    • Water Conservation and Capacity Expansion 

      Jacobo Rubinstein; Leonard Ortolano (American Society of Civil Engineers, 1984)
      AS water becomes relatively more scarce and as the cost of developing new sources of water increases, projects designed to reduce the quantities of water consumed (i.e, demand management projects) become more attractive ...
    • Waste Application to Land: The Land‐Use Issue 

      William E. Cox (American Society of Civil Engineers, 1984)
      Projects for disposal of wastes by application to land must be implemented within a complex framework of institutional constraints, with landuse controls a significant component. Controls imposed by local government are ...
    • Long‐Range Reservoir Outflow Temperature Planning 

      Walter O. Wunderlich; Ming C. Shiao (American Society of Civil Engineers, 1984)
      A method for long‐range reservoir operation planning to meet an outflow temperature goal is described. The outflow temperature of TVA's Norris Reservoir is characteristic of the seasonally modified temperature regime ...
    • Real‐Time Reservoir Operations by Goal Programming 

      Emre K. Can; Mark H. Houck (American Society of Civil Engineers, 1984)
      Preemptive goal programming is applied to the real‐time, daily operation of multiple‐purpose, multiple‐reservoir systems. A significant advantage of the goal programming approach is that it may be based on physical operating ...
    • Flood‐plain Delineation in Ice Jam Prone Regions 

      Richard M. Vogel; Jery R. Stedinger (American Society of Civil Engineers, 1984)
      Flood‐plain delineation in ice jam prone regions is in its infancy. A methodology is introduced for incorporating the risk of ice jams into flood‐plain delineations in northern regions of the U.S. The distribution of flood ...
    • Increased Diversion at Chicago: Initial Assessment 

      Paul D. Kilburn; D. Jean Tate; Sally White (American Society of Civil Engineers, 1984)
      The Corps of Engineers has proposed and analyzed the effects of diverting Lake Michigan waters down the Illinois River in times of above average lake levels. Effects would vary considerably depending upon the rate and ...
    • Limitations on Seasonal Snowmelt Forecast Accuracy 

      Dennis P. Lettenmaier (American Society of Civil Engineers, 1984)
      Forecasting of seasonal snowmelt runoff is an important exception to the otherwise limited accuracy of long‐term runoff forecasts. Conceptual models of the snow accumulation and ablation and precipitation‐runoff processes ...
    • Water Management Using Interactive Simulation 

      Alfred B. Cunningham; John R. Amend (American Society of Civil Engineers, 1984)
      Interactive simulators utilizing current microprocessor technology have been developed and applied to several categories of contemporary water planning and management problems. Specific issues addressed include realtime ...
    • Ice‐Related Flood Damage Estimation 

      Charles E. Yoe (American Society of Civil Engineers, 1984)
      Ice jams are a major cause of flooding. Little has been done to develop methods for economic analysis of ice‐related flooding. Since the economic feasibility of a project is generally based on damages prevented, reliable ...
    • Managing a Public Involvement Program 

      Richard F. Astrack; Nancy A. Baumann; Gerald L. Reynolds (American Society of Civil Engineers, 1984)
      Developing a public involvement program and determining what procedures and methods are effective in water resources planning are described. Analysis is based on experiences in the development and management of a U.S. Army ...
    • Water Use and Public Policy in Florida 

      Andrew A. Dzurik (American Society of Civil Engineers, 1984)
      The interrelations of water use, population growth, and urbanization in the state of Florida are examined. Although the greatest freshwater use is for irrigation, the paper focuses on municipal use because of its projected ...
    • Irrigation in Humid Areas: Net Benefits 

      Richard S. Huebner; David F. Kibler; William R. DeTar (American Society of Civil Engineers, 1984)
      The use of irrigation systems in the humid east has traditionally been minimal due to frequent rainfall. The argument most often encountered against the use of irrigation in humid regions is that the return on investment ...
    • Brass Model: Practical Aspects 

      George F. McMahon; Robert Fitegerald; Brent McCarthy (American Society of Civil Engineers, 1984)
      The BRASS (Basin Runoff and Streamflow Simulation) model was developed to provide flood management decision support for operation of Savannah River system projects. BRASS is an interactive hydrologic/hydraulic model which ...
    • Time Patterns of Water Use in Six Texas Cities 

      David R. Maidment; Emanuel Parzen (American Society of Civil Engineers, 1984)
      Time series of monthly water use data from 6 Texas cities are examined. The time variation of the data may be divided into long memory (on average, 70% of total variation), short memory (15%) and residual error (15%). ...
    • The Role of Water Audits in Water Conservation 

      Gary A. Gagnon (American Society of Civil Engineers, 1984)
      Significant levels of water conservation can be achieved through control of leakage from a water distribution system. One of the best means of determining the level of water conservation which can be achieved is by conducting ...
    • Constraints to Managing Interstate Aquifer 

      David C. Noonan; Myron S. Rosenberg; Duncan W. Wood (American Society of Civil Engineers, 1984)
      Many considerations exist when attempting to manage a groundwater system that flows across interstate boundaries. The legal, institutional, and technical constraints managing one such system, the Coastal Plain Aquifer ...
    • Reservoir Operation: Choice of Objective Functions 

      Behzad Mohammadi; Miguel A. Marino (American Society of Civil Engineers, 1984)
      An efficient algorithm for the real‐time monthly operation of a multipurpose reservoir is presented. The model is a combination of linear programming (used for month‐by‐month optimization) and dynamic programming (used for ...
    • Agricultural Water Resources Management in India 

      Udai P. Singh (American Society of Civil Engineers, 1984)
