KALIBRASI MODEL IHACRES PADA DUA DAS IDENTIK
Abstract
IHACRES has been applied on two sub-catchments (Kloposawit and Rawatmatu). These two sub-catchment are
geographically located at the same climatic regions and having physical characteristic that relatively similair. A series of
calibration and validation procedures have been conducted on these two similar sub-catchment to show how the the
model response to the “parameter setting” that reltifely identic. Firstly, the model is calibrated on each sub-catchment
independently. A validation process on each sub-catchment is also conducted using different time-series bound. These
processes produce a set of “optimal parameter value” for each sub-catchment. Furthermore, optimal setting of
parameter values of the first sub-cathments is validated on the second and vice versa. Finally, two seting of parameter
value are compared. The result show that calibration and validation of IHACRES on both sub-catchment are successfully
conducted by means of setting parameter value that relatively identic.
