Description
This technical paper describes techniques available for assessing reservoir water quality conditions. There is a hierarchy of available techniques that reflects not only increasing requirements of time, cost, and technical expertise, but also accompanying increases in the degree of understanding and resolution of the problem and its causes. This hierarchy includes screening, diagnostic, and predictive techniques, which are described in Sections I through III, respectively. Screening procedures can be used initially to determine the existence of a problem, identify applicable assessment techniques, and suggest probable assessment approaches.
