The nile is trellis
I would say Trellis because it doesn't look dendritic, but I can't be sure.

Dendritic
The Amazon River is an example of dendritic drainage, which resembles the branching pattern of tree roots. Dendritic drainage patterns are common in areas with uniform rock structure and slope, where rivers and streams flow in multiple directions.
The Amur River features dendritic drainage. This pattern of river system resembles the branching of tree roots and is common in areas with homogenous rock structures, where water flows in a branching pattern towards lower elevations.
trellis as the tributaries meet at approximately right angles
The Mississippi river is a dedentric drainage
describe the dendritic and trellis drainage pattern?
The amazon river is probably a trellis because it has 2 types of alternating soft and hard rocks. A trellis drainage is the rectangular drainage pattern created if rivers flow through alternating bands of hard and soft rocks.
The St. Lawrence River drainage system exhibits dendritic drainage, characterized by a network of streams that resemble tree branches. This pattern is typical of regions with uniform rock types and gradual slopes, allowing water to flow in a tree-like pattern towards the river.
Although we fully understand the words dendritic and trellis, they are not often applied to waterfalls and river systems, however such systems being a law unto themselves as far as flow patterns are concerned, the answer is 'yes' to both
