Generation

# Sediment Transport Sediment transport is the movement of solid particles (sediment) by flowing water, wind, ice, or gravity. In rivers and streams, sediment moves through three main mechanisms: **bed load** (rolling/sliding along the bottom), **suspended load** (carried within the water column), and **wash load** (fine particles). The key formula is the **Shields parameter** (θ), which predicts the initiation of sediment motion: **θ = τ/(ρₛ - ρ)gD** where τ is bed shear stress, ρₛ and ρ are sediment and fluid densities, g is gravity, and D is particle diameter. Motion begins when θ exceeds a critical value (typically ~0.05).
