Answer:
Water
Step-by-step explanation:
The land use change affects the surface water run off deeply. For instance - A forest receiving high rainfall, will generate low surface water runoff as the plants and trees will obstruct the free flowing water. Along with this the land will also absorb a large amount of water there by reducing its flow volume.
Now in case if forest land is turned into a residential area, then the land will be covered by roads and buildings and there will be no water absorption by land. Thus, the surface water runoff will increase.
