(Extract From introduction)This volume contains hydrographs of estimated daily flows (discharges) at selected gauging stations on the Jubba and Shebelli rivers for varying periods between 1951 and 1989. It is intended to be a companion volume to the Hydrometric Data Book', but for completeness and ease of reference much of the Introduction to the Data Book is repeated here. All original data has been checked, with errors corrected and missing values in filled where possible. Figure 1 shows the locations of the gauging stations and Table 1 summarizes their main hydrological characteristics
