KALIBRASI MODEL IHACRES PADA DUA DAS IDENTIK
MetadataShow full item record
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.
