dc.description.abstract | Linear transfer-function models Here fitted to different
sets of concurrent daily areal rainfall and runof'f series. The
daily rainfall and runoff records used were for two different
catchments namely the Yala and Sondu river basins. Two wet;
seasons extending from April to June and August to October
over the years 1972 to 1978,were considered in fitting the
models,
Prior to fitting the models, the areal rainfall and
runoff t.Linear series were subjected to several time and frequency
domain analyses, In the time domain the auto correlation,
partial-auto correlation and cross-correlation functions were
estimated, whiIe in the frequency domain the spectral. and crosss pectral
functions were computed. The characteristics of these
functions were used t,o identify the orders of the rainfall runoff
models for each of the two seasons within the seven years. | en |
