AnaFlow-LOGO

Purpose

AnaFlow provides several analytical and semi-analytical solutions for the groundwater-flow equation.

Installation

You can install the latest version with the following command:

pip install anaflow

Documentation for AnaFlow

You can find the documentation under geostat-framework.readthedocs.io.

Example

In the following the well known Theis function is called an plotted for three different time-steps.

import numpy as np
from matplotlib import pyplot as plt
from anaflow import theis


time = [10, 100, 1000]
rad = np.geomspace(0.1, 10)

head = theis(time=time, rad=rad, transmissivity=1e-4, storage=1e-4, rate=-1e-4)

for i, step in enumerate(time):
    plt.plot(rad, head[i], label="Theis(t={})".format(step))

plt.legend()
plt.show()
