Abstract: Alternative methods to describe water quality using an aggregate index consisting of subindices for individual water quality variables are examined. Most aggregation methods suffer from three shortcomings: Ambiguity, ...

Abstract: The present practice for the design of primary settling tanks is based on the overflow rate corresponding to the percentage removal using isoremoval plots. The design procedure would be more rational if it were based on ...

Abstract: Alternative efforts to describe water quality by an aggregate index consisting of subindices of the constituent quality variables are examined. Ambiguity problems exist where all the subindices are acceptable and yet the ...

Abstract: In engineering design and analysis, mathematical models that generally involve a number of uncertain parameters are frequently employed for decision making. Over the years, a number of techniques have been developed to ...
