Which term describes water that provides alluvium and keeps the ground moist?

Explanation:
Flood water is the water from river floods that carries and drops sediment on the land, creating fertile alluvium and saturating the soil to keep it moist for crops. This combination—nutrient-rich sediment plus available moisture—makes floodplain areas highly productive for farming. The other options describe different ideas: human inputs are resources added by people, expenditure is money spent, and physical inputs are general natural resources, none of which specifically capture the role of flood waters delivering alluvium and moistening the ground.
