Deep Reinforcement Learning for Real-Time Optimization of Pumps in Water Distribution Systems
(ASCE, 11/1/2020 )Real-time control of pumps can be an infeasible task in water distribution systems (WDSs) because the calculation to find the optimal pump speeds is resource intensive. The computational need cannot be lowered even with ... -
Evaluating Optimization Objectives in Linear Quadratic Control Applied to Open Canal Automation
(ASCE, 11/1/2020 )Proportional-integral (PI) control, as one of the most popular classic control methods, has been applied widely to the real-world practice of canal automatic control. The performance of a PI controller largely depends on ... -
The Nile Water-Food-Energy Nexus under Uncertainty: Impacts of the Grand Ethiopian Renaissance Dam
(ASCE, 11/1/2020 )Achieving a water, food, and energy (WFE) nexus balance through policy interventions is challenging in a transboundary river basin because of the dynamic nature and intersectoral complexity that may cross borders. The Nile ... -
Usage and Effect of Multiple Transient Tests for Pipeline Leak Detection
(ASCE, 11/1/2020 )The value of multiple transient tests under the same experimental conditions for the purpose of leakage detection is assessed. The gain in signal-to-noise ratio and leakage detection accuracy due to the multiple tests are ... -
Assessing the Hydrologic Response of Key Restoration Components to Everglades Ecosystem
(ASCE, 11/1/2020 )The Everglades is a large, complex, and highly managed ecosystem, and its natural hydrologic properties, water quality, soils, flora, and fauna have been significantly altered by the Central and Southern Florida Project. ... -
Generation of Water Demand Time Series through Spline Curves
(ASCE, 11/1/2020 )A novel application of spline curves was developed for tracing average daily trends of water demand. These trends were used as input of a stochastic model to generate synthetic time series considering the number of water ... -
Robust Strategy for Assessing the Costs of Urban Drainage System Designs under Climate Change Scenarios
(ASCE, 11/1/2020 )Uncertainty inherent in precipitation predictions from general circulation model (GCMs) may lead urban drainage systems to be underdesigned (or overdesigned) in the future. This issue can be mitigated with the use of risk ... -
Reservoir Operational Performance Subject to Climate and Management Changes in the Willamette River Basin, Oregon
(ASCE, 10/1/2020 )Reevaluation of the reliability of reservoirs in meeting operating objectives is needed as the landscape and operational priorities change. This study examined the individual and collective changes in reservoir performance ... -
Expected Benefits of Laos’ Hydropower Development Curbed by Hydroclimatic Variability and Limited Transmission Capacity: Opportunities to Reform
(ASCE, 10/1/2020 )Massive investments in hydropower are transforming several river basins across the world—especially in developing countries, where hydroelectricity is often seen as a means to sustain economic growth. While the environmental ... -
Balancing Ecological Requirements and Power Generation in Reservoir Operation in Fish Spawning Seasons
(ASCE, 9/1/2020 1)Various studies have demonstrated that the long-term flow regime plays an important role in stimulating fish spawning. The flow regime is altered by the construction and operation of reservoirs. In this study, a flow-regime ... -
Hourly and Daily Urban Water Demand Predictions Using a Long Short-Term Memory Based Model
(ASCE, 9/1/2020 1)This case study uses a long short-term memory (LSTM)–based model to predict short-term urban water demands for the Hefei City of China. The performance of the LSTM-based model is compared with the autoregressive integrated ... -
Ecological Optimal Operation of Hydropower Stations to Maximize Total Phosphorus Export
(ASCE, 9/1/2020 1)Cascade reservoirs have interrupted the distribution and transportation of nutrients, which brings environmental and ecological problems. However, the current ecological operation methods focusing on the hydrologic regime ... -
Multiobjective Scheduling Method for Short-Term Peak Shaving Operation of Cascade Hydro Plants
(ASCE, 9/1/2020 1)With structural changes in power consumption, peak load demands and peak-valley differences are growing, which motivates peak shaving operations of hydropower systems. A multiobjective mixed-integer nonlinear programming ... -
Regularization of an Inverse Problem for Parameter Estimation in Water Distribution Networks
(ASCE, 9/1/2020 1)An accurate hydraulic model of a water distribution network (WDN) is a critical prerequisite for a multitude of operational, optimization, and planning tasks. The accuracy of a hydraulic model can only be maintained through ... -
Identification of Influential User Locations for Smart Meter Installation to Reconstruct the Urban Demand Pattern
(ASCE, 8/1/2020 1)This paper aims to show how the total demand signal (i.e., the sum of all user demands) of a district metered area (DMA) can be reconstructed using simple linear models starting from the readings taken at influential ... -
Probabilistic Multi-Step-Ahead Short-Term Water Demand Forecasting with Lasso
