rise: Water Table Rises

In USGS-R/DVstats: Functions to manipulate daily-values data

Water Table Rises

Description

Identify groundwater rises based on hydrographs of daily values.

Usage

rise(x, Dates, Start = NULL, End = NULL, MPelev = NULL,
  STAID = "Unknown")

Arguments

x	the daily value data to be summarized. Missing values are not permitted within the time specified by Start and end.
Dates	the date for each x, should be of class "Date." Missing values are not permitted.
Start	the start date for the analysis, can be either a character string or class "Date."
End	the end date for the analysis, can be either a character string or class "Date."
MPelev	the measuring point elevation. Required if x is a depth below land surface or measuring point.
STAID	the station identifier for the data.

Value

An object of class "rise" and inherits class "data.frame" of the selected data, a data frame of the recession information, and other information about the analysis.

Note

Rutledge (2002) describes the rise methed for computing recharge. the method is a variation on the water-table fluctuation method that assumes no recession.
