Abstract: The restriction and water-use plan for periods of water deficit is a key instrument in water-resource management. It defines a set of gradual measures for limiting and prioritizing water consumption when river discharge falls below predetermined critical thresholds. In Romania, the National Administration “Romanian Waters” (ANAR) and its subordinate River Basin Administrations are responsible for developing and implementing such plans. In this study, we employed the NAM lumped-conceptual rainfall–runoff model within the DHI software suite, as it is a suitable tool for estimating water availability in ungauged catchments. The model provided good results in estimating water volume (for about 84% of the sub-basins, the simulated water volume was overestimated or underestimated by up to 10%). However, its performance was unsatisfactory in reproducing the flow hydrograph shape (only 12% of the sub-basins had R² > 0.7). Only a small number of sub-basins met both the R² > 0.7 threshold and the ±10% water balance error criterion.
