The objective of this project is to assess the predictive accuracy of flood frequency estimation for the Rational Method, the NRCS curve number approach, and the Iowa Runoff Chart, for applications to small Iowa streams (drainage areas of 200 acres or less). The evaluation is based on comparisons of flood frequency estimates at sites with sufficiently long streamgage records in the Midwest, and selected urban sites throughout the United States. The sensitivity of estimates to several watershed characteristics, such as soil properties, slope, and land use classification, is also explored.
