Channel Scouring Potential Logistic Analysis
Abstract
Water resource engineers often have to relate qualitative dependent
variables to one or more independent variables, which may or may not be
quantitative. In such circumstances, the use of conventional regression analysis
would encounter a number of difficulties. This paper introduces a statistical
method called logistic regression which is specially developed for such conditions.
The method is applied to a hydraulic problem of relating scouring potential in
a channel to depth and velocity of flow. Whether or not the methodology could
become a useful addition in water resources engineering analyses further
investigations and applications are necessary.
