Write an initial conditions (rvc) format file for Raven, with the calculated reservoir stages written in.
rvn_rvc_res(ff, initial_percent = 0, output = "initial_res_conditions.rvc")full file path to the reservoir information file
an optional double for percentage of maximum stage to use as initial condition; default 0.0
file rvc lines are written to (default: initial_res_conditions.rvc)
return TRUE if the function is executed properly
Writes an initial conditions format file for Raven with the relevant initial reservoir stages. This file can be used directly as the model rvc file, or one may copy and paste the information into a separate rvc file for use (i.e. if there is other information to be included in the model rvc file).
The supplied file in ff should be a csv file consistent with the format from the Raven-generated ReservoirStages.csv file. External observations of reservoirs may be used given that the csv file follows the same format.
The initial_percent must be between 0 and 1, so that the initial stage is not less than the dry stage or greater than the maximum.

ff <- system.file("extdata","ReservoirStages.csv", package="RavenR")
