Modification on the Schofield stochastic model for estuaries

Now with the continuing development of computers, more detailed and complex mathematical models are being developed for the use of modeling estuaries. Schofield and Krutchkoff developed a one dimensional stochastic model to predict the concentration of twelve components, five biological and seven chemical.

It was criticized because all the components had to be included in the model in order for its operation when in fact one only wanted to study a subset of them. It was the object of this work to reduce the restrictions that all twelve had to be included and make it able to use any subset of the twelve that are wished, in such a way that with limited experience in computer programming was sufficient to operate the program.

Also more options as to what type of graphs, and initial run conditions were added to make use easier, as well as the addition of confidence intervals for each component concentration.

It is now hoped that with these simplifications and added options that this model can now become a viable tool in the field of water pollution.
