The dendritic pattern develops where the river channel follows the slope of the terrain. The stream with its tributaries resembles the braches of a tree , thus the name dendritic. It also flows underneath a rock that is the same hardness.

Dendritic drainage patterns
Dendritic drainage patterns are tree like while trellis drainage patterns are formed when tributaries meet at right angles so they look like squares or rectangles.
Most Indo-Gangetic Rivers have dendritic (tree-like) drainage pattern.
Dendritic drainage patterns resemble the branches of a tree, forming a network of tributaries that typically develop in areas with homogeneous rock types and gentle topography. In contrast, radial drainage patterns emerge from a central high point, such as a volcanic cone or mountain, with streams radiating outward like spokes on a wheel. The key difference lies in their formation: dendritic patterns are influenced by uniform geology, while radial patterns are shaped by topographic features.
The four major drainage patterns are dendritic, radial, rectangular and trellis. The factors that influence them are soil type, climate and the human interventions.
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.

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