Step Release into a Stream
In this section of Fate you can enter data to predict the concentration of a pollutant in a stream. The input of the pollutant is treated as a step input; for example, the continuous release of industrial waste and mixing with river water. The model used here is a one-dimensional advection-dispersion equation that can also account for the first-order degradation or removal. A sample problem has been loaded with values similar to those you might need.
