This paper assesses the utility of statistical models by examining methodological issues associated with empirical analysis of hydraulic and channel geometry relationships. It also describes and presents examples of advanced statistical models
The rank adjacency statisticD provides a simple method to assess regional clustering. The usual normal approximation is found to give inaccurate results if the data are sparse and some regions have tied ranks. Ajusted formulae for the moments of D

Statistical models are proposed that capture the essential features of the structure of a population composed of geographically defined groups and can encompass grouping processes and contextual effects. They are used to show how small effects

Identification of strength equilibrium rock slopes : further statistical considerations
to delimit the envelope are reviewed and modifications are proposed that permit its more rigorous statistical definition. The structural relation between the variables is estimated by regressing RMS on O, and the strength equilibrium envelope is defined
