iDrawlix® Mobile Premium
iDrawlix® Mobile Free
for Android
As one can see, within each cross section of iDrawlix® Mobile for Android, Users can choose two different roughness coefficients. One for the bottom and one for the sides. That can be useful in order to characterise two real different material composing any cross section, or conversely, to model the correct behavior of the cross section bottom in two different stages of his life cycle.
Indeed, is well known that with the time, the roughness coefficient characterising a certain material, can vary severely, assuming values sensibly far from his initial ones.
Furthermore, especially for sewers, it happens that the presence of sediments, due to the lack of self cleanising velocity, impose the necessity to have a correct model, in order to forecast the most real possible behavior of a certain sewer branch.
