The method was originally proposed by De Laine. This technique was tested on floods recorded on a 1.07 square mile watershed in Arizona, on floods simulated on the 1/2 acre Experimental Rainfall-Runoff Facility at Colorado State University and finally on flood simulated on a 40 acre hypothetical watershed. It was found that De Laine's method is practical only on error-free data. If there is any error in the determination of the rainfall excess, or in the measurement of runoff or in the synchronization of rainfall and runoff records, the solution becomes unstable. The method produced unsatisfactory results for the Safford, Arizona and the CSU-ERRF data.reportsengCopyright and other restrictions may apply.
