    • Coordination between Water Resources Development and Environmental Needs 

      William Whipple Jr. (American Society of Civil Engineers, 2001)
    • Long-Term Hydrologic Impact of Urbanization: A Tale of Two Models 

      Budhendra Bhaduri; Marie Minner; Susan Tatalovich; Jon Harbor (American Society of Civil Engineers, 2001)
      At a watershed scale, land-use change can increase runoff, flooding, and nonpoint source pollution and degrade downstream water bodies. Thus it is important to assess the potential hydrologic impacts of land-use change ...
    • Environmental Valuation and Its Economic Critics 

      Leonard Shabman; Kurt Stephenson (American Society of Civil Engineers, 2000)
      In the last few decades economists have devoted significant professional attention to developing and applying methods to place monetary values on environmental services. This paper summarizes the criticisms from within the ...
    • Reviewers of the <b><i>Journal of Water Resources Planning and Management</i></b> 

      Unknown author (American Society of Civil Engineers, 2000)
    • Recurrence Analysis of Hydrologic Droughts of Differing Severity 

      Jenq-Tzong Shiau; Hsieh Wen Shen (American Society of Civil Engineers, 2001)
      Droughts are stochastic in nature, therefore, statistical assessment of droughts is an attractive approach for water resources planning and management. In this study, a methodology of frequency and risk analysis of hydrologic ...
    • Economic Analysis of Water Service Investments and Tariffs in Cairo, Egypt 

      John P. Hoehn; Douglas J. Krieger (American Society of Civil Engineers, 2000)
      Donor agencies invested millions of dollars in the 1980s and 1990s to improve water and wastewater services in Cairo, Egypt. An economic analysis of these investments raised several issues relevant to planning and financing ...
    • Practical Estimation of Inflows into Multireservoir System 

      Cheng-shuang Peng; Nathan Buras (American Society of Civil Engineers, 2000)
      Reservoir system operation requires a variety of hydrologic information, of which streamflow data are most essential. Typically, available gauged streamflows are processed to represent flows at the location of a reservoir. ...
    • Economic Valuation of Resource Injuries in Natural Resource Liability Suits 

      Carol Adaire Jones (American Society of Civil Engineers, 2000)
      Several major federal environmental statutes enacted in the 1970s designate federal, state, and tribal resource management agencies as trustees of natural resources on behalf of the public and enable the trustees to recover ...
    • Jeddah City with and without Sewerage: Cost Comparison 

      O. S. Abu-Rizaiza (American Society of Civil Engineers, 2000)
      Fifty years ago, Jeddah, on the Red Sea Coast of Saudi Arabia, was a very small city. In recent decades it has grown rapidly but the sewerage system has not. As a result, there is extensive on-site wastewater disposal, ...
    • Determination of Low-Flow Characteristics for Texas Streams 

      Hanadi S. Rifai; Suzanne M. Brock; Katherine B. Ensor; Philip B. Bedient (American Society of Civil Engineers, 2000)
      Predictive equations for the harmonic mean flow; the 7-day, 2-year low-flow (7Q2); and the 7-day, 10-year low-flow (7Q10) of ungauged Texas streams are developed using multiple regression analysis based on meteorological ...
    • Estimating Ground-Water Damages from Hazardous-Substance Releases 

      Richard W. Dunford (American Society of Civil Engineers, 2000)
      At present there are 1,194 Superfund sites throughout the United States that are on the National Priorities List, because past releases of hazardous substances have contaminated natural resources and pose a human health ...
    • Valuing Beach Recreation Lost in Environmental Accidents 

      Robert T. Deacon; Charles D. Kolstad (American Society of Civil Engineers, 2000)
      This paper reviews methods that can be used to estimate the loss in use value associated with saltwater beach recreation in the case of an environmental accident, such as an oil spill. Particular attention is focused on ...
    • Value of Valuation: Introduction 

      John B. Braden (American Society of Civil Engineers, 2000)
      The principal focus of this special issue of the
    • Seasonal Risk Analysis for Floodplains in the Delaware River Basin 

      Kirk Weiler; M. Todd Walter; Michael F. Walter; Erin S. Brooks; Chris A. Scott (American Society of Civil Engineers, 2000)
      Overland pollutant transport via surface runoff and flooding is a primary concern in the management of agricultural land resources in the Delaware River Basin. The Catskills is home to multiple water reservoirs that supply ...
    • Cost-Benefit Analysis Based on Referendum CV: Dealing with Uncertainty 

      William J. Vaughan; Clifford S. Russell; Diego J. Rodriguez; Arthur H. Darling (American Society of Civil Engineers, 2000)
      An interesting and potentially important, but little appreciated, result of the use of dichotomous-choice contingent valuation (CV) techniques is that there are about a dozen ways to deal econometrically with the data on ...
    • Environmental Valuation Techniques in Water Resource Decision Making 

      John B. Loomis (American Society of Civil Engineers, 2000)
      Economic valuation of environmental uses of water resources has the potential to bring a more balanced perspective to the allocation and management of water resources. Environmental valuation allows water resource benefits ...
    • Optimal Operation of Water Distribution Pumps Considering Water Quality 

      A. Burcu Altan Sakarya; Larry W. Mays (American Society of Civil Engineers, 2000)
