Abstract

Water allocation is the process of regulating water provision in a certain amount and time, based on water availability and user needs, according to the type of use and priority order. This requires integrating all water users’ needs according to priorities, considering water availability. Tukad Oos plays a crucial role as a water source, meeting the needs of the surrounding population. The problem that occurs is the lack of integration of water utilisation patterns, especially for irrigation, where the use of water from upstream to downstream does not take into account the amount of water available. Therefore, it is necessary to conduct scientific research by considering the necessary analyses to analyze and evaluate the water balance that occurs in the Tukad Oos watershed. This study provides results that the potential availability of water in the Tukad Oos Watershed is currently 950.33 m³/second/year with a reliability level of 80%. The condition of the water balance in the Tukad Oos Watershed generally shows a surplus value of water with an average total surplus discharge of 10.19 m³/second at the outlet position. The water allocation management strategy in the Tukad Oos Watershed should prioritize fulfilling irrigation water needs by rearranging the existing cropping pattern and area, thereby integrating surface water use to maintain the watershed’s sustainability.
