    • Drought Contingency Planning: Evaluating the Effectiveness of Plans 

      Anne Shepherd (American Society of Civil Engineers, 1998)
      This article reports results from a two-year research project to evaluate the effectiveness of drought contingency plans. The research developed a metalevel framework for evaluating plans before a drought. In addition, it ...

    • Probabilistic Model for Water Distribution Reliability 

      Chengchao Xu; Ian C. Goulter (American Society of Civil Engineers, 1998)
      A two-stage methodology for assessment of reliability of water distribution networks recognizing uncertainties in nodal demands, pipe capacity, reservoir/tank levels, and availability of system components is proposed. In ...
