| Abstract |
The base width of instantaneous unit hydrograph -- the time of base for thrity-five watersheds in South Dakota is investigated. This time parameter is correlated with the measurable physical properties of watersheds. A formula equation was derived which correlates the peak runoff and the duration of rainfall excess for a variable rainfall excess pattern. This formula augments theoretical developments in applying the ideas of unit hydrography theory and time of base to analyze runoff data. Based upon this correlation, a new method is developed to determine the flood discharge for ungaged watersheds with area less than 500 sq. miles in South Dakota. (Author) |
