ANALISIS KELAYAKAN MODEL NAM (NEDBOR AFSTROMNINGS MODEL) UNTUK PREDIKSI KETERSEDIAAN AIR PADA DAS HO

Abstract

This sudy was conducted at Ho Watershed which is located in Tabanan,Bali. The optimal parameter of the NAM model were CQOF = 0.27, Umax = 70,CLOF = 0.71, CLG = 0.45, CQIF = 0.001, CKBFU = 0.04, CLIF = 0.01, CKBFL =15, CK1 = 0.75, CBFL = 0.25, CK2= 0.50, L/Lmax = 0.8, and the initial value wereQIF2 + QOF2 = 3, U = 50, BFL = 0.001, BFU = 3.75, SM = 100.Verification of the model indicated that the NAM model was statisticallysuitable to be applied at Ho Watershed for prediction of water availability.
