Comparison of Methods for Predicting Deficient-Network Performance
(American Society of Civil Engineers, 1996)When a nodal demand is excessive as in a fire-flow condition or when a pump fails or a pipe breaks, a water distribution system (WDS) may temporarily become deficient and unable to satisfy all nodal demands. However, the ... -
Regional Flood Frequency with Hierarchical Region of Influence
(American Society of Civil Engineers, 1996)Regional flood frequency analysis involves combining extreme-flow information from numerous stations to enhance the reliablity of the temporal characterization of extreme-flow data at sites with short periods of record. ... -
Modeling Reservoir Evaporation Losses by Generalized Networks
(American Society of Civil Engineers, 1996)Using a generalized network formulation, the nonlinear evaporation loss function of a reservoir is directly incorporated in a water-supply-optimization model. The nonlinear function is first piecewise-linearized and the ... -
Discussion and Closure: Alluvial Fan: Proposed New Process-Oriented Definitions for Arid Southwest
(American Society of Civil Engineers, 1996) -
Reliability of Remediation Designs in Presence of Modeling Error
(American Society of Civil Engineers, 1996)An optimal hydraulic gradient control (OHGC) design involves the joint use of optimization and simulation models. When an imperfect ground-water simulation model is used, the reliability of the OHGC design has to be ... -
Modeling Low Velocity/High Dispersion Flow in Water Distribution Systems
(American Society of Civil Engineers, 1996)Under most circumstances, dispersive processes can be neglected in water distribution systems due to high velocities and low dispersion coefficients that ensure that advective transport dominates constituent spreading. ... -
Optimal Management of a Coastal Aquifer in Southern Turkey
(American Society of Civil Engineers, 1996)Seven ground-water management models were developed to determine the optimal planning and operating policies of a costal aquifer in sourthern Turkey threatened by saltwater intrusion. Steady-state and transient finite-element ... -
Fuzzy Rule-Based Modeling of Reservoir Operation
(American Society of Civil Engineers, 1996)A fuzzy rule-based model is constructed to derive operation rules for a multipurpose reservoir. The case study of the Tenkiller Lake in Oklahoma illustrates the methodology. Operation rules are generated on the basis of ... -
Discussion and Closure: Streamflow Forecasting for Han River Basin, Korea
(American Society of Civil Engineers, 1996) -
Chance-Constrained Optimal Monitoring Network Design for Pollutants in Ground Water
(American Society of Civil Engineers, 1996)A mathematical model for designing a ground-water-quality monitoring network is developed that links a ground-water pollution-transport simulation model and an optimization model. Tritium is considered as the (radioactive) ... -
Combining Geophysical and Well Data for Identifying Best Well Locations
(American Society of Civil Engineers, 1996)Geoelectric and well data are combined and used to delineate “best” well location areas. The best location is selected based on a compromise solution for two conflicting objectives: (1) maximum well yield (i.e., maximum ... -
Flood Forecasting Based on Radar Rainfall Measurements
(American Society of Civil Engineers, 1996)A hydrometerological study in a river basin was conducted to demonstrate the use of a weather radar for rainfall and flood-flow forecasting. The study region is a Pinioç river subbasin with a drainage area of 2,763 km -
Modeling Water-Resource Systems for Water-Quality Management
(American Society of Civil Engineers, 1996)Water managers have been attempting to operate reservoirs in a “best water management strategy” to meet specific project objectives since the first man-made impoundment was constructed. When it was realized, several years ... -
Reservoir Operating Rules with Fuzzy Programming
(American Society of Civil Engineers, 1996)Relatively little of the research on reservoir operating procedures has found its way into actual practice. One reason is that operators are uncomfortable with complex optimization models and reluctant to use procedures ... -
Integration of Water Resources Planning and Environmental Regulation
(American Society of Civil Engineers, 1996)Water resources analysts recognize that water resources planning should be comprehensive and multiply objective in nature, in contrast to planning centered on a single objective, such as flood control or irrigation. Despite ... -
WLS Method for Parameter Estimation in Water Distribution Networks
(American Society of Civil Engineers, 1996)The weighted-least-squares method based on the Gauss-Newton minimization technique is used for parameter estimation in water distribution networks. The parameters considered are: element resistances (single and/or group ... -
Controlling Microbial Biota Transfer in the Garrison Diversion Unit
(American Society of Civil Engineers, 1996)The Garrison diversion unit is a canal system designed to distribute water from the Missouri River basin into western and eastern North Dakota. Canada has opposed the completion of the Garrison diversion unit because of a ... -
Disaggregation Modeling Process for Climatic Time Series
(American Society of Civil Engineers, 1996)To assess the potential effects of climatic changes on water resources, it is important to incorporate predictions of future climatic trends into hydrologic planning models. Disaggregation models can be used to produce a ... -
Storm-Water Management Implementation through Modeling and GIS
(American Society of Civil Engineers, 1996)This paper presents an integration of a lumped parameter hydrologic model (Penn State Runoff Model) with a planning level geographic information system (GIS) in implementing a watershed-wide storm-water management plan. ... -
Pump-and-Treat Ground-Water Remediation System Optimization
(American Society of Civil Engineers, 1996)A ground-water management model using a nonlinear programming algorithm was developed to find the minimum cost design of the combined pumping and treatment components of a pump-and-treat remediation system and includes the ...
