Flow-routing at a tributary (Koros River) of the Tisza River in Hungary was achieved by relating the storage coefficient (k )o f the state-space formulated discrete linear cascade model (DLCM) to the concurrent discharge rate of the Tisza. As ar esult, the root mean square error of the 1-day forecasts decreased from 25 m 3 ·s −1 (k ¼ 1.7 days −1 and the number of storage elements is 2) with the corresponding Nash-Sutcliffe-type performance value of 0.95 to 11 m 3 ·s −1 in the calibration period… Expand
