General Questions in Raven

[Symona]

I think you can put whatever number and it would not have an effect the process (given you aren't using other VIC processes). Let me know if having random values of the three terms messes things up.

Regarding this issue it seems that the soil properties VIC_ALPHA, VIC_ZMAX and VIC_ZMIN do not play a significant role as long as I do not set them zero. However there seems to be some connection because setting them 0 messes things up. Could someone please look at the connection a little closer?

Thanks a lot!

Hi Symona,

That's now in our to do list for next update.
Hopefully it gets fixed by the next release.

Thank you

Hi Rob,

Thank you for the help. It is working.

Now I am having errors on:

annual.peak.event(sim,obs,add.r2=F)
Error in as.POSIXlt.numeric(zoo::index(x)) : 'origin' must be supplied

annual.peak.event.error(sim,obs)
Error in as.POSIXlt.numeric(zoo::index(x)) : 'origin' must be supplied

annual.peak.timing.error(sim,obs)
Error in as.POSIXlt.numeric(zoo::index(x)) : 'origin' must be supplied

flowdurcurve.plot(myhyd$sim, prd='1999-10-01/2007-09-30',seasonal=F)
Error in as.POSIXlt.default(x, tz = tz(x)) :
do not know how to convert 'x' to class “POSIXlt”

Your help is highly appreciated

Thank you
Elizabeth

Hi Elizabeth

This looks like a time series formatting error in the input data. Can you confirm that the sim and obs that you are supplying are being read in from file using the hyd.read function OR are formatted using the xts package? If within R, you use

Code: Select all

class(sim)

it should show up as class xts. If not then please format your data using the xts package. Here is a link as an example of formatting something into an xts format if needed. https://stackoverflow.com/questions/47143447/r-list-of-time-series-dates-need-to-break-out-in-order-to-perform-arima-style/47144634#47144634

Hi Rob,

class(sim)
[1] "xts" "zoo"

yes, simulated from hyd.read function

hy<-hyd.read("run1_Hydrographs.csv")

Thank you
