Flow Duration Curve Indexes

R package for compute Duration Curve Hydrological Model Indexes based on Yilmaz (Yilmaz et al., 2008) methodology. It includes duration curve plot and scatter plot to evaluate fit of daily flow series modeled series.

Requirements

Dependencies: stats, hydroGOF

Installation

You can install the development version of hydroDCindex from GitHub with this R command:

# install.packages("remotes")
remotes::install_github("Alobondo/hydroDCindex")
library(hydroDCindex)

Usage

Functions	Description
`hydroDC_Index(Q_obs, Q_sim, c_res)`	Compute Duration Curve Hydrological Model Indexes.
`Q_obs`	Column with daily observed flows.
`Q_sim`	Column with daily simulates flows.
`c_res`	Results, default 1 for indexes, 2 for duration curve values, 3 for DC plot and 4 for scatter plot.

hydroDC_Index::Q_obs Example containing observed flows.

hydroDC_Index::Q_sim Example containing simulated flows.
