The RADGAT program was originally written in the 1980's  for mainframe computers.  An interactive version for the PC was created in the early 1990's.  The program determines discharge through canal radial gates as a function of gate opening and upstream and downstream water levels, or alternately determines the gate opening for a desired discharge.  The algorithms used in RADGAT are based on laboratory and field studies conducted by Clark Buyalski.  Research is presently underway to improve these algorithms.
