    • Drought Management of Existing Water Supply System 

      Dean Randall; Mark H. Houck; Jeff R. Wright (American Society of Civil Engineers, 1990)
      A multi‐objective linear program is developed to study the operation of a metropolitan water supply system during drought. The Indianapolis Water Company is used as a case study. Twelve pressure districts, three reservoirs, ...

    • Discharger Grouping for Water Quality Control 

      J. Wayland Eheart; E. Downey Brill, Jr.; Jon C. Liebman (American Society of Civil Engineers, 1990)
      In developing management programs to regulate point sources of waterbomewaste, it may be convenient or even necessary to subdivide the dischargers into groups. For simplicity and effectiveness in meeting water quality ...

    • Hydrometric Network Evaluation: Audit Approach 

      Zal K. Davar; William A. Brimley (American Society of Civil Engineers, 1990)
      An evaluation of the hydrometric network of New Brunswick was performed starting from basic principles of hydrometric network design and proceeding through the analysis of the present network and its ability to meet user ...

    • Production, Cost, and Increased Salinity in Water 

      Donald E. Agthe; J. Craig Tinney (American Society of Civil Engineers, 1989)
      Water customers suffer hidden private costs if complete price information is not provided when the salinity in water increases. Previous attempts to estimate the damages or hidden costs resulting from increased salinity ...

    • Bayesian Inferencing Applied to Real‐Time Reservoir Operations 

      Anibal Armijos; Jeff R. Wright; Mark H. Houck (American Society of Civil Engineers, 1990)
      A significant amount of research during the past few years has focused on the application of expert systems technology to problems of water resources management. While these investigations have led to speculation as to the ...

    • Decision Support for Estuarine Water Quality Management 

      Uwe Arnold; Gerald T. Orlob (American Society of Civil Engineers, 1989)
      Management of water quality in estuarine systems is a multistepped process, ranging from characterization of the hydrological and hydromechanical properties that govern water quality changes through identification of waste ...

    • Hydropower Optimization Via Sequential Quadratic Programming 

      Gustavo E. Díaz; Darrell G. Fontane (American Society of Civil Engineers, 1989)
      Optimal allocation of powerplant releases during peak demand periods carries an economic advantage in the operation of hydropower systems interconnected to large electrical networks. This paper presents an alternative ...

    • Comparison of Method of Residuals and Cluster Analysis for Flood Regionalization 

      Nageshwar R. Bhaskar; Carol A. O'Connor (American Society of Civil Engineers, 1989)
      The method of residuals was recently used by the U.S. Geological Survey (USGS) to delineate seven flood regions for the state of Kentucky. An alternative approach is to use cluster analysis in conjunction with important ...

    • Optimal Operation of Water Distribution Systems 

      U. Zessler; U. Shamir (American Society of Civil Engineers, 1989)
      Optimal operation of a water supply system is solved by progressive optimality (PO), an iterative dynamic programming (DP) method. Given the forecasted demands for the coming 24 hr, the initial and final conditions in the ...

    • Correlated Versus Uncorrelated Hydrologic Samples 

      Hugo A. Loaiciga; Paul F. Hudak (American Society of Civil Engineers, 1989)
      Spatial data are collected at various locations. Two cases are considered: (1) The observations are independent; and (2) the observations are correlated. If the data are assumed to be normally distributed with constant ...

    • Remote Sensing and Fully Distributed Modeling for Flood Forecasting 

      Tao Tao; Nicholas Kouwen (American Society of Civil Engineers, 1989)
      The advantage of introducing Landsat‐derived land‐cover information into a flood‐flow forecasting model is examined. Two modeling alternatives, with and without Landsat data, were applied to 10 km by 10 km grid sizes. The ...

    • Discussion of “<i>Water Distribution Reliability: Analytical Methods</i>” by Janet M. Wagner, Uri Shamir, and David H. Marks (May, 1988, Vol. 114, No. 3) 

      I. C. Coulter; P. Jacobs (American Society of Civil Engineers, 1989)

    • Water and Urban Land‐Use Planning in Cali, Colombia 

      Mark A. Ridgley (American Society of Civil Engineers, 1989)
      A multiobjective urban land‐use/water‐resource model, appropriate for use at the strategic planning level in less‐developed countries (LDCs), is described and applied to Cali, Colombia. Objectives are to minimize service ...

    • Discussion of “<i>Multicriterion Selection of Wastewater Management Alternatives</i>” by Aregai Tecle, Martin Fogel, and Lucien Duckstein (July, 1988, Vol. 114, No. 4)
