Which mechanism promotes delta formation when a sediment-laden river enters a lake environment?

💡 Explanation

When a sediment-laden river encounters a lake, the slowing water velocity reduces carrying capacity causing suspended clay particles to flocculate due to reduced agitation and electrolyte concentration gradients. Therefore flocculation results increasing sedimentation and building a delta, rather than convection, oxidation, or bioaccumulation which operate through different forcing mechanisms.
