Six Mathematica notebooks containing solutions for the response of aquifers to periodic forcing

This dataset contains six Mathematica notebooks (.nb files, Version 13.3.0) and six printouts of those notebooks (.pdf files) corresponding to Examples 1 to 6 in a paper published by Townley (1995).

An early version of Mathematica was used during preparation of the original paper. In 2021, starting with a set of old .ma files, the six solutions were redeveloped, verified and extended. No errors were found in the mathematical solutions presented by Townley (1995), apart from a missing subscript. However, more than a dozen errors were found in Figures in the original paper, including one due to an error coding a function that was evaluated and plotted, incorrect axis labels, incorrect labels on curves and incorrect Figure captions.

A decision was made to prepare an Addendum to the original paper. The author is grateful to the Editor of Advances in Water Resources (AWR), Prof. Graham Sander, for agreeing to publish an Addendum 28.5 years after initial publication (Townley, 2023a). His decision was based partly on the fact that when old issues of AWR were scanned and made available online, a number of 3D graphics became black, so that readers of the paper online have for many years been unable to see and visualise the original results. High quality 3D graphics are now available using the Mathematica notebooks provided here, in this dataset (Townley, 2023b).

Export of graphics for publication:
The Mathematica notebooks display graphics inside the notebooks. In order to prepare graphics for the new Addendum, plots were exported directly to .svg files (not acceptable for publication at this time), .eps files and .tif files (at 1000 dpi). The Background was set to "None", axes and frames were set to black using Directive[Black], and some labels were deleted. To help others who use Mathematica to produce high quality graphics for publication in future, this dataset also includes HowToExportGraphicsFiles.txt, which shows how to export two graphics files for Example 3.

本数据集包含6份Mathematica（Mathematica）笔记本文件（.nb格式，版本13.3.0），以及对应Townley（1995）发表论文中示例1至6的6份笔记本打印件（.pdf格式文件）。

原始论文撰写期间使用了早期版本的Mathematica。2021年，研究团队以一组旧的.ma格式文件为基础，重新开发、验证并拓展了这6组求解结果。Townley（1995）给出的数学求解过程仅存在一处下标遗漏的小问题，未发现其他错误。但原始论文中的插图存在十余处错误，包括被求值并绘图的函数编码错误、坐标轴标签错误、曲线标注错误以及插图说明错误。

团队决定为原始论文编制一篇补遗。作者感谢《Advances in Water Resources (AWR)》编辑Graham Sander教授同意在初始发表28.5年后刊发该补遗（Townley, 2023a）。该决定的部分依据是：当《AWR》过刊被扫描并上线后，多篇论文中的3D图形变为黑色，致使多年来线上读者无法查看和可视化原始结果。本数据集提供的Mathematica笔记本现已可生成高质量3D图形（Townley, 2023b）。

导出用于出版的图形：
Mathematica笔记本可在笔记本内部显示图形。为制备新补遗所需的图形，研究团队直接将绘图导出为.svg格式文件（目前暂不接受用于出版）、.eps格式文件以及1000 dpi分辨率的.tif格式文件。将背景设置为"None"，使用Directive[Black]将坐标轴与边框设置为黑色，并删除了部分标签。为帮助其他使用Mathematica为未来出版制作高质量图形的用户，本数据集还包含HowToExportGraphicsFiles.txt文件，该文件演示了如何为示例3导出两份图形文件。
