2 cards from this section. Quick, good the night before a test.
What does basin shape affect?
Think about how water flows in a straight line.
Define drainage density.
Consider how many channels are in a given area.
What is the effect of a compact basin shape on runoff?
Think about how distance relates to travel time.
True or False: Higher drainage density always leads to more flooding.
Consider the efficiency of water channels.
Given a basin of irregular shape and a compact basin, discuss how each shape affects the runoff during a storm event, including the potential flood risks.
Think about water path lengths.
Calculate the drainage density of a basin with a total stream length of 120 km within an area of 300 km².
Remember to use total length over area.
