reachRouting: channel routing computation

Description

base function for routing floods using parameteric Muskingum and muskingum-cunge techniques.

Usage

reachRouting(inflow,routingMethod="muskingum",
             routingParams=list(k=3,
                                x=0.2,
                                bedWith=NULL,
                                sideSlope=2,
                                channelSlope=NULL,
                                manningRoughness=0.025,
                                riverLength=NULL),
             simulation=c(interval=3600*1,period=NA))

Arguments

inflow

a vector : direct inflow time series (cms)

routingMethod

a string: the type of channel routing method: 'muskingum' or 'muskingumcunge'

routingParams

a list : parameters associated to the routingMethod: 'k' and 'x' for 'muskingum', 'bedWith' (m), 'sideSlope' (m/m), 'channelSlope' (m/m), 'manningRoughness', 'riverLength' (Km) for 'muskingumcunge'

simulation

a vectors: number of simulation time steps and the simulation period in seconds.

Value

a data.frame: including inflow time series routing resaults and simulation details
