What outcome results when an increase in sediment deposition alters lake bathymetry?

💡 Explanation

A shallower lake bed encourages a steeper hydraulic gradient down a slight slope because of reduced channel depth and greater friction; this, in turn, encourages **meandering**, therefore leading to a braided stream rather than a single channel. Saltwater intrusion and canons require separate processes.

• Which mechanism sustains high sinuosity in meandering streams within humid continental regions?
• Which primary mechanism causes cyclical avulsions on the apex of an alluvial fan?
• Which phenomenon causes melting in the mantle wedge above a subducting oceanic plate?
• Which mechanism causes secondary volcanic cones to form on the flanks of stratovolcanoes?
• Which outcome increases when highly soluble bedrock groundwater withdrawal exceeds recharge?
• Which risk increases when a megathrust earthquake occurs along a subduction zone lacking strain partitioning?
