Mean peak time error (E T ) averaged over the two sub-periods in calibrationand validation mode at the Tahlequah (downstream end of the reach), SiloamSprings (interior of the reach) and Kansas (tributary) stations with an increasingnumber of tributaries modelled individually. The mean peak time error was calculatedon the 15 events listed in Table 1. The criteria were not calculated at theKansas station for the configuration having only one tributary (see section 4).40
