Why use MLU?
MLU is a Web Application for the Analysis of Aquifer Tests and the Design of Well Fields in Layered Systems delivered through a browser interface. Experience our new elegant web-based user interface. No installation needed and works on any device.

Sign-up today and start using MLU in your projects. Use 7 easy steps to characterize your project, create complex aquifer systems, well fields and calibrations based on your observations.

Areas of application
MLU is a dedicated application to analyse pumping test data and determine soil hydraulic properties. Areas of application include:

  • variable discharge tests
  • recovery tests
  • step-drawdown tests
  • complex tests in well fields
  • slug tests
  • estimating aquifer properties such as layer-by-layer transmissivity, storativity, and vertical resistance/conductance

Create and customize contour plots by choosing levels and colours. Save and load your settings for future models. Export your contours as GeoJSON for direct import into GIS.
