These problems focus on analyzing pumping‑test and slug‑test data. Curve‑matching or straight‑line interpretations can be used as appropriate to analyze time‑drawdown data. Data can be plotted by hand on graph paper supplied in Box 1, using spreadsheet programs (e.g., Excel®,) open‑source solution methods, or commercially available software packages. In some cases, it may be helpful to copy figures of type curves presented in this book into a program (e.g., PowerPoint®; Excel®) that allows the user to stretch axes to match plots of time‑drawdown data you have prepared. Remember when manually inspecting type curves and data sets, the graph scales must match.

Free demo versions of the three most popular hydraulic testing software may also be applied as appropriate to complete these problems, including

Mastering the use of one or more of these programs takes time. Help files and documentation are available on the websites.

We recommend that the reader first use a manual curve‑matching method as described in the previous sections before numerical modeling. This aligns with our goal of having the hydrogeologist understand the foundational principles used in hydraulic‑test analyses. After completing a standard curve‑matching solution, a software‑generated match can be derived. When both methods are executed, the results should be compared and contrasted. Box 11 provides AQTESOLV solutions for Problems 1, 2, 3 and 5 and compares them to hand‑matched results.
