A nonlinear model is developed for allocating treatment requirements along a stream so as to meet stream dissolved oxygen standards at each point in the stream while minimizing the total annual cost of all discharging activities. An application of the model to several reaches of the Upper Hudson...

A simple primal solution method for geometric programming is proposed. The method exploits the proximity of geometric and linear programming and is easy to implement by anyone having a linear programming code. Some examples and computational experience are given.
