Application Of The Wavelet Analysis In A University

With the continuous development of the decades of reform and opening-up in guangzhou,Guangzhou has grown into the national GDP ranked third in Chinese cities for many years,and become one of the five national central cities(The only municipality directly under the central city).Part of the drainage pipe network in the central city in Guangzhou was builded early,and the design standard is low,the Pipe diameter is not in conformity with the current standards,there are some low-lying region in the central city in Guangzhou.When the storm comes,poor drainage and there are more waterlogging events.the city urban waterlogging have affected people's normal life,and caused great damage to property.Such drainage system is highly adapted to the requirements of the guangzhou national center city.City urban waterlogging and drainage facilities renovation is becoming the need of he sustainable development in Guangzhou.This paper demonstrates comprehensively the current situation and causes of waterlogging at home and abroad city,and analyzed the Solutions to regional waterlogging at home and abroad city,those Solutions,some of therm are also well used for reference in the waterlogging in a campus area of a university in Guangzhou.In the example of water logging control in the campus area of a university in Guangzhou,this paper analyzes and processes basic data such as the actual regional landform,drainage network distribution,river water level downstream,and input the basic data into the Infoworks Integrated Catchment Management urban integrated catchment drainage model system,the simulation is based on the city's specific storm intensity formula,using the Chicago process line model to synthesize rainfall scenarios with multiple recurrence periods,and the operation under different rainfall conditions is simulated,the campus water drainage network system model was established,It provides a reasonable scientific basis and reference for the dentification of the problems of the drainage network system and the overall evaluation of the system service performance.Identification of the drainage network system under the simulative results,combining the calculation and analysis of Actual basic data,According to the principle of " high water discharge,low water pump ",this paper puts forward corresponding engineering solution measures.After the implementation of the project,through the related department's report data,obtains the direct effect to reflect,and this paper enter the actual data into the Infoworks Integrated Catchment Management urban integrated catchment drainage model system after the completion of the renovation project,the effect of the water logging reconstruction measures is verified by simulation.In this paper,the data of water logging reconstruction in a university campus in Guangzhou is simulated and analyzed,the regulation of waterlogging control in regional municipal pipe network is explored,and combined with the actual operation situation after completion of the project,some optimization suggestions are put forward,it is an object lesson in how to carry out the whole city waterlogging reconstruction in the future,it means very important.
