What is evapotranspiration?
The main input in drainage basin cycle
The direct evaporation of moisture from the soil, bodies of water, and transpiration from plant leaves
The ability of vegetation to prevent precipitation reaching the ground
Overland flow transfers water in two ways. Look at the options below. Which option is NOT overland flow?
Rills
Sheetwash
Throughflow
What is runoff?
The total precipitation which flows over the surface of the basin
Channel precipitation
Baseflow
The final release of the water in a drainage basin is an output. Look at the options below. Which option is NOT an output?
Evapotranspiration
Condensation
Evaporation
The hydrological cycle within a drainage basin is described as an open system. What does this mean?
This means that there is a definite amount of water in the system and that this amount does not change
This means that there is a fixed amount of water in the system but this amount can change over time
This means that there is a varying amount of water in the system as inputs change depending on geographic location
