Abstract

This research intends to investigate the land cover change and to obtain the canopy
interception in the Lesti sub-watershed, and to produce the rainfall-discharge modeling as the function of the
net rainfall factor. The Lesti sub-watershed is selected because it has the basic physical condition and the
Automatic Water Level Recorder (AWLR) data for carrying out the calibration. The methodology consists of
identifying the land cover based on the Normalized Difference Vegetation Index (NDVI) classification,
carrying out the field study to obtain the canopy interception, using the net-rainfall modeling as the input on
the rainfall-discharge modeling of F.J. Mock. The net rainfall modeling which is designed in this research is
as the correlation between the rainfall which is dropped and the canopy interception. The result shows that
the use of net-rainfall on the rainfall-discharge modeling of F.J. Mock can increase the accuracy of generated
discharge which is strongly influenced by the proportional of land classification
