Larry Theller, Kean Jye Tan · Purdue e-Pubs (Purdue University System) · 2015
The STEPL model is a web-based spreadsheet tool designed for the estimation / of pollutant load and to analyze how creation or practicing certain sustainable / activities will reduce pollution in a watershed. For example, leaving a strip of / grass between a farm field and a water feature like stream of lake, will have an / estimated impact on the amount of soil and fertilizer which runs off in to the / river. / The model uses soil properties database, precipitation database and other / factors to make an estimate of pollution reduction after an action. It can then / calculate the cost of applying the action.
