Question

In which area would surface water most effectively infiltrate into the local groundwater system?

a. A stream in a steep-sided bedrock canyon in the mountains
b. Streams flowing in the numerous channels of an alluvial fan
c. A playa lake with a thick mud bottom
d. All of the above would promote infiltration

Answer 1

Option B is correct.

Step-by-step explanation:

Infiltration depends greatly on the features of the soil. If the soil has excessive clay or mud, water will not find a way into the groundwater system and will remain as surface water.

An alluvial fan is a perfect location for this since there will be little or no resistance to the flowing water. The streams are already a connection with the groundwater system, and falling water will flow directly to it.
