Drainage Network Of The Geographic Information System Design And Implementation

Along the city urban development, and the urban sewerage networks system always built constantly, the management of the urban sewerage networks also need to be improved. Currently, so it is difficult to suffice the modern needing of the municipal management by conventional handcraft management method. Therefore , we need to build up a modern GIS information management system, which can meet with the needs of administration department design department and building department.Currently, the research of the sewerage networks GIS information management system in our country is in the preliminary phase of spatial inquiry, data browse, statistics analysis, simple spatial analysis. Enhancing the function of the sewerage networks GIS information management system and embodying the hydrodynamic model and other sewerage specialty model is the main development trend of the domestic sewerage networks GIS information management system, to enhance the spatial analysis capacity.This thesis uses the Heping village district of Baotou city graphic data and property data as processing object, property database and spatial database are established in the platform of the Arc GIS Desktop produced by ESRI and the design of system interface. We fulfilled the following functions: data collection data import data store data compile in time updating and data output ,the connection of spatial data and property data database management SQL limit condition inquire layer control display statistics summarize analysis and buffer analysis etc.This thesis also discusses primarily how to build the hydrodynamic model surface runoff rainfall dependent inflow & infiltration ,sewage simulation ,the calibration , and also validates the hydrodynamic model on the sewerage networks GIS database.
