title: Stochastic Inversion of Transient Electromagnetic Data to Derive Aquifer Geometry and associated Uncertainties

description: Context

This repository contains all the data, scripts, and libraries needed to reproduce the results (except for the QGIS map) from the article "Stochastic Inversion of Transient Electromagnetic Data to Derive Aquifer Geometry and Associated Uncertainties" by Lukas Aigner, Hadrien Michel, Thomas Hermans, and Adrián Flores Orozco.

Reuse instructions

Functions and classes needed to run the scripts are located in the modules subfolder. Please find the scripts to reproduce the figures of the manuscript within the project folder. The scripts are configured to add a relative import path to os.sys

To build the Python environments:There are several Conda environments (*.yml) provided; the correct environment to use depends on the use case (i.e. which parts of the provided code to execute).For everything related to pyBEL1D please use the bel1d environment, for the sensitivity analysis please use the salib_tem.yml file, while all the other scripts can be run using the empypg.yml.

Special thanks

This work would not have been possible without many other open-source libraries, so please also have a look at the following repositories and consider citing the corresponding articles:

title: Mindestlöhne

description: Data refer to the monthly national minimum wages, established every half year (1st January and July). Minimum wages may be determined by hourly or weekly rates in certain countries; these are converted into monthly rates. The minimum wage agreement process, its application and enforcement may vary by country. Minimum wages are gross amounts, i.e. before deduction of income tax and social security contributions payable by the employee.
description: Daten beziehen sich auf die monatlichen nationalen Mindestlöhne, die halbjährlich (am 1. Januar und am 1. Juli) festgelegt werden. Da der grundlegende nationale Mindestlohn auch als Stunden- oder Wochensatz festgelegt sein kann, werden diese in Monatssätze umgerechnet. Das Verfahren zur Vereinbarung von Mindestlöhnen sowie deren Anwendung und Durchsetzung können je nach Land unterschiedlich sein. Mindestlöhne sind Bruttobeträge, d. h. vor Abzug der vom Arbeitnehmer zu zahlenden Einkommensteuer und Sozialversicherungsbeiträge.
description: Les données se réfèrent aux salaires minima mensuels nationaux, établis semestriellement (au 1er janvier et au 1er juillet). Dans certains pays le salaire minimum national n'est pas fixé sur une base mensuelle mais sur une base horaire ou hebdomadaire; ceux-ci sont convertis en salaires mensuels. Le processus de négociation des accords sur le salaire minimum et son application peuvent varier selon les pays. Les salaires minima sont des montants bruts, c'est-à-dire avant déduction de l'impôt sur le revenu et des cotisations de sécurité sociale.
