       BFSParams=list(alpha=NULL,BFI=NULL,k=NULL))

Arguments

name

(optional): a string: the name of sub-basin to be instantiated

precipitation

a vector : a time series of precipitation hytograph (mm)

inflow

(optional): a vector of direct/lateral inflow (cms)

Area

the area of basin (Km^2)

delayInflow

(optional): an integer presenting the time steps to delay direct/lateral inflow time series

downstream

(optional): an object from either of classes: createDiversion, createReservoir, createSubbasin, createJunction, createReach.

transformMethod

a string: the type of transformation method. Available types: "SCS", "snyder", and "user" for user defined unit hydrograph. default to "SCS"

lossMethod

a string: the type of loss method. Available types: "SCS" and "horton"

BFSMethod

a string: The method of base flow separation. Available methods: 'nathan', 'chapman', 'eckhardt', 'recession'

UH

a data.frame: including the ordinates of user UH. the HU first collumn indicates time (Hr) and second collumn include flow rates (cms)

abstractionParams

a list: including parameters of simple surface and simple canopy methods.

  • canopyAbstaction depth of canopy abstraction in (mm)
