A Review on Hydrological Modelling Concepts, Part2: Uncertainty Assessment Concept

Nowadays, uncertainty assessment is a major step in hydrological modelling due to different sources of errors and lack of sureness. Quantifying the amount of uncertainty at models’ outputs is considered as the main step before using the models for water resources decision makings. In modelling processes, the uncertainty quantification is assessed along with model calibration. Therefore, paying attention to the model calibration and its relation with uncertainty assessment is essential. This review paper presents the necessary concepts of uncertainty assessment and their relationship with modelling processes.
