Abstract:
The effects of urban vegetation on storm water runoff were documented using a model based on the curve number technique developed by the Soil Conservation Service. The study was conducted in three Parts. The first section analyzes the percentages of land use and land cover types found in a primarily residential watershed located in Tucson, Arizona. The second section evaluated four models for the ability to accurately predict storm water runoff. The final section analyzed the effects of four canopy cover scenarios: 0%, 21% (existing), 35% and 50% on the volume of stormwater runoff. Land cover percentages were found to differ from other cities in three areas: tree canopy, bare soil, and impervious surface. Runoff models that have curve numbers which have been lumped or weighted underestimated runoff while the model which summed the volumes of runoff from each cover type overestimated runoff. Tree canopy cover was found to not have a large impact on urban storm water runoff. Existing canopy cover reduced runoff by 3.8%. By increasing canopy cover from 0% to 50%, annual reductions in runoff of about 8.1% could be expected.
