Scenario-Based Robust Optimization of Regional Water/Wastewater Infrastructure

Doosun Kang and Kevin Lansey
Uncertainties facing water planners and designers include changes in demand due to community growth (temporal and spatial), per-capita water use, public perceptions, and regulations. One of the most powerful and intuitive ways to represent these uncertainties in the planning stage is to use scenario ...

A Proposed Smart Market Design for Sediment Discharge

Antonio A. Pinto, John F. Raffensperger, Thomas A. Cochrane, and E. Grant Read
Sediment discharge from erosion, urban run-off, and construction can cause environmental degradation. Governments try to regulate sediment, but the regulatory approach is costly to land owners. In principle, a market-based system could reduce costs, but the associated transaction costs are far too h ...

Iterative Methodology of Pressure-Dependent Demand Based on EPANET for Pressure-Deficient Water Distribution Analysis

Jun Liu and Guoping Yu
Traditional water distribution simulations which are referred to as demand-driven analysis (DDA) are normally analyzed under the assumption that nodal demands are known and satisfied. The DDA is valid under normal conditions and in design requirement. However, in many situations such as pipe burst o ...
