Abstract

Dynamic management of urban drainage networks necessitates the integration of cyber-physical systems to overcome the limitations of static design approaches. This study presents a universal technical handbook that combines the topological integrity of AutoCAD Civil 3D with the full dynamic modeling capacity of the SewerGEMS platform. The methodology systematizes topological data integration in a step-by-step manner, incorporating the numerical configuration where Saint-Venant equations are solved via a four-point implicit finite difference scheme and the Newton-Raphson iteration method. The study defines the integration protocol of Extended Period Simulation (EPS) and SCADA-based continuous multipliers, necessary for the system to evolve into a living digital twin (living DT) form, as a technical procedure. The sensitivity of the Kutter formulation in detecting sedimentation risks, which resolves the non-linear interaction between roughness and energy gradient especially in low-slope lines, is emphasized. In the hydrodynamic control phase, occupancy rates exceeding the 70-80% threshold and flow velocities falling below 0.50-0.60 m/s are identified as primary operational risk indicators regarding corrosion, gas accumulation, and capacity loss. This guide establishes a proactive decision support mechanism that prioritizes rehabilitation strategies, such as cured-in-place pipe (CIPP) and egg-shaped pipe optimization, through what-if scenarios. This integrated approach offers a resilient and universal engineering standard for sustainable urban infrastructure management.

Özet

Kentsel drenaj şebekelerinin dinamik yönetimi, statik tasarım yaklaşımlarının kısıtlarını aşmak adına siber-fiziksel sistemlerin entegrasyonunu gerektirmektedir. Bu çalışma, AutoCAD Civil 3D’nin topolojik bütünlüğü ile SewerGEMS platformunun tam dinamik modelleme kapasitesini birleştiren evrensel bir teknik kılavuz sunmaktadır. Metodoloji; topolojik veri entegrasyonu, Saint-Venant denklemlerinin dört-nokta örtük sonlu farklar şeması ve Newton-Raphson iterasyon yöntemiyle çözüldüğü sayısal konfigürasyonu adım adım sistematize etmektedir. Çalışma, sistemin yaşayan bir dijital ikiz formuna evrilmesi için gerekli olan Genişletilmiş Zaman Simülasyonu (EPS) ve SCADA tabanlı sürekli çarpanların entegrasyon protokolünü teknik bir prosedür olarak tanımlamaktadır. Özellikle düşük eğimli hatlarda pürüzlülük ve enerji eğimi arasındaki lineer olmayan etkileşimi çözen Kutter formülasyonunun, sedimantasyon risklerini saptamadaki hassasiyeti vurgulanmıştır. Hidrodinamik denetim aşamasında, doluluk oranlarının %70-80 eşiğini aşması ve akış hızlarının 0,50-0,60 m/s altına düşmesi; korozyon, gaz birikimi ve kapasite kaybı açısından temel operasyonel risk göstergeleri olarak belirlenmiştir. Sunulan bu rehber, yerinde kaplama (CIPP) ve yumurta kesitli boru optimizasyonu gibi rehabilitasyon stratejilerini olası senaryolarla önceliklendiren proaktif bir karar destek mekanizması tesis etmektedir. Bu bütünleşik yaklaşım, sürdürülebilir kentsel altyapı yönetimi için dirençli ve evrensel bir mühendislik standardı sunmaktadır.
