dc.description.abstractThis study focused on water allocation for different purposes in Tiga dam, using WEAP model to carry out analysis of the hydrological and meteorological information of the study area, with a view to settling the conflict between water allocation of Kano City and major irrigation project. The research commenced with a preliminary site investigation through reconnaissance survey to analyzeactivities related to water resources in the basin. Meteorological and hydrological data were also collected and used to model the hydrological process of Tiga Dam. The model was validated and calibrated using simulated net-evaporation and observe net-evaporation. Meteorological and hydrological data, population and their growth rate, irrigation area and number of industries from 1987 to 2017(31 years) were used in WEAP model software. The model predicted that in the future time from 2031 to 2050 the dam might not meet up with the total demand. Itonly capable of supplying annual average of 410.5 Mm3 for agriculture with unmet demand of 123.7 Mm3 and when per hectare demand increase by 33.9%(agricultural scenario), it will supply 658.8 Mm3 with unmet demand of 188 Mm3.It will also supply annual average of 266.3Mm3 for Kano population with unmet demand of 61.6 Mm3and 301.3 Mm3 when per capital demand is increase by 14.3% (Kano population scenario) with 75.3 Mm3 unmet demand. Annual average supply toKano industries were 15.5 Mm3with unmet demand of 5.4 Mm3 and 20.2 Mm3 with 7Mm3 unmet demandwhen industrial allocation is increase by 30.4% (Kano industrial scenario). The Tiga Reservoir will generate 21288.8GJ annual average hydropower with 161.98GJ unmet hydropower demand from 2026. In general, this model predicts that the annual average future water supply from 2018 to 2050 for all purpose is 692.4 Mm3 with unmet demand of 190.8 Mm3 from 2031 but 980.3 Mm3 for all scenarios with unmet demand of 270.5 Mm3.en_US
