Abstract: This study presents a cost-effective workflow combining consumer-grade mobile LiDAR (iPhone) with 2D hydraulic modeling (HEC-RAS) for urban stormwater assessment. Applied to a university campus, the method successfully identified critical drainage zones, flow pathways, and areas of water accumulation during storm events. Results demonstrate that accessible mobile sensing technology can provide engineering-grade hydraulic analysis without expensive equipment or specialized expertise, significantly lowering barriers to stormwater modeling. This framework enables rapid assessment of urban runoff characteristics and establishes a foundation for evaluating Low Impact Development (LID) strategies in different urban settings.
