Trend of Annual Discharge Minimum Values since begin of Measurements

Description

Trend of Annual Discharge Minimum Values since begin of Measurements

Usage

Qmin_trend(data, station, mod = 1)

Arguments

data	list; contains all stations that the discharge analysis should consider. List can be created by grdc_list. Each entry of the list contains the existing discharge measurements (as numeric) and the corresponding dates (as character) for the station.
station	character; Name of the Station e.g. "COCHEM" - must be named equally like list entry in data.
mod	numeric; possible input: 1,2,3. default value: 1; output of both: zyp.trend.vector, lm. Defines the way to calculate intercept and slope. For mod=2 zyp.trend.vector with PreWhitening by "yuepilon-method" is used. Sen-Slope-Approach used to define direction of the trend and the significance is determined by Kendall's P-Value computed for the final detrendet time series. For mod=3: lm with a least squares approach is used.

Examples

## Not run:  Qmin_trend(mosel, "COCHEM")
