instantiates an object from class of createSubbasin
createSubbasin(name,precipitation,
inflow,Area,delayInflow,downstream,
transformMethod,lossMethod,BFSMethod,UH,
abstractionParams,transformParams,lossParams,BFSParams)
(optional): a string: the name of sub-basin to be instantiated
a vector : a time series of precipitation hytograph (mm)
(optional): a vector of direct inflow rather than flows comming from upstream (cms)
the area of basin (Km^2)
(optional): an integer presenting the time steps to delay direct/lateral inflow time series
(optional): an object from either of classes: createDiversion
, createReservoir
, createSubbasin
, createJunction
, createReach
.
a string: the type of transformation method. Available types: "SCS"
, "snyder"
, and "user"
for user defined unit hydrograph. default to "SCS"
a string: the type of loss method. Available types: "SCS"
and "horton"
a string: The method of base flow separation. Available methods: 'nathan'
, 'chapman'
, 'eckhardt'
, 'recession'
a data.frame: including the ordinates of user UH. the HU first collumn indicates time (Hr) and second collumn include flow rates (cms)
