FORTRAN Routine for Implementing the Linear Reservoir

摘要

The Nash model defining parameters n and k, were used to derive the instantaneous unit hydrograph from moment relations of simulated rainfall-runoff data. A simulated storm of intensity 140mm/hr. and duration 140secs. gave model parameters values of 1.74 and 28.50 for n and k respectively. Model validation was carried out using a storm of another characteristics to obtain a runoff event which simulated the observed runoff with an accuracy exceeding 90%. The procedure is described in a tabulated FORTRAN programme.
