Modeling and Design Optimization of Looped Water Distribution Networks using MS Excel: Developing the Open-Source X-WHAT Model
Marcus Nóbrega Gomes, Igor Matheus Benites, Salma M. Elsherif +2
Cost-effective water distribution network (WDN) design with acceptable pressure performance is crucial for the management of drinking water in cities. This paper presents a Microso…
Real-time Regulation of Detention Ponds via Feedback Control: Balancing Flood Mitigation and Water Quality
Marcus Nóbrega Gomes, Ahmad F. Taha, Luis Miguel C. Rápallo +2
Detention ponds can mitigate flooding and improve water quality by allowing the settlement of pollutants. Typically, they are operated with fully open orifices and weirs (i.e., pas…
Control-Theoretic Modeling of Multi-Species Water Quality Dynamics in Drinking Water Networks: Survey, Methods, and Test Cases
Salma M. Elsherif, Shen Wang, Ahmad F. Taha +3
Chlorine is a widely used disinfectant and proxy for water quality (WQ) monitoring in water distribution networks (WDN). Chlorine-based WQ regulation and control aims to maintain p…
Flood Risk Mitigation and Valve Control in Stormwater Systems: State-Space Modeling, Control Algorithms, and Case Studies
Marcus N. Gomes Junior, Marcio H. Giacomoni, Ahmad F. Taha +1
The increasing access to non-expensive sensors, computing power, and more accurate forecasting of storm events provides unique opportunities to shift flood management practices fro…
Revisiting the Water Quality Sensor Placement Problem: Optimizing Network Observability and State Estimation Metrics
Ahmad F. Taha, Shen Wang, Yi Guo +4
Real-time water quality (WQ) sensors in water distribution networks (WDN) have the potential to enable network-wide observability of water quality indicators, contamination event d…
State Estimation in Water Distribution Networks through a New Successive Linear Approximation
Shen Wang, Ahmad F. Taha, Lina Sela +2
State estimation (SE) of water distribution networks (WDNs) is difficult to solve due to nonlinearity/nonconvexity of water flow models, uncertainties from parameters and demands,…
Receding Horizon Control for Drinking Water Networks: The Case for Geometric Programming
Shen Wang, Ahmad F. Taha, Nikolaos Gatsis +1
Optimal, network-driven control of Water Distribution Networks (WDN) is very difficult: valve and pump models form non-trivial, combinatorial logic; hydraulic models are nonconvex;…
A Fixed-Point Iteration for Steady-State Analysis of Water Distribution Networks
Mohammadhafez Bazrafshan, Nikolaos Gatsis, Marcio Giacomoni +1
This paper develops a fixed-point iteration to solve the steady-state water flow equations in an urban water distribution network. The fixed-point iteration is derived upon the ass…
