Abstract
Rising population, increasing water demand for irrigation development, domestic water demand, livestock, and lack of efficient water use awareness are of major concern in Ruvubu catchment. Also the implementation of environmental flows and the need to meet international flow requirement are going to greatly exacerbate the complexity of the future water resources management in what is already a water stressed catchment. This study aimed to focus on determination of the best water allocation option in the Ruvubu catchment. Therefore on water supply data (stream flow on 11 gauging stations; rainfall data) and water demand (water required and /or used by each sector data at any demand site) were collected from the catchment for the period of 1982- 2007. The WEAP model was used as an environment of simulating water demand scenario management according to its powerful scenario analysis capacities. The model was configured by locating the main water resources and water demand found in the catchment. Six scenarios such as reference, high agriculture population growth, environmental flow requirement, efficient irrigation and water demand management were developed and analyzed. The results analysis has shown the efficient irrigation scenario could be the best water allocation option in the Ruvubu catchment in sense it would improve water allocation of 15.6 Mm3 (47%), 23 Mm3 (51%) to Agriculture and Domestic water user sectors respectively from the reference scenario while other scenarios would reduce water supply to those sectors. Other water allocation models should be applied on the same catchment and compared to the WEAP model results.
