PUMPIT-MJ (2014)
Estimation of hydraulic parameters from pumping tests. MJ-Pumpit is a Graphical User Interface for MariaJ code (hereinafter MJ) which simplifies the data handle and the model selection needed to execute MJ code (Carbonell et al., 1997). Thus, MJ-Pumpit has been developed as a MS Excel Add-in. The use of MS Excel spreadsheets as platform is due to: (a) ensure a portable and handled easily format; (b) easy performing of data queries, analysis and plots; (c) its user-friendly interface to create numerical and statistical computations; (d) user can apply special tools to fix contradictory data storage or check potential mistakes; (e) most of hydrogeologist utilize fluently these type of programs, among others. In this way, MJ-Pumpit has available many of the MS Excel tools to analyze and plot input and output data to ease the pumping test interpretation with analytical models for different aquifer test included in MJ code. MJ-Pumpit is composed of different commands that facilitate the interpretation process of pumping test interpretation and allow:
- Error typing avoidance during the field data insertion process.
- Field data quality analysis improvement thanks to the wide possibilities of data analysis of MS Excel before executing the code.
- Ensuring an appropriate selection of the conceptual model thanks to diagnostic plots.
- The integration of different aquifer scenarios by different methodologies of pumping test analysis: Theis (1935), Hantush (1956), Barker (1988) and Hseih and Neuman (1985a). Furthermore, other characteristics are available like edges (recharge or waterproof), pumping well loss (linear and quadratic), double porosity, wellbore pumping storage and anisotropy parameters, among others.
- Results display from the iterative process through automatically generated reports and graphical plots of fitted and measured values. Their formats can be changed as user wants with MS Excel capabilities.
- MJ-Pumpit can be used in six different languages.
