description Disclosed in the present invention is an indirect liquid level monitoring and analysis method for an urban drainage system based on a directed topological network. The method comprises the following steps: constructing a drainage pipe network directed topological model and a drainage pipe network database; extracting the serial numbers of upstream and downstream manholes and pipelines corresponding to monitoring points; preliminarily estimating a liquid level; dividing a pipe network into an upstream area, an upper and middle area and a downstream area; calculating a new liquid level for each node and pipeline in the upper and middle area and the downstream area of the monitoring points; and adjusting the place where a liquid level difference at two ends of a pipeline is too great. In view of monitored values acquired by actual monitoring devices, the urban drainage system based on a directed topological network in the present invention indirectly monitors liquid levels of other pipe networks by means of perf
