Using a digital computer to estimate the effects of urban development on flood peaks

Using a digital computer to estimate the effects of urban development on flood peaks The digital computer program based on water balance methods and known as the Stanford Watershed Model was used to develop a long‐term continuous hydrograph (1905–1963) for Morrison Creek, Sacramento County, California. By varying constants describing the physical conditions within the watershed according to the amount of urban development and channel improvement within the tributary area, a number of continuous hydrographs were developed. A set of curves was developed from these hydrographs that made possible an estimate of flood peak by frequency for any combination of percentage of area urbanized, percentage of channels improved, and tributary area. An analysis was also made of the effects of urban development on runoff volumes and on the distribution of runoff during the year. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Water Resources Research Wiley

Abstract

The digital computer program based on water balance methods and known as the Stanford Watershed Model was used to develop a long‐term continuous hydrograph (1905–1963) for Morrison Creek, Sacramento County, California. By varying constants describing the physical conditions within the watershed according to the amount of urban development and channel improvement within the tributary area, a number of continuous hydrographs were developed. A set of curves was developed from these hydrographs that made possible an estimate of flood peak by frequency for any combination of percentage of area urbanized, percentage of channels improved, and tributary area. An analysis was also made of the effects of urban development on runoff volumes and on the distribution of runoff during the year.
