Flow Characteristic (FC) Programme for Aquifer Test Analysis (Free)

Developed by Prof Gerrit van Tonder, Dr Modreck Gomo, and Mr Fanie de Lange

In South Africa, the main aim of pumping tests is to estimate what we call sustainable yield of a borehole. The sustainable yield is defined as the rate at which the borehole can be operated for a long time (e.g. two years) without reaching a specified drawdown level (in other words, the position of the main water strike in a fractured-rock aquifer), including the influence of boundaries and other boreholes.

We call this programme the FC Programme (Flow Characteristic Programme), and methods include the following:

  • the Derivative Method;
  • the Barker Fractal method; and
  • the Cooper-Jacob method.

One can also analyse step drawdown tests, slug tests, etc. This programme works in Excel 2010.
