Prevention
Prevention – management that is focused on stopping the flood from occurring in the first place.
.
Protection
Protection – management that is focused on protecting areas and people from the negative effects of flooding.
Soft engineering
Soft engineering – working with the river to limit the amount of damage from flooding. For example, afforestation.
Hard engineering
Hard engineering – Building structures to prevent the flood from happening. For example, dam building.
Strategy
Strategy – a plan of action or method.

Lag time
Lag time – the amount of time between peak rainfall and peak discharge
Rising limb
Rising limb – the increase in river discharge
what do the bars represents?
The bars represent the amount of precipitation
Peak discharge
Peak discharge – the highest level of water in the river
Falling limb
Falling limb – the decrease in river discharge
Peak rainfall
Peak rainfall – the highest amount of rainfall.
