All the water that is stored in rivers, streams and other drainage channels.

• A. Surface storage
• B. Channel storage
• C. Groundwater recharge
• D. Irrigation

Answer: (B)

The water stored in rivers and streams resides in the actual channels, within the riverbed and banks, between flood events. This is known as channel storage—the portion of the drainage system’s water that is held directly in the channels themselves. It differs from surface storage, which includes ponds, lakes, and reservoirs on the land surface; groundwater recharge refers to water infiltrating down to replenish aquifers; and irrigation is the practice of applying water to crops. So, the water that sits in the river and stream channels is channel storage.
