The Weybo river catchment is located in the southern part of Ethiopia. It is confined byrnthe major Omo-Gibe Basin and situated at the south-west margin of the Main EthiopianrnRift.rnThe area is dominantly covered by acid volcanics, both pyroclastic flows and falls, ofrnMiocene to Pliocene age.rnIntegrated approaches are adopted to effect the assessments of water resourcesrnpotential of the catchment. The different components, controls and/or parameters inrneach of the methods are estimated, computed or qualitatively described applyingrndifferent empirical and physical techniques. The different techniques greatly helprncompare resultant values of some parameters, controls or components. It is thisrncomparison that help generate ideas on the power of workability of that specificrntechnique in the study area.rnThis new work reveals an overall balance among the components of the water budget.rnSoil moisture deficits are recorded in months of November through mid March and thernremaining 7 months remain in surplus. However, it has been investigated that the groundrnwater recharge is declining in an appreciable rate for a small decrease in precipitationrnand a moderate increase in surface runoff. The remaining hydrometeorologicalrnparameters show a lower to moderate increase for the last 15-20 years.rnGround water potential of the Weybo River catchment is seen to be under the control ofrnfracturing intensity and degree of weathering. Higher hydraulic conductivity zones arernmapped at or near fractured regions and their values are decreasing away from thernstructures. It has also been seen that aquifers that are formed from the deeplyrnweathered ignimbrites, rhyolites and trachytes yield low and possess a lower hydraulicrnconductivity generally in the order of 0.1-0.5.rnThe apparent resistivity values do not show a clear contrast between the highlyrnweathered aquifer formations and the fractured ones. Lower and nearly similar valuesrn(1-10Î©-m) are obtained in both regions.rnBoth graphical and statistical presentations of the physical and chemical parameters ofrnthe water samples provide a good deal of information on the characteristics of groundrnwater flow systems, recharging and discharging zones, and aquifer interconnectivity inrneast and north-east parts of the study area and its neighboring watershed. Piper, Collins,rnSchoeller, HCA and 2-dimentional surfer plots have been used to facilitate analyses andrninterpretations of the data.rnChloride-mass-balance technique results an over-estimated rate of recharge in the studyrnarea, which is calculated to be 123.5mm/annum. The most likely justifications are cited,rnand suggestions are also forwarded in a view to bring the method in to effect
