| dc.description.abstract | The groundwater potential assessment of Teji river catchment is important to the currently increasing demand of water resources for different developmental activities and its quantification is vital for the efficient and sustainable groundwater resource management. The most important parameter contributing to recharge in the area are rainfall, evapotranspiration rate, and soil types. The area has an annual rainfall of 1104mm. Quantification of potential and actual evapotranspiration of the area is made using different techniques. The results obtained from are compared and representative one is determined to the area and qualitatively described. Water balance studies of the catchment indicate that 325.39mm of water is recharged annually and the months October, November, December, January, February, March, April, and May have soil moisture deficit and the remaining months are soil moisture surplus. The main aquifer identified in the catchment is alluvial sediment, weathered and fractured ignimbrite, and weathered and fractured basalt. Graphical presentation using Piper, Shoeller, Stiff and Wilcox diagram have been used for the effective analyses and interpretation of data. The groundwater in the catchment is characterized by Ca-Mg-Hco3, Ca-Na-Hco3, Ca-Hco3 and Na-Hco3-cl type water. TDS, EC and PH values range 184mg/l-566mg/l, 354μs/cm-838μs/cm and 6.6-7.68 respectively. The water sample analyses made in the catchment indicate the water is suitable for domestic and agricultural purpose. Almost all the water samples analyzed are with in the limits of WHO water quality standards except bore holes drilled at Urogotade PA’s (fluoride = 1.68mg/l) and Asgori town (fluoride = 2.01mg/l & iron=0.39mg/l). | en_US |
