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.
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.
This verification agrees with the observation of Zahed Filho and Marcellini (1995) that, even though many papers present a great variability in the time distribution of rainfall events with the same duration, rainfall events of a short duration, less than half an hour, exhibit a hyetograph that is characterized by high intensity at the beginning of the precipitation event (type I).
Potential for landsliding: dependence on hyetograph characteristics.
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.
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.
