Fig. 15. Distribution of the upstream and downstream slope.

Considering the upstream slope, more than the 27% of the sections have a slope greater than 10% and for the downstream this number becomes 68%. This parameter indicates the sections of less stability. Another important element is the relative height defined by the following ratio: � � � � � � (1)
