 I want to know how to control algorithms like fitbyoptim ,fitbyDream in hydromad?The NSE values comes out to be negative?do we have to fix maximum number of iterations or some other argument

[Alex]

The documentation for these functions tells you how to control the fitting procedure (e.g. help('fitByOptim')). From there you can see the samples argument, which is the number of random parameter sets that will be sampled, and the control argument which is passed onto the fitting algorithm. In case you haven't, I'd recommend looking at the tutorial which covers a lot of the hydroid fundamentals (https://hydromad.github.io/articles/tutorial.html)

Thank you very much for the helpful reply.Will no. of samples be equal to parameters to be calibrated in the model?How to set control argument?

Which routing module should we used for sac-sma model without snow?I am using model  as

modCz1 <- hydromad(Data,
                   sma="sacramento", uztwm=c(1.0,150.0), uzfwm=c(1.0,150.0), uzk=c(0.1,0.5),
                   pctim=c(0.0,0.1),adimp=c(0.0,0.40), zperc=c(1.0,250.0), rexp=c(0.0,5.0),
                   lztwm=c(1.0,500.0), lzfsm=c(1.0,1000), lzfpm=c(1.0,1000), lzsk=c(0.01,0.25),
                   lzpk=c(0.0001,0.25),
                   pfree=c(0.0,0.6))

I am not getting output flow from it?How to fix routing part in it???

Hi Mehnaz,

You already have the output from the SMA in U, but at the moment you have it set up with parameter ranges. You can use any routing, including none, that is the whole idea from hydromad. But the simplest routing is expuh, which is an exponential bucket (a linear reservoir).

Thanks for the quick reply... Can we do hymod in hydromad? It's sma module isn't available in hydromad.

See answer from Alex earlier. No, not at the moment. But hydromad is open source so you can write your own module.

Thanks 

Willem Vervoort for you helpful answers.I have now used LeakyExpStore for routing and it worked well.
