Closure to “Reaeration Equations Derived from U.S. Geological Survey Database” by Charles S. Melching
Publisher: American Society of Civil Engineers
Discussion of “Need for Specification Format that Accommodates Engineered Projects” by Charles S. Barger
Publisher: American Society of Civil Engineers
Comparison of Kinematic-Wave and Nonlinear Reservoir Routing of Urban Watershed Runoff
Publisher: American Society of Civil Engineers
Abstract: The linkage of surface runoff in urban areas to water quantity and quality has been studied extensively in the literature. Many computer models based on different routing theories have been developed to simulate the ...
Comparison of Computed and Experimentally Assessed Times of Concentration for a V-Shaped Laboratory Watershed
Publisher: American Society of Civil Engineers
Abstract: In comparison with a kinematic wave–based equation for estimation of the time of concentration, three methods, Ben-Zvi’s method, the modified Ben-Zvi method, and Izzard’s method, were applied to determine the time of ...
Improved First‐Order Uncertainty Method for Water‐Quality Modeling
Publisher: American Society of Civil Engineers
Abstract: Uncertainties are unavoidable in water‐quality modeling and subsequent management decisions. Monte Carlo simulation and first‐order uncertainty analysis (involving linearization at central values of the uncertain variables) ...
Sensitivity Analysis of a Water-Quality Model Using Latin Hypercube Sampling
Publisher: American Society of Civil Engineers
Abstract: Decisions about water pollution control and management in river systems are increasingly based on predictions made with water quality models. Many uncertainties are associated with the development and calibration of such ...
Uncertainty in Coupled Nonpoint Source and Stream Water-Quality Models
Publisher: American Society of Civil Engineers
Abstract: Latin hypercube sampling (LHS) and the mean first-order reliability method are applied to determine the parameters significantly affecting uncertainty in the simulated dissolved oxygen (DO) concentrations at the point in ...
Evaluation of the Duration of Storm Effects on In-Stream Water Quality
Publisher: American Society of Civil Engineers
Abstract: One of the primary reasons water-quality standards are not met is the effect of storm runoff and combined sewer overflows. A methodology is presented here to determine the duration of storm effects on stream water quality. ...
