1. A computer-implemented method for civil engineering, the method comprising:
obtaining a mesh representing a terrain and a polyline on the mesh; and
computing a contributor of the polyline, the contributor being a set of mesh points that represents points of the terrain from which water necessarily flows toward a terrain point represented by a point of the polyline, the computing of the contributor including:
modifying the mesh by determining, based on the polyline, a trench below the polyline,
computing a watershed segmentation of the terrain based on the modified mesh, and
based on the computed watershed segmentation, identifying, on the modified mesh, a basin including the trench, the contributor corresponding to the identified basin.
