Helper function: get traveltime

get_travel_time(sinusfit_sw, sinusfit_gw, retardation_factor = 1.8)

Arguments

sinusfit_sw

as retrieved by optimise_sinus_variablePeriod with surface water temperature data

sinusfit_gw

as retrieved by optimise_sinus_variablePeriod with groundwater temperature data

retardation_factor

hydraulic retardation factor (default: 2)

Value

data frame with travel times for min/max and turning points
