Simulasi Dinamika Aliran Sungai Ciliwung Hulu Berdasarkan Prinsip Active-Walker

Abstract

Active Walker ( AW ) is agent based modeling where walker as an agent change its environment when it runs , and the next step is influenced by the changing environment. In this study, modeled the dynamics of the Ciliwung River upstream based on active walker principle. This model use DEM SRTM data that has a spatial resolution of 90 m x 90 m and 15 m x 15 m. The data were processed using ArcGIS 9.3 software to view elevation data points of each river. The elevation data are used as landscape in Ciliwung river upstream model based on active walker principle. This model also uses a data of flow, width and depth of the river were obtained from field survey. From this research, we concluded that river of Gunung Mas has influence on the end speed of Katulampa’s dam than river of Katulampa. This simulation has similar characteristics of river flow with state of Upper Ciliwung so the AW principle can be used for modeling the Ciliwung river upstream .
