An improved understanding of water balances of rivers is fundamental in water resource management. Effective use of a water balance approach requires thorough identification of sources of uncertainty around all terms in the analysis and can benefit from additional, independent information that can be used to interpret the accuracy of the residual term of a water balance. We use a Monte Carlo approach to estimate a longitudinal river channel water balance and to identify its sources of uncertainty for a regulated river in south-eastern Australia, assuming that the residual term of this water balance represents fluxes between groundwater and the river. Additional information from short term mo..View full abstract
