The influence of uncertainty on a hydrological model and a sensitivity analysis to account for imperviousness in drainage analysis

Abstract

The imperviousness of an urban catchment is maybe the most relevant parameter responsible of the peak. This study will be done based on a project where an assessment of a series of culverts is evaluated based on their hydraulic performance. One of the factors investigated is the influence of the imperiousness extent in the catchment (hydrological model) and what final impact may it have on the culverts behavior. Additionally, the effect of CC over he hydraulic behaviour will be tested too.
