Multiple studies demonstrate that large woody debris plays a critical role in shaping channel morphology, regulating sediment and flow retention, and providing essential habitat structure for aquatic organisms such as trout.
Papers 0, 1, and 2 directly support the claim that large woody debris alters river morphology and aquatic habitats. The remaining papers discuss other topics like general geomorphology, macroinvertebrates, impoundments, or alternative substrate effects without refuting the claim. Thus, the evidence strongly supports the statement.
