Abstract

Flow-duration curves are often used as the basis for grasping the hydrological regime. The flow duration curves by ordinary procedure are usually quite hard to distinguish the difference of one curve from others especially at their high and low flow days. In this study, the new graphical procedure for the flow-duration curves is proposed, in which high and low flow days are both enlarged in a logarithmic way to easily differentiate several flow-duration curves. This is termed “ascending and descending order logarithmic flow-duration curve” from its simple procedure. The process of reaching this idea is described and the characteristics and usefulness of these flow-duration curves are investigated by comparing with the ordinary ones using the Chikugo river discharge data as an example.
