loss {RHMS}

Excess rainfall computation

Description

this function provides methods (e.g. "horton" and "SCS") to compute loss and direct runoff depths

Usage

loss(precipitation,lossMethod,lossParams)

Arguments

precipitation

a vector of precipitation time series(mm)

lossMethod

a string including the type of lossMethod: "SCS" and "horton". default to "SCS" method

lossParams

a list of parameters associated to the selcted type of lossMethod:

• the curve number, CN, and imperviousness in precentage for "SCS" method

• f0, f1, k for "horton" method

• timeInterval: the interval of each steps in seconds needed for "horton" method

Value

a dataframe: including precipitation, loss, and exess rainfall depth
