Abstract

This paper presents a computer algorithm for derivation of design rainfall temporal patterns which are widely used in rainfall runoff modeling. The algorithm identifies design storms of durations of 10 minutes to 120 hours from continuous rainfall data and then applies Method of Average Variability to produce design rainfall temporal patterns following the procedures recommended in Australian Rainfall and Runoff – the national guide for design streamflow estimation in Australia. The algorithm has been tested using rainfall data from the Gold Coast region in Australia and has been found to produce satisfactory results. The algorithm would be useful in deriving design rainfall temporal patterns where such data are unavailable and to update existing design rainfall temporal patterns data in a region to capture recent trends in rainfall characteristics.

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
