Efektivitas Model Konseptual GR4J Dan Ihacres Untuk Analisis Ketersediaan Air Di DAS Kampar (Studi Kasus : Sub Das Kampar Kanan)
The availability of water in the Sub DAS Kampar Kanan which has an important role in addition to being a catch for the Kampar river as well as where the PLTA Koto Panjang hydropower reservoir is located. The hydrological model to be used is the GR4J Model (Genie Rural a 4 parametres Journalier) developed by Perrin, and IHACRES model developed at Australian National University (ANU). The GR4J model is a simple model because that only focuses on four parameters. While the IHACRES model produces parameters a nonlinear loss module and linear unit hidrograf module. The study area includes the Rain recording Pantai Raja station and the Pasar Kampar station of climatology station while the AWLR lake Bingkuang stasion. determine the success of the model in the Kampar watershed (DAS) using the R2 and R are used to calculate the deviations that occur in the observation ndiscarge and simulation discharge. The stages that will be used in data length configuration are calibration, verification and simulation.
The results of the study on the analysis of water availability in Lake Bingkuang showed a better GR4J model. Availability of water for irrigation with a probability 80% the maximum discharge value is 278,2 m3/s while the mainstay discharge is 257 m3/s. Availability of water for power plants with a probability 95% the maximum 280,9 m3/s while the mainstay discharge is a minimum of 223,9 m3/s.
