cania.sub.ts: Subset of the Caniapiscau River Daily Flows

In FlowScreen: Daily Streamflow Trend and Change Point Screening

Description

This data set includes a subset of the mean daily streamflow for the Caniapiscau Rivers. It includes observations from 1970-1995 (hydrologic years). The code used to subset and modify the original data is shown below.

Usage

data(caniapiscau)

Format

Formatted as a data.frame with the following columns:

• ID - Water Survey Canada Station ID

• Date - Date of observation, formatted as YYYY-mm-dd

• Flow - Mean daily streamflow, measured in m3/s

• Code - Data Quality Code

• Agency - Source Agency (Water Survey Canada)

• Year - Calendar year

• month - Calendar month

• doy - Calendar day of year

• hyear - Hydrologic year

• hmonth - Hydrologic month

• hdoy - Hydrologic day of year

# Code used to subset and modify original Caniapiscau series:
## Not run: 
data(caniapiscau)
cania.ts <- create.ts(caniapiscau, hyrstart=3)
cania.sub.ts <- subset(cania.ts, cania.ts$hyear %in% c(1970:1995))

## End(Not run)
# example use of example subset flow series
data(cania.sub.ts)
