Developing river rehabilitation scenarios by integrating landscape and hydrodynamic modeling for the Ciliwung River in Jakarta, Indonesia

摘要: Abstract Landscape visualization and modeling has progressively merged over the last decade providing ever increasing accuracy realism. As powerful as visualized landscapes may be, there is a need to integrate them with numerical models simulate real world dynamics, by doing so, move beyond purely visual evocative expression one which physically grounded in reality. In this paper, we present an approach that integrates landscape hydrodynamic through modification testing of point cloud data assess flooding Ciliwung River Jakarta, Indonesia. We propose series 6 scenarios along 40 km course river corridor ranging from governments’ “normalisation” proposal green infrastructure scenario our team. Through such flood simulations have found severity floods can only be contained implementing extensive normalized canal planned, however, scale intervention at hand possible impacts further downstream carefully weighed in. Likewise, while seen alternative management, it unlikely mitigate effects most severe floods. reality, careful combination two extreme new concrete channel will likely provide best balance between mitigation riparian restoration. The integrated presented here provides platform refine into caters all stakeholders Bogor, Depok Jakarta regions.
