Abstract

Abstract
To achieve sustainable development, well understanding of urban water supply systems is crucial which water distribution network (WDN) is one of the important structures in urban water supply systems. The WDN plays a vital role in preserving and providing a satisfying life quality, which the flow direction of pipelines is one of the major components. Traditionally, the flow direction of WDN in urban areas has been determined based on the technician's memory and experience. Nowadays, the traditional method cannot give a reliable analysis based on the complexities in the network. The light detection and ranging (LiDAR) is a comparatively quick technique for extracting precise and accurate surface models and therefore, offers the potential for creating DEMs, 3D surface models, and other mapping products such as flow direction with decimeter accuracy. The present study aimed to investigate the potential use of LiDAR data for creating a digital elevation model and subsequently a 3D surface model to determine the flow direction of the water pipeline network. Taman Mutiara Rini, Johor Bahru, Johor, Malaysia (with a population of around 3 million) as a flat area was selected to estimate the flow direction of WDN. Also, GIS-based LiDAR data was employed to determine the flow direction of WDN. LiDAR data had a great potential to determine the flow direction of the WDN, which illustrated about 77% agreement with the real data. Our results suggested that LiDAR could be a useful technology to determine the flow direction of WDN in the flat urban area.
