Application of A Tank Model to Assess the Performance of Rotiklot Reservoir Initial Filling
Rotiklot dam is located in Belu Regency that has the tropic climate, with very short wet season (4-5 months) and a very long dry season (7-8 months). The average monthly rainfall in December – April of approximately 300 – 500 mm/month, while in another month only ranges 30- 60 mm/month. During the r...
