2 cards from this section. Quick, good the night before a test.
What does the W-Index account for in hydrology?
Think about what happens when rain first starts.
How does using the W-Index improve water management?
Consider the effects of accurate predictions.
What is the W-Index used for in hydrology?
Remember the role of the W-Index during heavy rains.
True or False: The W-Index only applies to soil types with high porosity.
Consider how different soils absorb water.
Given a rainfall event with an initial loss of 10 mm and an average infiltration rate (W-Index) of 15 mm/hour, calculate how long it will take before runoff begins if the rainfall rate is 30 mm/hour.
Use the effective rainfall to find how long it takes to exceed the infiltration rate.
Examine a scenario in which the W-Index for a specific area is forecasted to decrease due to urban development. Discuss potential impacts on local water management practices.
Consider how urbanization impacts soil and impervious surfaces.
