In this paper, we investigated the transferability of a distributed hydrological model to better realize flood predictions at ungauged basins with different hydro‐climatic characteristics. First, the transferability of a distributed hydrological model's parameters calibrated at the basin outlet in order to make consistent predictions at ungauged internal sub‐basins for a range of floods with different initial conditions is investigated. It is found that the transferred model parameters can be used to make reasonable predictions at ungauged internal sub‐basins for flood events with wet initial conditions. In contrast, the prediction accuracy at internal sub‐basins is found to be low for floods that have initially dry conditions. By incorporating the spatial heterogeneity of the parameters, depending on the topography, we are better able to predict floods with initially dry conditions.
