MY OWN SOFTWARE

In 1989, I purchased a popular hydraulic package from a software reseller in San Diego. The package came with a supplement, which consisted of ten programs to solve various hydraulic problems. I took the software to Santa Cruz de la Sierra, in Bolivia, and installed it in an IBM PC 286, which was used in those days. At the time, I was working on a sediment routing model for the Pirai river basin.

Great was my surprise to find one of the supplement programs all too familiar. It was a program to calculate the Modified Einstein Procedure (now available online). The form of its output left me no doubt that it was my own software, which I had developed at Colorado State University in the middle 1970s.
