baseflow 0.0.9

A python package for baseflow separation

baseflow

An open-source Python package for baseflow separation 🔥

⚡  Usage

Install

pip install baseflow

Example

import baseflow
import pandas as pd

df = pd.read_csv(baseflow.example, index_col=0)
df_sta = pd.DataFrame(data=[[30, -28.4, 659], [-109.4, 33, 1611]],
                      index=df.columns, columns=['lon', 'lat', 'area'])
dfs, df_kge = baseflow.separation(df, df_sta, return_kge=True)
print(f'Best Method:\n{df_kge.idxmax(axis=1)}')

📌  Todo

Nolinear reservoir assumption

• Implement the nolinear reservoir assumption from the paper
• Employ a time-varing recession coefficiency for baseflow separation

Applicable to other time scales

1. The current version only applies to the daily scale
2. The package needs to be updated to support hourly baseflow separation
