Short summary
We used a numerical model to study how mountain streams adjust to series of sediment input events, e.g., landslides. We recreated flume experiments with similar scope and then expanded their parameter space, allowing us to find conditions under which the stream becomes overloaded with sediment. This occurs when the stream cannot evacuate a sediment input in the time between pulses. Our results can help to better understand the long-term adjustment of mountain streams to episodic sediment supply.
