Two multiple regression models are used to relate antecedent rainfall to dry seasons flow of 14 rivers serving diversion irrigation systems in the Philippines. The first model expresses streamflow as a function of the bimonthly rainfall totals in centimeters from the preceding 8 months, and the second model relies on the two bimonthly totals most highly correlated to flow and the number of rainy days with 25 mm or more rainfall from the preceding 6 month period. The models have little difference in their predictive accuracy. Although the standard error estimate is relatively high, equations for half of the rivers studied could explain more than 60 percent of the variation in streamflow, and for some rivers over 80 percent in the second model.

Assessment of water yield in a basin is basic to the design and operation of an irrigation project. Very often the streamflow data series are not available for making such an assessment. Under such circumstances stream flow records can be generated by transforming the rainfall records, which are usually available into runoff using some appropriate models. The models employed for such purpose vary from empirical models to conceptual water balance models. A comparison between the performance of an empirical model and a water balance model is attempted in the present paper.
