Data Analysis And Management For Dynamic Model Of Water Distribution System

With the development of information management technology of water supply, water distribution system modeling has become modern technology in design, construction and operational guidance for water distribution system. The modeling method is becoming more and more important. However, limited by the data condition of national water enterprises, it is necessary to define the data requirement of setting up a model, the processing methods of the data collected, and the exploitation of the data. Besides, it is also necessary to build a modeling data management system and improve the perfection of the existing data.In this dissertation, a standard method of data collecting, processing and exploitation in modeling is established for national cities. Data for dynamic model are classified and analyzed. The data quality is assessed with comprehensive fuzzy evaluation method. A collection scheme is given for the dynamic modeling of water distribution. A processing method system of high efficiency is set up, including the data converting method from GIS to model, the interpolation method for node altitude and the least square polynomial fitting for data from SCAD A. All the work above is quite meaningful to the water enterprises, because it can help them have a clear understanding and make best use of their data. Furthermore, in order to standardize the management of the data, an integrated data management system is set up base of the database system. The data management system has a clear data structure and appropriate managing way, which will help in data management work of water enterprises.In the end, a case of dynamic modeling is given to describe the analysis and management of the data during the modeling process. In this case we can find that water distribution data guarantees the effectiveness of the hydraulic model, and theapplication of model can also accelerate the development and perfection of data.
