The balance between inputs(precipitation) and outputs(river discharge and evapotranspiration). |
|
|
What does the water balance affect? |
How much water is stored in the basin. |
|
|
What happens in wet seasons? |
Precipitation exceeds evaporation, the creates a water surplus. The ground stores fill with water so theres more surface run off and higher discharge, so river levels rise. |
|
|
What happens in drier seasons? |
Precipitation is lower than evapotranspiration. Ground stores are depleted as some water is used (by plants and humans) and some flows into the river channel but isnt replaced by precipitation. |
|
|
What happens at the end of the dry season? |
Deficit (shortage of water in the ground) stores are recharged in the next wet seasons. |
