Abstract. In this note, we present RAT, a new method to assess the robustness of hydrological models. RAT can be seen as an alternative classical split-sample test widely used in hydrology. And because does not require multiple calibrations, suggest that it applied even uncalibrated The determine whether model is "safe" for being climate change impact studies.
