UM-27 : Graphical representation of flow duration curve

Abstract

Flow duration curve, representating the combined effect of flow characteristics of any stream, is one of the simplest available techniques to predict the distribution of future flows. Because of its frequent use in hydrologic studies, the generalised software package 'FLOW' has specifically been developed to assist the designer for graphical representation of flow duration curve. This user manual provides documentation of the program runnable on an IBM-compatible microcomputer, including features such as:

(i) Equipment and software requirement

(ii) Data requirements and preparation

(iii) Steps for Running the program

(iv) Procedure used computation

(v) Brief description of the sub-routines

(vi) Sample Input and Output Files

Besides a flow chart showing the operation of the program has also been given in the user's manual.
