Improved Techniques in Regression‐Based Streamflow Volume Forecasting
(American Society of Civil Engineers, 1992)Although multiple linear regression has been used for many years to predict seasonal streamflow volumes, typical practice has not realized the maximum accuracy obtainable from regression. Several techniques can help provide ... -
Multireservoir Sewer‐Network Control Via Multivariable Feedback
(American Society of Civil Engineers, 1992)This paper considers the problem of optimal water distribution to several retention reservoirs in an urban sewer network during rainfall. The goal of the control actions is the minimization of overflows and eventually the ... -
Planning and Management of Water‐Resource Systems in Developing Countries
(American Society of Civil Engineers, 1992)The multipurpose use of water in all types of human activities and the intensive development and urbanization of settlements have resulted in a considerable increase in water demand and water pollution. This is why it is ... -
Optimal Operation of Multiple‐Reservoir System
(American Society of Civil Engineers, 1993)A monthly planning and operational model has been developed for the Adelaide headworks system in South Australia, Australia. The model uses linear goal programming to aid in the identification of optimum operating policies ... -
Partitioning Phosphorus Loads: Implications for Lake Restoration
(American Society of Civil Engineers, 1992)An extensive tributary monitoring program was undertaken to evaluate phosphorus loads to Onondaga Lake—a hypereutrophic water body near Syracuse, New York. The resulting phosphorus budget indicates that diversion of treated ... -
Optimization of Real‐Time Hydrothermal System Operation
(American Society of Civil Engineers, 1992)A procedure for the economic optimization of hydrothermal power systems operation has been developed. The procedure is suitable for on‐line system utilization on a daily basis. To alleviate the inherent high dimensionality ... -
Adequacy of Surface Water‐Supply Systems: Case Study
(American Society of Civil Engineers, 1992)Water‐supply planners and managers must continually evaluate the ability of surface water sources to meet current and future demands of public water‐supply systems they serve. Water demand changes over time, increasing ... -
Model for Prescribing Ground‐Water Use Permits
(American Society of Civil Engineers, 1992)In 1986 the Massachusetts Water Management Act was passed, allowing greater control over both surface and ground‐water withdrawals. The act has the dual goal of allowing sustained economic growth and protecting the natural ... -
Closure to “<i>Recurrence Interval of Geophysical Events</i>” by Hugo A. Loaiciga and Miguel A. Marino (May/June, 1991, Vol. 117, No. 3)
(American Society of Civil Engineers, 1992) -
Simulating THM Formation Potential in the Sacramento Delta. Part II
(American Society of Civil Engineers, 1992)An existing numerical hydrodynamics and water‐quality model was employed to simulate trihalomethane (THM) precursors and salinity transport in California's Sacramento‐San Joaquin Delta. Using steady‐state assumptions and ... -
Storm‐Water Detention Storage Design under Random Pollutant Loading
(American Society of Civil Engineers, 1992)A set of equations for computing storm‐water detention storage‐capacity‐treatment‐rate combinations as a function of pollutant trap efficiency and relevant hydrologic statistics is provided. The hydrologic variables of ... -
Discussion of “<i>Recurrence Interval of Geophysical Events</i>” by Hugo A. Loaiciga and Miguel A. Marino (May/June, 1991, Vol. 117, No. 3)
(American Society of Civil Engineers, 1992) -
Closure to “<i>Optimal Upgrading of Hydraulic‐Network Reliability</i>” by Lindell Ormsbee and Avner Kessler (November/December, 1990, Vol. 116, No. 6)
(American Society of Civil Engineers, 1992) -
Hydrologic Parameter Estimation Using Geographic Information System
(American Society of Civil Engineers, 1992)The use of geographic information systems (GIS) can make the task of compiling necessary spatial data and the required hydrologic parameters for modeling watershed runoff relatively easy. Furthermore, recent advances in ... -
Simulating THM Formation Potential in Sacramento Delta. Part I
(American Society of Civil Engineers, 1992)TWO empirical relationships are developed that describe bromide impacts on the distribution of trihalomethane (THM) compounds measured by California's Department of Water Resources (DWR) THM formation potential test. These ... -

(American Society of Civil Engineers, 1992) -
Aggregation‐Disaggregation Approach to multireservoir operation
(American Society of Civil Engineers, 1992)A group of optimization models for the real‐time operation of a hydropower system of reservoirs is presented in this paper. The dimensionality problems usually found in dynamic programming formulations are solved by a ... -
Irrigation and Drainage—Systems Policy Analysis and India Case Study
(American Society of Civil Engineers, 1992)Irrigation was one of the earliest efforts, supplementing agriculture, in the ascent of man. With the recent population explosion, it has become a critical issue in man's survival, and in environmental conservation. ... -
Research/Application of System Engineering to Water Resources Systems
(American Society of Civil Engineers, 1992)Throughout 20 years, especially the recent decade, system engineering has been extensively researched on and applied to the water conservancy and hydroelectric power in China, involving the development and utilization of ... -
Optimal Pump Scheduling in Water‐Supply Networks
(American Society of Civil Engineers, 1992)The electricity cost of pumping accounts for a large part of the total operating cost for water‐supply networks. This study presents a method based on linear programming for determining an optimal (minimum cost) schedule ...
