Seasonal / Temporal Changes - Water Cycle, Runoff and Hydrograph

Question 1

Spring

Answer 1

. More vegetation growth so more interception by vegetation

. Deciduous trees grow back leaves

. More infiltration

. Less overland flow

Question 2

Summer

Answer 2

. Less rain in summer

. Ground harder so more impermeable so less infiltration and less surface run off

Question 3

Autumn

Answer 3

. Less vegetation growth so less interception and infiltration

. More rainfall in autumn

Question 4

Winter

Answer 4

. Frozen ground may be impermeable and encourages overland flow

. If precipitation is in the form of snow, run off will be discouraged as the snow has to melt
