Following the summer recession, the deepest piezometer (WL1-80) showed a cyclic annual variation, with the water table rising in early May in response to rainfall recharge (as seen from the hyetograph in Fig.
The hyetograph and single peak storm hydrograph analysis demonstrate the quick responses of these two catchments with the stormflow (QF) duration and time of concentration ([t.sub.c]) were faster in C3 than in C1, while the times to peak ([t.sub.p]) were almost the same for both (Table 3).
In this respect four storm which have symmetric hydrograph and hyetograph were chosen and the basin flood hydrographs were simulated with the HEC-HMS model by using the SCS empirical method and the Curve number, lag time and the loss rate were also calibrated.
* rainfall intensity distributed across 4 time periods; a design hyetograph from Pilgrim (1987) was used to estimate time variation in rainfall intensity, with the resulting hyetographs shown in Fig.
(4) Route the rainfall excess hyetograph, for each duration, through the catchment model to generate the flood hydrograph.
The rainfall hyetograph is illustrated in Figure 14.
Direct run-off hydrograph {Q(t)} at the test-watershed outlet, determined as convolution integral of watershed-specific excess rainfall hyetograph {[I.sub.e](t)} and hydrologic response function U(t), can be expressed hence finally as:
