<p>One of the routines that I am interested in exploring further is the option of including a riparian zone within the Agricultural Catchments Research Unit (ACRU4) model. Once I add the riparian zone to the model, there are a few options available that need to be populated. While most are self explanatory, I am unsure about how the percent riparian infestation option actually works.</p>
