An investigation of the SCS runoff equation as a means of measuring and reducing runoff in residential development

TL;DRAbstract

This study was undertaken to investigate and discuss the use of the soil conservation service runoff equation as a design guide for residential development design. The objectives of the study were (i) to determine the extent to which a hypothetical residential development scheme affected the site's runoff volume and peak discharge rate, (ii) to use the existing SCS runoff equation to predict hypothetical pre- and post-development runoff volumes and rates, (iii) to apply the above findings to a design revision of the residential site plan in order to produce less runoff modification as a result of the development. The Crapo Estate in Muncie, Indiana was chosen as the site for the study. Site analysis data and an initial design (Scheme A) from a fourth year undergraduate design studio were used with the runoff equation to predict pre- and post-development runoff volumes and rates. Curve number (CH) maps were then constructed by overlaying site land uses and soil types. These maps indicat
