Trehafod: Trehafod River Flow Data

Description

Annual maximum river flow data from the Trehafod gauging station in Wales, UK. This dataset is commonly used for demonstrating non-stationary extreme value analysis methods.

Usage

Trehafod

Format

A data frame with 53 rows and 2 columns:

Year

Year of observation (integer, 1968-2021)

r1

Annual maximum river flow in cubic meters per second (m^3/s)
