EFFECTIVE RAINFALL ESTIMATION METHODS

This paper presents an assessment of the predictive accuracy of two empirical effective rainfall estimation methods. These methods include the USDA Soil Conservation Service (USDA-SCS) method and the Hershfield method. A soil water balance model (SWBM) was used in the performance of the assessment. Estimates of mean annual monthly effective rainfall by the USDA-SCS and estimates of mean annual growing season effective rainfall by the Hershfield method were found to compare closely with estimates from the SWBM for the well-drained soil but not for the poorly drained soil. Effective rainfall estimates by both methods for either soil condition did not compare well with the SWBM estimates for annual events with return periods higher than the mean annual event.
