Pemodelan Parameter a Pada Hidrograf Satuan Sintetik Nakayasu (Studi Banding Dengan Hidrograf Satuan Sintetik Gama 1)

Abstract

Choosen of hydrograph parameter  (α)  on hydrograph synthetic of Nakayasu is
subjective depends on raising and recession of the hydrograph’s arc and often got problem
on choosen hydrograph parameter (α).
The research aims are to determine equation of α (alpha) on hydrograph synthetic
of Nakayasu method, and also to analyse effect of river characteristics on α based on
volume control.
Results show that long of watershed and area of watershed were influenced
equation of α..Calculation produce
