MLU is a Windows Application for the Analysis of Aquifer Tests and the Design of Well Fields in Layered Systems

Current release
MLU (Multi-Layer Unsteady state) can be used for drawdown calculations and inverse modeling of transient well flow (pumping tests analysis) in layered aquifer systems and stratified aquifers.

With MLU one can estimate selected aquifer parameters based on a best fit analytical solution to measured time-distance-drawdown data. The automatic curve-fitting algorithm computes optimized aquifer parameters and fitted drawdown results that are presented in graphs and ASCII-files.

Unlike other aquifer test analysis software, often supporting a wide variety of different solution types (e.g., Theis, Hantush, Neuman, Boulton, Papadopulos, Moench, Bouwer-Rice) for usually one and sometimes two aquifers, MLU is based on a single analytical solution technique for well flow that handles:

  • Layered aquifer systems, i.e. multi-aquifer systems (aquifers and aquitards)
  • and single layered (stratified) aquifers,
  • Confined, leaky and delayed yield aquifer conditions,
  • Effects of aquifer and aquitard storativities,
  • One or more pumping or injection wells,
  • Variable discharge for each well,
  • Finite diameter well screens in any selection of aquifer layers,
  • Well bore storage and skin effect for each pumping well,
  • Delayed observation well response.

Improvements in the near future
A survey among the current user base provided us with the future wishes of the users. The survey determined the overall satisfaction among users of MLU, surfaced the most wanted improvements:

  1. Improvements in user interface design
  2. Visualization & import/export to GIS software

These improvements and many others are our top priority on the roadmap. MLU is first on our list with a scheduled 2022 release of the new interface.
