Questions: 15 | Attempts: 25 | Last updated: Mar 19, 2026

Sample Question 1
What does a stream hydrograph show?

The chemical composition of river water over time

The relationship between rainfall and streamflow discharge over time

The depth of soil layers along a river bank

The temperature of a river throughout the year

Sample Question 2
What is peak discharge on a hydrograph?

The lowest point of streamflow during a drought

The maximum volume of water flowing through a stream at a given point after a storm event

The average daily discharge of a river

The point where rainfall begins to fall in a watershed

Sample Question 3
The lag time on a hydrograph is the period between the peak of rainfall and the peak of stream discharge.

True

False

Urban Runoff Quiz: How Cities Change the Water Cycle

Questions: 15 | Attempts: 10 | Last updated: Mar 19, 2026

Sample Question
How does urbanization affect the velocity of surface runoff in a watershed?

It decreases runoff velocity by increasing soil absorption

It has no measurable effect on water movement

It increases runoff velocity by replacing permeable natural surfaces with impervious cover and channeling drainage networks

It slows runoff by increasing evapotranspiration from urban trees
