DMA Segmentation and Multiobjective Optimization for Trading Off Water Age, Excess Pressure, and Pump Operational Cost in Water Distribution Systems
Publisher: ASCE
Abstract: This study presents a heuristic multiobjective approach for segmenting and operating water distribution systems (WDS). The methodology employs a two-pronged strategy: the first is a heuristic method for dividing the network ...
IRFAM: Integrated Rule-Based Fuzzy Adaptive Resonance Theory Mapping System for Watershed Modeling
Publisher: American Society of Civil Engineers
Abstract: Watersheds are featured by a variety of hydrological, meteorological, and ecological characteristics. Complexity and uncertainty are usually two major challenges during watershed classification which is one of the key ...
Development of an Integrated Adaptive Resonance Theory Mapping Classification System for Supporting Watershed Hydrological Modeling
Publisher: American Society of Civil Engineers
Abstract: As it is a critical process of watershed management, classification always faces challenges of inefficiency in handling complexity and uncertainty. This study attempts to fill this gap by developing an integrated adaptive ...
Energy Dissipation of Debris Flows over Stepped Gradients and Erodible Beds in Open Channel
Publisher: ASCE
Abstract: Energy of debris flows in steep mountainous channels is mostly consumed by erosion, collision, and hydraulic jumps due to abrupt topographic changes. In this study, flume experiments were performed to study the energy ...
Monte Carlo Simulation–Aided Analytic Hierarchy Process Approach: Case Study of Assessing Preferred Non-Point-Source Pollution Control Best Management Practices
Publisher: American Society of Civil Engineers
Abstract: This paper presents an innovative Monte Carlo simulation—aided analytical hierarchy process (MC-AHP) approach by integrating the beta-PERT distribution, pairwise comparison, and Monte Carlo simulation. A case study related ...
Simulation-Based Inexact Two-Stage Chance-Constraint Quadratic Programming for Sustainable Water Quality Management under Dual Uncertainties
Publisher: American Society of Civil Engineers
Abstract: Water quality planning is complicated itself but further challenged by the existence of uncertainties and nonlinearities in terms of model formulation and solution. In this study, a simulation-based inexact two-stage ...
Effects of Bending Moments and Pretightening Forces on the Flexural Stiffness of Contact Interfaces in Rod-Fastened Rotors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rod-fastened rotor (RFR) is comprised of a series of discs clamped together by a central tie rod or several tie rods on the pitch circle diameter. The equivalent flexural stiffness of ...
