The siphuncle swelling at the apex is subtriangular in longitudinal profile.
2.
The venter is almost uniformly convex in longitudinal profile.
3.
They have convex-up longitudinal profiles.
4.
Curvature is exogastric, meaning the lower, or ventral, side is convex in longitudinal profile.
5.
The siphuncle is large and slightly removed from the ventral side, that with the concave longitudinal profile.
6.
Within the mountains the river is long, the gradient of its longitudinal profile is per kilometer, and the basin area is.
7.
Knickpoint, also called a nick point or simply nick, represents breaks in slopes in the longitudinal profile of a river caused by rejuvenation.
8.
Knick point, also called a nick point or simply nick, represents breaks in slopes in the longitudinal profile of a river caused by rejuvenation.
9.
In a Digital Elevation Model ( DEM ), the longitudinal profile of a wind gap shows a convex-upwards trend and that of a water gap shows a concave-upwards or linear trend.
10.
Below Lake Akkul'( its absolute elevation is 3, 140 m ), the longitudinal profile undergoes another sharp drop because a large mountainous obstruction damming the lake and, perhaps, because of moraines buried under the obstruction.
