Abstract:
This study highlights the critical importance of accurate and comprehensive physical data in Integrated Urban Water Management (IUWM) and sustainable planning of water resources. Inaccurate or insufficient physical data can directly impact the reliability and sensitivity of planning, making it crucial for administrations to maintain accurate, thorough, and up-to-date data. To achieve reliable simulation results from hydrodynamic models, it is essential to define actual conditions in the model using correct and complete physical datasets. The study proposes a methodology for handling physical datasets of infrastructure systems in a GIS environment to obtain reliable simulation results. Digital and non-digital data from existing infrastructure systems are obtained and transferred to the GIS environment, with subroutines applied as needed to ensure accuracy and completeness. The physical data is then combined into a single database, correcting deficiencies and ensuring upstream-downstream continuity in the hydraulic model structure. With the integration of all physical data into the GIS environment, analysis and queries of geometric and attribute information are carried out for the detection and correction of deficiencies and errors of the system elements. This approach resulted in high-precision planning, detecting and correcting deficiencies and errors of the system elements, and ensuring the upstream-downstream continuity relationship in the hydraulic model structure. This study emphasizes the significance of accurate physical data in the sustainable management of urban infrastructure systems, and the proposed method can be utilized for any level of planning. Accurate and up-to-date physical data is essential for the sustainable management of urban infrastructure systems, and the use of the GIS environment and hydrodynamic models can lead to high-precision planning and reliable simulation results.
