flow-modnum 0.0.20

Flow Hydro Consulting's numerical modeling group Python library.

flow-modnum

Python library with utilities created for Flow Hydro Consulting numerical modeling group.

Introduction

flow-modnum is a library with utilites created for Flow Hydro Consulting numerical modeling group. The utilites were built to plot results from MODFLOW models, such as water levels, concentrations, properties, among others. flow-modnum supports MODFLOW-USG. Results from model's are generated using PEST's Groundwater Utilities (https://pesthomepage.org/programs)

Questions

Do not open issues for general support questions. We want to keep GitHub issues for bug reports and feature requests. General support questions are better answered in the Discussions on the flow-modnum GitHub repository. If using Stack Overflow, questions should be tagged with tag flow-modnum.

To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow or the MODFLOW google group.
