N2 - The physically based Institute of Hydrology Distributed Model is briefly described and its sensitivity to the parameters of the surface and subsurface flow components is examined for the Tanllwyth catchment, Powys, Wales. Model predictions are most sensitive to a surface flow roughness parameter and the saturated hydraulic conductivity of the soil. Uncertainty in the effective values of these parameters is assessed by comparing observed and predicted discharges for a number of storms. The effect of uncertainty in the effective parameter values on the predicted discharges for two additional storms is assessed using the Rosenblueth method.
