英文摘要 | A general mathematical model for the transfer function of a watershed system developed by Chow and Kulandaiswamy was slightly modified and the application of the proposed model to the Tsengwen reservoir watershed was illustrated. The system storage is shown to be a linear combination of input and output and their derivatives with respect to time. The coefficients are considered to be constant for a given storm and assumed to be functions of certain characteristic values of input. The transfer function of a watershed system, derived from the system storage and the continuity equation, is solved linearly for a particular storm. The watershed system storage is then considered as nonlinear due to the characteristic values of input changing from storm to storm. Thus the model recommended in this study for practical application is quasi-linear. Hydrologic data from six storms on the Tesngwen reservoir watershed were analyzed. The agreement between the observed runoff and the computed runoff from the modified model is shown to be very good. |
