Surface ponding occurs when water accumulates on flat surfaces and cannot be carried away by runoff. Flash flooding occurs suddenly and is usually caused by heavy rainfall or a sudden release of water from a dam or levee. Riverine flooding occurs when a river or stream overflows its banks. Alluvial fan flooding occurs when sediment and debris from a mountainous area accumulate in a flat area, causing flooding during heavy rainfall. The best choice for the given scenario is surface ponding.
