    • Planning Water Supply and Sanitation Projects in Developing Countries 

      Suley A. Muyibi (American Society of Civil Engineers, 1992)
      Despite the laudable objectives of the International Drinking Water Supply and Sanitation Decade (IDWSSD) launched in 1980, developing countries are still faced with inadequate water supply and poor sanitation in rural and ...
    • Multiobjective Analysis of Multireservoir System 

      S. Mohan; Diwakar M. Raipure (American Society of Civil Engineers, 1992)
      The explicit consideration of multiple objectives in decision making is becoming increasingly important in water resources systems analysis. Conflicting objectives like irrigation, flood control, hydropower production, and ...
    • Reservoir Management and Thermal Power Generation 

      Barbara J. Lence; M. Imran Latheef; Donald H. Burn (American Society of Civil Engineers, 1992)
      Heated effluent from thermoelectric power stations may adversely affect river ecology if adequate dilution water is not available. If the effluent is discharged to a regulated waterway, however, the adverse water‐quality ...
    • Operation of Large Multireservoir Systems Using Optimal‐Control Theory 

      Numan R. Mizyed; Jim C. Loftis; Darrell G. Fontane (American Society of Civil Engineers, 1992)
      The utility of optimal‐control theory for the deterministic operation of very large multireservoir systems is demonstrated for a real situation, the complex multireservoir Mahaweli system in Sri Lanka. This system includes ...
    • Rationalizing Water Requirements with Aid of Fuzzy Allocation Model 

      Janusz Kindler (American Society of Civil Engineers, 1992)
      This paper considers water resources planning, specifically the case in which there is limited capability to expand water supply capacities by means of structural solutions. Under such circumstances, all measures that ...
    • Managing Lower Colorado River 

      Daniel P. Sheer; Timothy J. Ulrich; Mark H. Houck (American Society of Civil Engineers, 1992)
      The lower Colorado River system, which is managed by the Bureau of Reclamation (BuRec), comprises three major dams (Hoover, Davis, and Parker). There is a significant hydroelectric capacity in the southwestern system, but ...
    • Systems Analysis Applications at Hydrologic Engineering Center 

      Arlen D. Feldman (American Society of Civil Engineers, 1992)
      In the broadest sense of systems analysis, the Hydrologic Engineering Center (HEC) has been actively applying systems analysis techniques since its inception in 1964. HEC's basic systems analysis method has been the ...
    • Reservoir Systems Analysis: Closing Gap between Theory and Practice 

      Slobodan P. Simonovic (American Society of Civil Engineers, 1992)
      During the past three decades, the application of the systems approach to reservoir management and operations has been established as one of the most important advances made in the field of water resources engineering. A ...
    • Water Resource Systems Models: Their Role in Planning 

      Daniel P. Loucks (American Society of Civil Engineers, 1992)
      Planning is an integral part of water resources development and management. Whether or not particular plans or programs are eventually implemented, the planning process itself forces us to think about what we are or should ...
    • Systems Analysis in Ground‐Water Planning and Management 

      William W.‐G. Yeh (American Society of Civil Engineers, 1992)
      The objective of this paper is to review the state of the art of systems analysis and optimization techniques developed in the field of water resources for the planning and management of a ground‐water system. The areas ...
    • Reviewers of the <i>Journal of Water Resources Planning and Management</i> 

      Unknown author (American Society of Civil Engineers, 1992)
    • Use of Mathematical Programming Methods for Complex Systems 

      James G. Uber; E. Downey Brill, Jr.; John T. Pfeffer (American Society of Civil Engineers, 1992)
      Although mathematical programming techniques can be applied to solve certain (type A) problems, they cannot be used to solve complex (type B) problems directly. Instead they can be used to generate alternative solutions ...
    • Water‐Quality Modeling for Decision Making 

      G. T. Orlob (American Society of Civil Engineers, 1992)
      Today, mathematical modeling has become an accepted part of the process of establishing and evaluating alternative scenarios for water‐quality management. The proliferation of microcomputers, the general availability of ...
    • Systems Analysis in Water‐Distribution Network Design: From Theory to Practice 

      I. C. Goulter (American Society of Civil Engineers, 1992)
      Review of the use of system‐analysis techniques, and in particular optimization, to design water‐distribution networks reveals that in spite of the considerable development of models in the literature they have not been ...
    • Jury Verdict: Frequency Versus Risk‐based Culvert Design 

      Gary L. Lewis (American Society of Civil Engineers, 1992)
      A federal district court jury in Cheyenne, Wyoming, ruled that an Act‐of‐God defense could not be used when a railroad culvert backed water onto residential properties during a catastrophic “10,000‐year” rainstorm. The ...
