Short summary
This paper explores the reliability of low-flow simulations by conceptual models in a semi-arid, Andean catchment facing climate variability and water-use changes. A parsimonious hydrological model (GR4J) was combined with a model of irrigation water-use (IWU) to provide a new model of the catchment behavior (called GR4J/IWU). The original GR4J model and the GR6J model were also used as benchmarks to evaluate the usefulness explicitly accounting for water abstractions.
