In the light of the waterlogging forming reasons in the built area and combined with the areal drainage conditions, the planning is considered to adopt the principle of high water level and high-speed drainage, low water level and low-speed drainage, and waterlogging water pumping and drainage for prevention.

Optimization of planning for drainage system in plain polder area based on experimental genetic algorithm;

A Study on the drainage index for combined control of surface and subsurface waterlogging;

Application of ANN method to real-time operation of drainage system in plain polder region;

The drainage systems of urbanized area include the municipal drainage systems that consist of rain pipes and the hydrological drainage system that developed from the farm drainage system.

It is more required to solve the drainage and flood control problems in time to ensure the people s living and working in peace and contentment.
