Resumen
This thesis work compares the behavior of different likelihood functions of the GLUE
methodology in the classification of roughness coefficients of mountain rivers (three river
morphologies: Cascade, Plane Bed and Step-pool) obtained from models. Bibliographic
research on likelihood functions used to obtain roughness coefficients on rivers was carried
out, and then these functions were used to classify a set of modeled data using as comparison
parameters values measured in the field. The results showed an almost similar behavior
between likelihood functions with the exception of some cases that tend to validate roughness
coefficients that differ considerably with the values measured in the field. Finally, it can be
seen that a likelihood function, depending on the parameters that are incorporated, can be as
simple as the researcher wishes, making the complex function excessively particular to the
river being analyzed, limiting its applicability to other rivers with similar characteristics.
