Probabilistic Assessment of Extended Detention Basins: Role of Model Parameter Uncertainty
Publisher: ASCE
Abstract: This study investigates the role of parameter uncertainty on evaluation of stormwater control measures. Specifically, several formal and informal Bayesian uncertainty analysis techniques are linked with the modified Fair ...
Assessing Uncertainty in Multicriteria Evaluation of Centralized and Decentralized Dual Water Supply Strategies
Publisher: ASCE
Abstract: As much of our urban water supply infrastructure reaches the end of its useful life, water managers are using the opportunity to explore alternative strategies that enable them also to utilize alternative local water sources ...
Chronic and Acute Coastal Flood Risks to Assets and Communities in Southeast Florida
Publisher: ASCE
Abstract: Chronic and acute coastal flood risks in Miami-Dade County are assessed over the range of sea-level rise (SLR) scenarios for the coming decades. The HAZUS-MH coastal flood hazard modeling and loss estimation tool are used ...
Appraisal of Steady-State Stormwater Control Measure Pollutant Removal Models within a Dynamic Stormwater Routing Framework
Publisher: ASCE
Abstract: In this study, three different stormwater control measures (SCMs) pollutant removal models, consisting of the linear regression model, modified Fair and Geyer (MFG) model, and k-C* model, were simulated under both steady-state ...
Model Development for Biotrickling Filter Treatment of Graywater Simulant and Waste Gas. I
Publisher: American Society of Civil Engineers
Abstract: A mathematical model was developed to simulate a biotrickling filter capable of simultaneous treatment of graywater simulant and waste gas contaminated with ammonia and hydrogen sulfide. The model accounts for mass transfer ...
Model Sensitivity Analysis for Biotrickling Filter Treatment of Graywater Simulant and Waste Gas. II
Publisher: American Society of Civil Engineers
Abstract: A detailed sensitivity analysis was conducted to identify key parameters for a biotrickling filter simultaneously treating graywater and waste gas containing ammonia and hydrogen sulfide contaminants. Sampling-based ...
Uncertainty in Flood Inundation Mapping: Current Issues and Future Directions
Publisher: American Society of Civil Engineers
Abstract: This paper presents key issues associated with uncertainty in flood inundation mapping. Currently flood inundation extent is represented as a deterministic map without consideration to the inherent uncertainties associated ...
Application of Multicriteria Decision Analysis with A Priori Knowledge to Identify Optimal Nonpoint Source Pollution Control Plans
Publisher: American Society of Civil Engineers
Abstract: Control of agricultural nonpoint sources of pollution is achievable through implementation of conservation practices at the farm or field level. There are several approaches to achieve a targeted implementation of conservation ...
Progress and Promise Transitioning to the One Water/Resource Recovery Integrated Urban Water Management Systems
Publisher: American Society of Civil Engineers
Abstract: Changing circumstances and the availability of new technologies are causing urban water systems to transition from managing system components in a separate and linear fashion to an integrated “One Water” approach that ...
Method for Assessing Impacts of Parameter Uncertainty in Sediment Transport Modeling Applications
Publisher: American Society of Civil Engineers
Abstract: The predictions from a numerical sediment transport model inevitably include uncertainty because of assumptions in the model’s mathematical structure, the values of parameters, and various other sources. In this paper, the ...
