Optimum management of water and wastewater network in GIS environment using geospatial database, a case study on part of Ahvaz city, SW Iran

Abstract

Nowadays, establishing a geospatial database is commonly the first step for managing the urban services. The aim of this paper is designing and implementing a cost-effective kind of geospatial database for managing water and wastewater networks. At first, it was essential to detect and remove different kinds of possible errors like; spatial, temporal and etc. Then, complete conceptual diagram is drawn for modeling and implementing geometric network in spatial database. After that, the geometric network designed for modeling flow is weighted based on transferring water volume, scale of pressure and the pump strength. Furthermore, customer\\\\\\\\\\\\\\'s demand is considered as a driven defined weight, for GIS analysis function. The wastewaters, in the geometric network are weighted using pipe\\\\\\\\\\\\\\'s diameters because of ground gradient. Finally, spatial networks functions are implemented together for optimum managing network. The final results demonstrate high ability of geospatial database for managing water and wastewater networks.
