Which outcome occurs when tectonic uplift reduces discharge on an alluvial fan system?

💡 Explanation

Reduced discharge lowers the system's capacity, leading to increased deposition of sediment by the mechanism of flow competence decline in proximal areas because the transport ability decreases; therefore, deposition is enhanced there, rather than further downstream.
