
ModVer: 0.0.0.0  Offset: 0001a3f7

The first module listed in the detailed technical report is
r.sim.water.exe. Many modules follow after that.

The book uses the North Carolina example datasets and the steps are as follows:

g.region=rural_1m res=2 -p

r.mapcalc man05=0.05
r.mapcalc infil0=0.
r.mapcalc rain50mmhr=50

v.surf.rst -d input=elev_lid792_bepts layer=0 elev=elev_lid792_2m
slope=dx_2m aspect=dy_2m ten=15 smooth=1.5 segmax=25 npmin=100

r.sim.water -t elevin=elev_lid792_2m dxin=dx_2m dyin=dy_2m
rain=rain50mmhr infil=infil0 manin=man05 depth=wdp_2m disch=disch_2m
nwalk=400000 niter=500 outit=20 hmax=0.2 halpha=8.0 hbeta=1.0

I have tried these steps on two different computers and get the same
error. I have also tried the example on the manual page of r.sim.water
with the same result.

Can someone perhaps suggest a fix?

Thanks
Hanlie
