How does climate influence the shape of a hydrograph?

There are 3 parts:

- Precipitation

- Temperature

- Antecedent moisture

Type of precipitation

Precipitation that falls as snow remains on grounds until it melts - can temporarily reduce discharge (hydrograph curve becomes less high - peak flow is lower & lag time increases)

Rapid melting means a rapid increase in discharge which can result in a short lag time & high peak flow as seen with a steep rising limb

Precipitation intensity

Heavy precipitation = increase in discharge & high peak discharge because there will be more water in drainage basin

Amount of moisture already in soil (antecedent moisture) will…
