Abstract：Mountain flood disasters have features of unpredictable and catastrophic,with difficulties for early warning and complexity in hazard mechanism,resulting challenges for early warning.To address the limitations of traditional warning systems,such as low accuracy,limited coverage and inadequate process management,we developed a multi-stage progressive mountain flood monitoring and early warning system based on LBS(Location-Based Service)positioning technology.The system adopts a B/S architecture to create a four-layer collaborative framework(data-service-business-application).Data of precipitation and hydrological monitoring and meteorological forecasts are integrated to create a three-stage progressive warning mechanism of"meteorological pre-warning,short-term dynamic warning and real-time targeted warning".Moreover,the system employs dynamic target warning technology and LBS positioning and cellular data analysis,to achieve complete and precise coverage of warning objects in small watersheds.The problems with traditional models are overcomed.Since the operation of the system,it has played an active role in disaster monitoring and warning dissemination.In particularly during the heavy rainfall triggered by Typhoon Doksuri,the system provided timely and accurate targeted warnings to the affected areas for evacuation.
