| Abstract | The WATBAL model is a semi-distributed rainfall-runoff
model and represent an intermediate approach as compared with
the two-alternative rainfall-runoff model, i.e. lumped and
fully distributed model. The main purpose of the WATBAL model
is to predict the continuous stream flow for an ungauged
watershed.
The WATBAL model was applied in two catchments in Central
Java, Indonesia. One as a "reference" gauged watershed and the
other as "ungauged" test watershed. For the purpose of
predicting the continuous runoff at ungauged watershed,
initially the model was applied at the gauged watershed. After
that, the model was tested to ungauged watershed without
calibration by transferring calibrated parameters value of a
gauged watershed after being adjusted according to the
characteristics of ungauged watershed. The calibration process
was also done in the ungauged catchment in order to know the
uncertainty of the model parameters. Sensitivity analysis of
some parameters were carried out to investigate the effect of
these parameters on the model simulation and to increase the
efficiency of the calibration process.
Comparing between simulated and observed runoff show
that the model can predict a continuous runoff for gauged and
ungauged watershed with satisfactory result, especially
monthly and annual flow. |
