Human Causes Of Flashy And Subdued Hydrograph Flashcards
1
Q
How does urbanisation affect a hydrograph
A
More impermeable surfaces, so runoff increased and surface storage and infiltration are reduced
2
Q
How does pastoral farming affect a hydrograph
A
Ground trampled so less interception and more surface runoff
3
Q
How does deforestation affect a flood hydrograph
A
Less interception by trees, so water reaches the ground and river more quickly
More surface runoff and greater flood risk
