- Abstract:
- Based on analysis of the operation and management requirements of Kunming drainage network, long-term fixed and temporary measuring points were selected to construct an online liquid level monitoring system. Liquid level data analysis and application mode were discussed from four aspects (warning and forecasting of water level, variations in liquid level in dry weather, response of liquid level in wet weather and relationship of upstream and downstream level),so as to guide the operation and maintenance of facilities, divide the risk level of different area, identify the law of water level change, trace the source of abnormal drainage events,assess the overflow risk in wet weather and analyze the correlation of liquid levels in upstream and downstream connected pipelines. The liquid level monitoring data can be employed to guide the operation and management of drainage facilities, improve emergency response capability of urban drainage, which provides experience for other cities to build liquid level monitoring network and realize intelligent management of drainage facilities.
