Recently, H. C. Riggs has described the basis for design-flood frequency curves which are expansions of ordinary flood frequency curve data. The procedure is simple but time consuming. To speed up the process, two simplified techniques are presented herein: (1) the base-curve method; and (2) the point-offset method.
