Enhancement and Application of Minnesota Dry Swale Calculator

Swales and/or drainage ditches for linear road projects have excellent potential for stormwater treatment. They can infiltrate water into the soil, filter sediments and associated pollutants out of the water, and settle solids onto the soil surface. Infiltration rate is a controlling factor for the water quality performance of swales. The objectives of this project are to develop a dry swale calculator that will use soil data to provide time-varying infiltration rate and provide case studies on how to implement the enhanced calculation technique for comparison to the dry swale calculator. The result will be a computer program that will determine the pollution prevention of swales with minimal input data.
