eflowpy 1.0.0

A Python package for estimating environmental flow requirements using hydrological methods.

eflowpy

eflowpy is a Python package for estimating environmental flow requirements using hydrological methods based on streamflow time series data. It provides a consistent and extensible interface for calculating commonly used flow-based environmental indicators.

Features

• Calculate environmental flow recommendations using:
  • Tennant Method
  • Flow Duration Curve (FDC)
  • GEFC (Generalized Environmental Flow Criteria)
  • 7Q10 Method
  • Tessman Method
• Built-in plotting support:
  • Time series plots
  • Flow threshold overlays

Installation

To install eflowpy from PyPI:

pip install eflowpy

---

How to Use

Quick Start Example

import pandas as pd
from eflowpy.hydrological.tennant import Tennant
from eflowpy.utils.data_reader import read_streamflow_data

# Load streamflow time series from file
flow_series = read_streamflow_data("gauge_12013059_daily.csv", folder="path/to/your/data")

# Run Tennant method
tennant = Tennant(flow_series)
tennant.print_summary()
result = tennant.calculate()
print(result)

# Plot bar chart and streamflow overlay
tennant.plot()
tennant.plot_with_levels()
