| Abstract: | Water resources management under socio-economic and future climate change is very crucial, particularly while striving to achieve the Sustainable Development Goals (SDGs) related to water. A water Evaluation and Planning System (WEAP) model was used to explore the quantity of surface water, demand, allocate the resources and apply different integration measures to meet unmet demand in the Great Ruaha River Catchment. The WEAP model was calibrated using river gauge stations, 1KA31. For 1KA31 (2006-2010) calibration, NSE, R2, and RSR was 0.88, 0.88 and 0.35, respectively and validation (2011-2015), NSE, R2, and RSR was 0.83, 0.87 and 0.42, respectively. Three scenarios were developed and evaluated. First was the reference scenario, evaluated the situation as it is without imposing any changes. The results show that in the current account (2010) average annual runoff was 109.88 m3/s, the minimum runoff was 37.77 m3/s, and the maximum was 262.93 m3/s. In future, (2050) result shows that average annual runoff will be 126.78 m3/s, minimum runoff 47 m3/s and maximum 308.06 m3/s, whereas, demand 2010 was 100% covered (980.52 Mm3) and in future demand of 168.14 Mm3 (2030), 381.45 Mm3 (2040) and 844.26 Mm3 (2050) will not be met, which is 13% of uncovered percent. The second was the demand management scenario, assessed reuse of the supply (40%) and adaptation of modern irrigation methods (50% of all users) to meet unmet demand. The results show that 87% of unmet demand in the second scenario will be covered. Third, storage reservoirs scenario, three reservoirs evaluated to store water to supplement unmet demand in the second scenario. The results show that the remaining unmet demand 13% from the third scenario will be covered. Therefore, the study recommends the measures in the second and third scenarios should be implemented to meet the demand driven by the high growth of socio-economic and climate change impacts. |
