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.
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.
The factors responsible for the formation of various drainage patterns include the underlying geology, slope of the land, climate, and human activities. These factors determine how water flows across the landscape, leading to the development of dendritic, radial, rectangular, trellis, or parallel drainage patterns.
