RISLoop-by-Loop Cutting Algorithm to Generate Layouts for Urban Drainage Systems
Publisher: American Society of Civil Engineers
Abstract: The design of urban drainage systems consists of solving two subproblems: (1) generating the layout and (2) sizing the sewers. The latter includes pipe diameters, installation depths, and pumping facilities, all of which ...
Straightforward Transient-Based Approach for the Creep Function Determination in Viscoelastic Pipes
Publisher: American Society of Civil Engineers
Abstract: This work introduces a simple and straightforward approach for the creep function determination in viscoelastic pipes on the basis of transient flow analysis. The governing equations are expanded and analytically solved ...
Machine Learning–Assisted Model for Leak Detection in Water Distribution Networks Using Hydraulic Transient Flows
Publisher: ASCE
Abstract: This study introduces a novel hybrid leak detection method based on machine learning (ML) and hydraulic transient modeling for pipe networks. First, the transient hydraulic simulation model is developed in the time domain. ...

Deterministic Integrated Optimization Model for Sewage Collection Networks Using Tabu Search
Publisher: American Society of Civil Engineers
Abstract: This paper presents an integrated optimization model for designing sewage collection networks. The layout configuration is designed using the loop-by-loop cutting algorithm. Then, the network with a given layout is ...
Computer-Aided Decision-Making Model for Multiphase Upgrading of Aged Water Distribution Mains
Publisher: American Society of Civil Engineers
Abstract: This study introduces a decision support system for upgrading aged water distribution mains. The network hydraulics is simulated and evaluated by a hybrid reliability measure, and the design period is divided into multiple ...
Simultaneous Optimization of Operating Rules and Rule Curves for Multireservoir Systems Using a Self-Adaptive Simulation-GA Model
Publisher: American Society of Civil Engineers
Abstract: This study introduces a simulation-optimization model for deriving an operating policy for multireservoir systems. Two adjustable monthly rule curves are introduced to each reservoir in the system. The applied rule curves ...
Toward Sustainable Urban Drainage Infrastructure Planning: A Combined Multiobjective Optimization and Multicriteria Decision-Making Platform
Publisher: ASCE
Abstract: This study aims to introduce a generic solution in the context of a multicriteria decision making (MCDM) platform to (1) facilitate the optimization of hybrid (de)centralized urban drainage infrastructures with many ...
Optimization of Conventional Rule Curves Coupled with Hedging Rules for Reservoir Operation
Publisher: American Society of Civil Engineers
Abstract: As a common approach to reservoir operating policies, water levels at the end of each time interval should be kept at or above the rule curve. In this study, the policy is captured using rationing of the target yield to ...
Hanging Gardens Algorithm to Generate Decentralized Layouts for the Optimization of Urban Drainage Systems
Publisher: American Society of Civil Engineers
Abstract: Traditional urban drainage systems rely heavily on centralized network-based infrastructures. Recently, the idea of centralized urban drainage networks has increasingly been questioned. The latest investigations suggest a ...
