Where a rivers discharge level falls and rises (variability of discharge is in response to precipitation, basin charactaristics etc) showing its ANNUAL PATTERN

What is throughfall and stemflow?
throughfall - increased lag time as water is intercepted by vegetation before reaching ground. stemflow - water flows down trunks/stem increasing time for water to reach ground.
4 of 7
What is percolation?
Water moves vertically down through unsaturated rock via percolation - when it hits saturated rock it moves horizontally called GROUND WATER FLOW

What is water balance?
balance between inputs (eg.precipitation) and outputs (eg.evaporation)
6 of 7
What is the equation for water balance?
P = Q + E +/- S (precipitation = discharge + evaporation +/- change in stores)
