Description
Descriptive definition of BD Carthage content: "an elementary hydrographic section corresponds to the axis of the bed of a river, stream or canal"
The polylines are drawn a priori in the direction of the flow of the section.
The minimum length of a stretch is 200 meters on the ground.
Cutting of sections is carried out according to:
- A change of attribute in the fields of the table,
- A change in the type of environment: the section crosses a surface area, for example,
- A change in the morphological facies of the watercourse (single arm, anastomosis),
- The presence of a jump (expressed as a break in the slope),
These modifications are identified by photo-interpretation of the available orthoimages.
