Major Software

In addition to educational software, I have developed a user friendly versions of the lumped parameter model (Ling and E-Kadi, 1998, El-Kadi and Ling, 1999), and the stochastic generator program (El-Kadi and Williams, 2000), which are available free of charge. I developed user interfaces for the models NETPATH and SOLMINEQ for the courseware authored by Aggarwal et al. (2004).
