# flo\_dist

The distance between the aquifer and the stream impacts the delivery of pesticides from the aquifer to the stream. The longer the distance, the smaller the pesticide load. 

This variable is only used for calculating pesticide transport from the aquifer to the stream, not for flow or nutrient routing.
