| dc.description.abstract | Research of effects watershed geomorphology characteristics on peak discharge of runoff and time to peak discharge, and modelling discharge of runoff must be conducted, because watershed management in Indonesia. The objective of this research are: 1) to study effects of geomorphology characteristics on peak discharge of runoff, and 2) to design prediction model of discharge runoff. The result indicate that geomorphology characteristics of watershed (geometric and morphometric) have an effect to peak discharge of runoff and time to peak discharge, when lower total channel-segment length, gravelius index, bifurcation ratio ( Rb), and ratio of mean length (RL) of watershed will have to higher peak discharge of runoff and higher drainage density will have a lower time to peak discharge. Model of discharge runoff by production function and transfer function models have a high accuration level (F>85%) between simulation and measurement result. | id |
